Pay-per-call web services for AI agents (70 tools: scraping, screenshots, PDF, OCR, search, news, weather, prices, validation, codes). Paid per request with USDC on Base or Solana via x402. No account or API key.
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":"agentsvc-io-agentsvc-io","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
