Added "strategy_backtest" (48 tools before, 49 now)
Strategy backtest (crypto, daily closes) ($0.009) — PAID ($0.009 USDC via x402). Backtest a simple, stated trading rule on a crypto asset's daily USD closes from Coinbase Exchange and compare it with buying and holding over the same window. Strategies: sma_cross (long while the fast simple moving average is above the slow one), rsi_reversion (buy below rsiBuy, sell above rsiSell), dca (buy a fixed slice every dcaEveryDays), buy_and_hold. Signals formed at one close are executed at the next (no look-ahead); a fee of feeBps per trade; long or flat only. Returns total return, buy-and-hold return, max drawdown, Sharpe, exposure, win rate, the trad…
Added "token_verdict" (47 tools before, 48 now)
Token verdict (EVM + Solana) ($0.009) — PAID ($0.009 USDC via x402). Should your agent touch this token? One call returns a 0-100 safety score, a grade (A-F), a verdict (low_risk, medium_risk, high_risk, critical_risk), the reasons that took points off and what speaks for it, the scanner's own flags (identical to token_safety), and the deepest DEX pair's price, liquidity, volume and age. Works for an ERC-20 on base, ethereum, polygon, arbitrum, optimism, bsc or avalanche, and for a Solana mint (send the base58 address; chain is inferred). The scoring rules are published in every answer (method). Send no body to get USDC on Base. Ru…

ENS & Basename resolver (both ways, with profile records) ($0.0027) — PAID ($0.0027 USDC via x402). ENS both ways: a name (vitalik.eth, or a Basename like jesse.base.eth) to its address, or an address to its primary name — which the Universal Resolver verifies resolves back — plus the profile records the name's owner published: url, X/Twitter, GitHub, description and the raw avatar record (not fetched). Read from Ethereum mainnet over public RPCs; Basenames resolve through ENS's off-chain lookup, whose gateway URLs are fetched through FiatDock's SSRF guard. ASCII names only (letters, digits, hyphens). A name with no address, or an address with no primary name, …
Academic paper search (OpenAlex, ~250M works) ($0.018) — PAID ($0.018 USDC via x402). Search the scholarly literature: OpenAlex (~250M works across every discipline, including arXiv and PubMed; CC0 metadata), with Crossref answering when OpenAlex does not. Each paper comes with title, the first six authors and the author count, year and date, venue, type, DOI and link, citation count, a free full-text link when one is known, and the abstract (up to 1,200 characters). Filter by year range and open access; sort by relevance, most cited or newest — the citation and date sorts match title and abstract so the results stay on topic. No match answers 404 …
Latest satellite images of any point (Sentinel-2) ($0.0225) — PAID ($0.0225 USDC via x402). The newest satellite images of any coordinate, from the Copernicus Sentinel-2 Level-2A archive (free, open imagery; ~10 m per pixel; a revisit every ~5 days) via Element 84's Earth Search catalogue: for each scene the capture time, cloud cover, MGRS tile, sun elevation, a small JPEG preview link and the full-resolution true-colour image as a Cloud-Optimized GeoTIFF. Filter by a cloud limit (default 30%) and a look-back window (default 60 days, up to 365); newest first. No scene in the window answers 404 and is not charged.

Call any x402 endpoint — Call a pay-per-call x402 endpoint from the public index (find it with search_x402) — any host, not only FiatDock listings. TO BUY: call once WITHOUT `payment` to get the endpoint's 402 decoded (its price, its payTo, the EIP-712 domain) plus step-by-step instructions, sign ONE entry of accepts — the one on a network you can pay — with your own wallet, then call again with the same url/method/body plus `payment` set to the base64 x402 payload; the money goes straight from your wallet to the endpoint's payTo, FiatDock takes no fee and never touches it. No wallet? `npx fiatdock-mcp` with AGENT_PR…
Check an email address ($0.001) — PAID ($0.001 USDC via x402). Is this address worth sending to? Syntax, the domain's DNS (MX, then A/AAAA), disposable-provider and role-mailbox lists, a free-provider flag, a typo suggestion (gmial.com -> gmail.com), a normalized form (Gmail dots and +tags collapsed), and a risk verdict — low / medium / high / undeliverable — with reasons. No SMTP probe: it vouches for the DOMAIN, never the mailbox. An invalid address is a paid verdict (that IS the answer); a DNS failure answers 502 and is not charged. Without payment this returns the 402 challenge; the fiatdock-mcp npm package pays automatic…
Search the public x402 index — Find any pay-per-call x402 endpoint on the internet — the public x402 index (~15,000 priced endpoints from hundreds of hosts), not only FiatDock's own marketplace. Ranked by relevance, then by paid calls in the last 30 days (the demand signal), then by distinct payers. Each row carries the URL, the price the index recorded, the network, where the money goes, and the 30-day call/payer counts; call_x402 then reads the endpoint's own 402 and pays it directly from your wallet — FiatDock takes no fee and never touches the money. Read-only, free. Use search_services for FiatDock marketplace listing…

