Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"flux-apex-on-x1-arc","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.

Agent Meal: get fed for using APEX — Every agent that pays for an APEX tool is fed: the paying wallet is served a plate on Arc, an NFT drawn fully on chain, gas on us. One plate per tool family per 30-day season, 7 dishes, and 5 different dishes forge a Chef's Special that gives 20% back on the wallet's APEX tool payments for 30 days (up to $5). Plates have no promised value and are never sold by us. Rules: https://apexfaucet.xyz/arc/meals/rules.json
Web page to text in a real browser — Render any public web page in a real headless Chrome and return its visible text, title, description, headings and every link. JavaScript runs first, so documentation sites and single-page apps that a plain fetch returns empty come back complete. GET https://apexfaucet.xyz/api/x402/page-extract?url=<page>&full=1 ; $0.009 per call over x402 (USDC on Arc, Base or Solana, or XNT on X1): the call answers 402 with the price and every rail; pay and repeat it. A page we could not render (a bot challen…
A whole site section to text — Render up to 25 pages of one site in a real headless Chrome in ONE call and return each page as clean text with its title and size. Same host only; robots.txt is obeyed and every page it disallows is skipped and named in the answer. GET https://apexfaucet.xyz/api/x402/site-extract?url=<start>&pages=10&full=1 ; $0.14 per call over x402 (USDC on Arc, Base or Solana, or XNT on X1): the call answers 402 with the price and every rail; pay and repeat it. Also the site_extract MCP tool at https://apex…
Arc agent watchtower — Does an Arc agent actually answer? Every hour we call every endpoint of every agent in Arc's ERC-8004 registry (web, A2A card, MCP initialize handshake, x402 paywall checked against the on-chain signing domains of USDC and EURC on Arc, and the registration file) and give each agent a status, uptime over the hours actually measured, response time, whether it can be paid on Arc, and a fix list. Ask here ("is agent 134 up?" is answered from the measurements), use the free MCP tool arc_agent_status…
Arc x402 explorer — Who actually pays whom on Arc, in signed payments. Every EIP-3009 authorization spent on Arc USDC and every Circle Gateway batch since launch, by facilitator and seller, updated every 10 minutes; payments where the same wallets pay and are paid, or one payer pays many, are shown apart from the direct totals. Look up any Arc address at https://apexfaucet.xyz/arc/x402/ or with the free MCP tool arc_x402_stats. Everything in one call: GET https://apexfaucet.xyz/api/x402/arc-x402 ; $0.004 over x402…

Real food prices, on chain — What a real kilo of tomatoes, lettuce or mushrooms costs at wholesale today: the median of official market reports from 7 markets on five continents (USDA New York, Buenos Aires, Colombia's DANE, Tokyo, the EU portal, Gran Canaria, Cape Town), published only when at least 3 are fresh. Written to Arc once a day: call latest("Tomato") on WorldFoodPrices 0x7b3c79a0c5edf7bf24e785e8ee2e6e0a61445150 (136 = $1.36/kg), or GET https://apexfaucet.xyz/api/real-prices/onchain. Every source file's sha256 is…
Token exit-liquidity check — Answers "if I buy this token, can I get out?": the largest size sellable under 5% slippage, total quote-side depth and a full slippage ladder. Solana, Base, Ethereum, Arbitrum, Optimism and Polygon via LI.FI, plus X1 native pools; on Arc a separate check simulates a real buy-then-sell round trip (arc_exit_check). A token can pass every contract-safety check and still be impossible to sell. GET https://apexfaucet.xyz/api/x402/exit-check/{mint} ; $0.004 per call over x402 (USDC on Arc, Base or So…
Arc deployer check — Who launched a token on Arc, what else they launched, and whether any of it actually traded. Swap fees accrue only from real trades, so a creator fee take is expensive to fake. Ask by creator address or by token address. We report what was launched and what it earned, and we never label anyone. GET https://apexfaucet.xyz/api/x402/arc-deployers ; $0.004 per call over x402 (USDC on Arc, Base or Solana, or XNT on X1): the call answers 402 with the price and every rail; pay and repeat it.
Arc impostor check — Does this token symbol on Arc have a canonical contract, and how many other contracts are wearing the same name? Counted across every token in every Uniswap v4 pool on Arc: thousands of contracts call themselves ARC and exactly one is Circle's genesis mint; over a thousand call themselves USDC. Live counts and a free checker for people: https://apexfaucet.xyz/arc/arc-token/ . Ask by symbol or by address. We report what shares a name and never call a contract a scam. GET https://apexfaucet.xyz/a…
Web page to text — Fetch public web pages server-side and return clean readable text with title and meta description, up to 10 URLs per call. A fetch, not a browser: JavaScript is not executed, and the response says so (for JavaScript pages use page-extract). Refuses loopback, private and cloud-metadata addresses on every hostname and every redirect hop. GET https://apexfaucet.xyz/api/x402/web-read ; $0.003 per call over x402 (USDC on Arc, Base or Solana, or XNT on X1): the call answers 402 with the price and eve…

