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":"gate402","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.

Declared by sources
What the publisher says
Attributed to the source that supplied each field. Treated as claims, not facts.
Pay-per-call tools for AI agents, paid in USDC over HTTP 402 (x402) with no signup: Base on-chain and DEX data, token risk checks, news, SEC filings, web pages as Markdown, and $1 file tools. LLM calls on open models are relayed to openrouter.ai (a hosted model API) and priced per token. Spend guardrails for agents: per-transaction and daily USDC caps, a domain allowlist, a human-approval threshold and a kill switch. GPU owners can list an OpenAI-compatible endpoint and be paid per call. No GPUs are online yet. Also an MCP server: npx -y gate402-mcp.
nodeproxy — Fetch any public URL, render client-side JS, strip nav/ads, return clean LLM-ready Markdown.
nodeproxy-stealth — Anti-bot fetch for Cloudflare / JS-heavy protected pages: routed through rotating residential proxies with automatic JS rendering and CAPTCHA solving, returned as clean LLM-ready Markdown. Best-effort on the hardest targets.
tokensqueezer — Compress text before an LLM reads it: strip filler, collapse JSON, densify prose. The response reports estimated input and output tokens (from character and word counts, not a model tokenizer) and the percent saved on your own text.
onchain_intel — On-chain wallet & token intelligence on Base: native + ERC-20 balances, EOA/contract detection, tx count, and token metadata. From public RPC.
dex_market — Live DEX price, liquidity, and 24h volume for a Base token across its trading pairs.
token_risk — Rug/tradeability risk verdict for a Base token: a 0-100 score and SAFE/CAUTION/AVOID call from liquidity depth, 24h volume, DEX diversity, pool age, ERC-20 validity, holder concentration, and a live honeypot/sell-tax simulation. Judgment for trading agents, not raw data.
launch_radar — Radar of the freshest Base token launches (newest DEX pools), lightly pre-screened by liquidity/age/flow with quickFlags for obvious junk. Top-of-funnel discovery for trading agents; feeds token-risk / momentum / best-swap. From GeckoTerminal.
best_swap — Best-execution intel for a Base token: which DEX pool to trade on and the estimated price impact + total cost for a given trade size, ranked across pools with a split suggestion. Constant-product estimate for trading agents: the execution plan, not a firm quote.
momentum_signal — Factual momentum + order-flow signal for a Base token: price trend (5m-24h), buy/sell pressure, volume trend, classified RISING/FALLING/FLAT + ACCUMULATION/DISTRIBUTION and gated by a live honeypot check. The read for trading agents, not a prediction.
news_signal — Recent news headlines + heuristic bull/bear sentiment for a ticker or topic.
edgar_filings — Latest SEC EDGAR filings (10-K/10-Q/8-K) for a US ticker or CIK, with document links.

infer — Chat completions on open models, relayed to openrouter.ai (a hosted model API); gate402 runs no GPUs for this. The 402 quote prices your prompt plus max_tokens, and you pay that quote: unused tokens are not refunded. Per 1M tokens, input / output: llama-3.1-8b $0.08 / $0.128, llama-3.1-70b $0.64 / $0.96, qwen-2.5-7b $0.08 / $0.128, mistral-small $0.08 / $0.128. Minimum $0.001 a call. Returns a signed usage receipt (verify free at /v1/receipt/verify).
vectorcache — Cache for repeated queries: an exact match first, then the closest stored text at 0.88 cosine similarity or higher. It hashes words and character trigrams rather than running a model, so the same question in other words is a miss. The response reports the similarity and the lookup time.
demand_intel — Anonymized agent demand intelligence: top unmatched API paths, challenge vs serve conversion by tool, last-seen timestamps. For x402 API builders: what agents already try to buy.
receipt_attest — Live delivery attestation: did this Gate402 route return HTTP 200 after payment in the last N minutes? Ledger-based post-payment proof, not an uptime probe.
uploadfix — Fix a rejected upload: convert HEIC, hit size/format/dimension requirements for DMV, passport, LinkedIn, or custom limits. $1 per file.
heic_to_jpg — Convert an iPhone HEIC/HEIF photo to JPG that websites accept. $1 per file.
under_mb — Shrink a file under a max size (e.g. 5 MB). Images are recompressed. $1 per file.
image_fit — Resize any image to exact pixel dimensions and optional max filesize. $1 per file.
metadata_strip — Strip EXIF/GPS and other privacy-leaking image metadata. $1 per file.
json_repair — Repair malformed or LLM-mangled JSON into valid JSON. $1 per call.
csv_json — Convert CSV → JSON or JSON → CSV with cleanup. $1 per call.
contract_scan — Full smart-contract risk scorecard for a Base token/contract: risk 0–100, honeypot, taxes, liquidity, holders. $1 per scan.
abi_decode — Decode calldata or ABI for a Base contract into a human-readable signature and args. $1 per call.
photo_to_pdf — Turn phone photos of pages into a clean multi-page PDF. $1 per job.
bg_remove — Remove image background and return a transparent PNG. $1 per image.
video_under_mb — Compress a video under a max filesize (MP4/H.264). $1 per file.
site_screenshot — Capture desktop and/or mobile screenshots of a public URL. $1 per request.
ocr_structured — OCR a receipt/ID/form image or PDF and return structured JSON fields. $1 per document.
ats_resume — Score a resume against a job description and return an ATS-optimized PDF. $1 per run.
invoice_pro — Turn a screenshot, email, CSV, or rough invoice text into a professional PDF invoice. $1 per document.
pdf_fillable — Analyze a flat PDF and return a fillable PDF with AcroForm text fields. $1 per document.
pdf_a11y — Basic PDF accessibility remediation: title/language metadata, outline, and accessibility report. $1 per document.
doc_checker — Check a file against upload requirements (format, max MB, dimensions) and return a pass/fail report. $1 per check.
jwt_decode — Decode a JWT into its header and payload claims, with human-readable timestamps. Signature is NOT verified. $1 per call.
base64 — Base64 encode or decode UTF-8 text. $1 per call.
hash — Compute MD5, SHA-1, SHA-256, and SHA-512 hashes of a text string. $1 per call.
uuid — Generate random v4 UUIDs (1–100 at a time). $1 per call.
cron_explain — Explain a 5-field cron expression in plain English. $1 per call.
unix_time — Convert between a Unix timestamp and a human-readable date, both directions. Empty input returns the current time. $1 per call.
url_encode — URL-encode or decode text (URI component or full URI). $1 per call.
qr_code — Generate a QR code (PNG or SVG) for a URL or text. $1 per call.
regex_test — Test a regular expression against text: matches, capture groups, and positions. Patterns with nested quantifiers are refused, and a pattern that runs longer than 1 s on the text is stopped with an error. $1 per call.