Company financials from SEC XBRL ($0.0045) — PAID ($0.0045 USDC via x402). A US-listed company's financials as it filed them with the SEC (XBRL company facts), by ticker (AAPL, BRK-B) or CIK: for its last 1-12 fiscal years (10-K) or three-month quarters — revenue, net income, diluted EPS, total assets, total liabilities, stockholders' equity, cash, operating cash flow, shares outstanding — each with the us-gaap tag it came from, the fiscal year/period and the filing. Restatements win; a value the company did not tag is null, never computed (no derived Q4). US-GAAP filers only (not IFRS). An unknown ticker or an SEC outage answers 404/50…
RSS / Atom feed reader ($0.0022) — PAID ($0.0022 USDC via x402). Read any public RSS 2.0, RSS 1.0 (RDF) or Atom feed and get its title, link and description plus up to 100 items in feed order: title, link, published and updated (null when unreadable), a plain-text summary (HTML removed, at most 500 chars), author and id. Fetched through the SSRF guard (private addresses refused, at most 3 redirects, each re-checked). An HTML page answers 422 naming the feed it links to; an empty feed is 404; an unreachable feed 502 — none charged. An empty body reads https://hnrss.org/frontpage. JSON Feed is not read. The text is the publisher…
Hacker News search and front page ($0.0027) — PAID ($0.0027 USDC via x402). Search Hacker News or read its front page, via the HN Search API by Algolia: stories, comments, Ask HN or Show HN, by relevance (text match, then points) or newest first, optionally only the last N hours. Each item has title, link, discussion URL, author, points, comment count, time and, for comments and text posts, the text as plain text (at most 2,000 chars). Words match as written (no typo matching). front_page is ordered by points, not HN's own rank. Points are as of the read. No match is 404 and an unreachable search 502, neither charged. The text is HN user…
npm / PyPI package safety and maintenance ($0.0027) — PAID ($0.0027 USDC via x402). Before adding a dependency: give an npm or PyPI package (and optionally an exact version; default latest). Returns every vulnerability OSV.dev lists for that version (ids, CVE aliases, severity as its database labels it, fixed versions), whether it is deprecated (npm) or yanked (PyPI), licence, https source repository, publish dates, latest version, last week's downloads, runtime dependency and maintainer counts, and risk flags from a stated rule list. It reads registry metadata and advisories, not the code; 'no vulnerabilities' means none known to OSV. An unknow…
Public holidays by country (and is this date one?) ($0.001) — PAID ($0.001 USDC via x402). Every holiday Nager.Date lists for a country and year (nationwide and regional, with its types), and for one date (default today, UTC): isHoliday (a nationwide Public holiday only), the other nationwide and regional holidays that day, and the next nationwide public holiday that year. Coverage depends on the source: ~200 countries, not e.g. Saudi Arabia, the UAE or India (404); regional and observance coverage varies. A country or year it does not cover is 404, an outage 502 - not charged. Without payment this returns the 402 challenge; the fiatdock-mcp npm package…
Time zone conversion (IANA tz database, DST-aware) ($0.001) — PAID ($0.001 USDC via x402). Shows one instant in up to 20 IANA time zones (localTime with offset, utcOffset, abbreviation, isDst, dayOfWeek, date). `time` with Z/offset is absolute; without, it is wall-clock in `from` (default UTC). A skipped local time moves forward by the gap, a repeated one takes the earlier instant (localTimeIssue + alternativeInstantUtc). Rules come from the tz database built into the server; future dates use today's published rules. An unknown zone answers 404, bad input 400; neither is charged. Without payment this returns the 402 challenge; the fiatdock-mcp npm packa…
Weather forecast for any point (MET Norway, 9 days) ($0.0018) — PAID ($0.0018 USDC via x402). Forecast for any coordinate from MET Norway's Locationforecast 2.0 (global): the current hour (temperature, humidity, wind, cloud, next-hour rain, symbol), rows up to `hours` ahead (1 h steps ~2.5 days, then 6 h, each stating its period), and up to 9 UTC-day rows with min/max (incl. MET's 6-hour extremes), total precipitation and the main condition. Times UTC; MET's CC BY 4.0 attribution included. No air quality or alerts. Upstream failure is not charged.