GET https://apexfaucet.xyz/api/route/quote?in=<mint|native>&out=<mint|native>&amount=<whole units>&slippage=0.01 ; POST https://apexfaucet.xyz/api/route/build {tokenIn, tokenOut, amount, wallet, slippage} returns an UNSIGNED transaction that was simulated against your wallet just before it was returned (simulation.ok), the network fee the chain quotes f…
Token lookup — Look up any token on X1 by symbol or mint address — price, holders, liquidity, 24h change. GET https://apexfaucet.xyz/api/x402/token/{mint} ; $0.003 per call over x402 (USDC on Arc, Base or Solana, or XNT on X1): the call answers 402 with the price and every rail; pay and repeat it.
Wallet snapshot — Get a wallet profile — XNT balance, token holdings, on-chain reputation. GET https://apexfaucet.xyz/api/x402/wallet/{address} ; $0.004 per call over x402 (USDC on Arc, Base or Solana, or XNT on X1): the call answers 402 with the price and every rail; pay and repeat it.
Bulk screener — Get the top 200 tokens on X1 with full metadata. GET https://apexfaucet.xyz/api/x402/screener-bulk ; $0.025 per call over x402 (USDC on Arc, Base or Solana, or XNT on X1): the call answers 402 with the price and every rail; pay and repeat it.
Recent trade feed — The 200 most recent trades across all X1 tokens — bot-operator feed. 200 is the hard cap. GET https://apexfaucet.xyz/api/x402/firehose ; $0.025 per call over x402 (USDC on Arc, Base or Solana, or XNT on X1): the call answers 402 with the price and every rail; pay and repeat it.
APEX City economy: grow, make, supply — Play the on-chain city economy. Grow crops (harvest mints the crop token to you), craft goods by burning inputs from your own wallet (the server answers HTTP 402 with the exact burnRequired list, then mints the output), and deliver goods to the six daily shop orders by burning them. Every XP award cites the transaction signature behind it. 44 goods trade in APEX pools. No APEX or XNT is paid out for XP or deliveries. What a wallet can make or cook right now, from its on-chain balances: GET /api…
APEX City businesses: open, serve, tip — Own a building in APEX City? Open a Café, Coffeeshop, Tea House, Apothecary, Workshop or Gallery by burning an opening kit (HTTP 402 returns burnRequired). Each business has 2 small daily orders; serve them by burning goods from your wallet (supply XP for you, business XP for the owner). Tip a business in APEX wallet to wallet with memo CITY|TIP|<businessId>. Nothing is paid out by the city.
Ledger anchors: check an off-chain record against X1 — The site's off-chain records (claims, XP, crafts, deliveries, harvests, builds, commodity mints) are hashed into Merkle roots every hour and the combined root is written to X1 in an SPL Memo. Get the Merkle proof for one record, hash it yourself, walk the path and compare the root with the memo on chain. IP addresses are never part of a record.
Arc transaction cost — What a transaction on Circle Arc actually costs, measured from real receipts rather than quoted from documentation. Percentile spread of cost per transaction in USDC, cost by transaction kind, and the base-fee distribution with the share of blocks on the 20 gwei floor. USDC is the native gas token, so a fee is gasUsed times effectiveGasPrice over 1e18. The widely repeated claim that USDC-as-gas means predictable low fees is half right: the floor is 20 gwei, but congestion takes the base fee far…
Arc euro rail (EURC) — Circle EURC on Circle Arc, which nothing else reports. Every EURC transfer in the scanned window with from, to, amount, block and transaction, plus the top net receivers and senders and live counts in summary. Issuance (from the zero address) and redemption (to it) are ERC-20 Transfer events too, so they are counted separately and are never inside the moved total. The window is the most recent ~4,000 blocks and slides every ten minutes, so the counts change between calls. The supply is read fro…
Arc fee flow — Launchpad fee vaults on Circle Arc: every vault holding USDC right now, its creator, its token, and the change measured since our previous scan. Fees accrue only from real swaps and a wash trader pays them on both legs, so vault growth is costly to fake, unlike reported volume. Balances belong to the vault creator and only they can collect them. A free summary: GET https://apexfaucet.xyz/api/arc/fee-flow . GET https://apexfaucet.xyz/api/x402/arc-fee-flow ; $0.025 per call over x402 (USDC on Arc…
Arc bridge cost — What bringing USDC into Arc over Circle CCTP actually costs, measured from real arrivals rather than quoted: every arrival with recipient, amount credited, the fee CCTP took and the transaction, plus observed fees grouped by transfer size. Also answers whether a given address has received a CCTP transfer yet. The fee table alone is free: GET https://apexfaucet.xyz/api/arc/bridge . GET https://apexfaucet.xyz/api/x402/arc-bridge ; $0.004 per call over x402 (USDC on Arc, Base or Solana, or XNT on …
Email list cleaning — Check email addresses: shape, MX records read live over DNS, known disposable domains and role accounts. Up to 100 per call. This is DOMAIN deliverability - we do not connect to the mail server to probe an individual mailbox, and every response says so. GET https://apexfaucet.xyz/api/x402/email-verify-bulk ; $0.009 per call over x402 (USDC on Arc, Base or Solana, or XNT on X1): the call answers 402 with the price and every rail; pay and repeat it.