New & boosted token screener (DexScreener) ($0.009) — PAID ($0.009 USDC via x402). Which tokens just appeared or are being pushed right now: the union of DexScreener's public lists (newly created token profiles, community takeovers, and tokens whose teams paid for a boost), each with the numbers to judge it from its most liquid pair — price, liquidity, 1h and 24h volume, 24h buys and sells, 1h/24h price change, market cap, FDV, pair age and links.

x402 market leaderboard (who earns, from how many payers) ($0.009) — PAID ($0.009 USDC via x402). Who is actually earning on x402: every seller (host) in Coinbase's public x402 discovery index, read hourly, with its 30-day paid calls, paying wallets, calls per payer (near 1.0 = a one-off sweep, higher = repeat buyers), estimated revenue (calls × listed price, counted only for resources priced in USDC on a known chain), median price, networks and its most-called resource. Rank by revenue, calls or payers; filter by keyword (e.g. "search", "token safety") and network; minPayers (default 3) drops sellers whose only payers are their own testers. Useful to price a …

The latest crypto headlines from nine newsrooms — CoinDesk, Cointelegraph, Decrypt, The Block, Blockworks, Bitcoin Magazine, The Defiant, Crypto Briefing, DL News — merged, de-duplicated and newest first, each with its link, publisher, time and a short summary. Filter by keywords (every word must appear) and a window of 1-168 hours. A feed that is down is reported in sources; a window with no matching headline answers 404 and is not charged.

Best DeFi yields by chain and token (DefiLlama) ($0.001) — PAID ($0.001 USDC via x402). Where a token earns the most, from DefiLlama's yield index: pools filtered by chain (default Base; "all" for every chain), token symbol (USDC, ETH, cbBTC…), stablecoin-only and a minimum TVL (default $1M), sorted by APY or TVL — each with total, base (fees/interest) and reward APY, the 30-day mean, 7-day change, IL risk, exposure and a DefiLlama link. Statistical outliers are excluded unless includeOutliers is true. Data, not financial advice. Without payment this returns the 402 challenge; the fiatdock-mcp npm package pays automatically.

Domain intel: registration, DNS, email auth, TLS ($0.0045) — PAID ($0.0045 USDC via x402). Everything about a domain in one call: the registrar, creation and expiry dates, age, status and nameservers from the registry's own RDAP service; live DNS (A, AAAA, MX, NS); email authentication (the SPF record and the DMARC policy); and the TLS certificate port 443 serves — issuer, validity window, days remaining, whether it covers the name and whether a browser would trust it. Accepts a bare domain or a URL. A TLD whose registry runs no RDAP returns registration null with the reason. A non-existent domain is a paid answer (exists:false); a resolver and registr…
FX rates + conversion (live, with the ECB rate beside it) ($0.001) — PAID ($0.001 USDC via x402). Live exchange rates and a conversion: how many units of each target currency one unit of `from` buys (a live mid rate), the converted amount, and — where the European Central Bank publishes one — its daily reference rate and the deviation between the two, an independent check in the same answer. ~170 fiat currencies plus BTC, ETH and other majors. Defaults to USD against EUR, GBP, JPY, CNY, CHF, CAD, AUD, INR. An unknown currency answers 404 and is not charged. Rates for information, not an executable quote. Without payment this returns the 402 challenge; the fiat…
Perp market + funding (Hyperliquid, Binance, Bybit) ($0.001) — PAID ($0.001 USDC via x402). Hyperliquid perpetual futures in one call: mark, oracle and mid price, 24h change, the funding rate per interval and its simple annualised APR, open interest (coins and USD), 24h volume and max leverage — plus, for a named coin, its NEXT funding on Binance and Bybit (as Hyperliquid publishes it) for cross-venue funding comparison. Omit coin for the most-traded markets by 24h volume. An unknown coin answers 404 with the nearest names. Without payment this returns the 402 challenge; the fiatdock-mcp npm package pays automatically. Any answer the tool cannot produce …
Prediction markets (Polymarket) ($0.0045) — PAID ($0.0045 USDC via x402). Live prediction markets from Polymarket: for each open market, every outcome with its price (the price of one share, 0-1 USDC, read as the market's implied probability), 24h and total volume, liquidity, closing date and a link. Search by topic, or omit the query for the markets with the most 24h volume. A query that matches no open market answers 404 and is not charged. Market prices, not forecasts — not financial advice.

Prompt-injection check for untrusted text ($0.0045) — PAID ($0.0045 USDC via x402). Scan text you are about to read — a fetched web page, an email, a tool description, another agent's message — for the shapes that hijack agents: instruction-override phrasing, a redefined system role or persona, requests to move credentials or keys, hidden directive tags and invisible Unicode. Returns a verdict (malicious / suspicious / no_known_pattern) and every pattern found with its severity. The same ruleset scans every FiatDock marketplace listing. Pattern-based: no_known_pattern is not a guarantee. Up to 8,000 characters per call; nothing is stored. Withou…
SEC filings by ticker (EDGAR) ($0.0027) — PAID ($0.0027 USDC via x402). A US-listed company's latest SEC filings from EDGAR, by ticker (AAPL, BRK-B) or CIK: newest first, each with form type, filing and report date, accession number, description, an 8-K's item codes (2.02 results, 5.02 officer changes…) and a direct link to the document on sec.gov — plus the company's name, CIK, tickers, exchanges and industry. Filter by form types (10-K, 10-Q, 8-K, 4, DEF 14A…). An unknown ticker answers 404 and is not charged. Public-domain data, not investment advice. Without payment this returns the 402 challenge; the fiatdock-mcp npm package pay…
Website contacts: socials, role emails, phones ($0.0027) — PAID ($0.0027 USDC via x402). How to reach the organisation behind a website, read from its own HTML (the homepage, plus its contact page when linked): social profiles (X, LinkedIn company pages, GitHub, YouTube, Instagram, Facebook, TikTok, Telegram, Discord, Reddit, Farcaster, Bluesky…), role email addresses (info@, sales@, support@, press@…), phone numbers from tel: links, and contact-page URLs. Addresses that look like a person's are never returned — only counted. Up to 3 redirects followed, each safety-checked; JavaScript is not run (a JavaScript-only page answers 422, not charged). With…
Token holders & concentration ($0.0027) — PAID ($0.0027 USDC via x402). Who holds an ERC-20: the top 10 holders with their share of supply and whether each is a contract (a pool, bridge or vault), locked, or a burn address; the LP holders and how much LP is locked; the creator's and owner's own share; the holder count; and concentration both raw (top10Pct) and with burned/locked supply left out (top10ControlledPct). Base by default, also ethereum, polygon, arbitrum, optimism, bsc, avalanche. Send no body to get USDC on Base.

Wallet portfolio on Base (every token, priced) ($0.0045) — PAID ($0.0045 USDC via x402). What a Base address owns, in one call: the ETH balance read from the chain, every ERC-20 it holds with balance, market price and USD value, and a USD total. Tokens with no market price are listed but not counted; tokens the explorer flags (airdropped spam imitating a real token) are listed, flagged and NOT counted. Send no body to get the wallet that pays. Very large wallets can time out (502, not charged). Without payment this returns the 402 challenge; the fiatdock-mcp npm package pays automatically.
