Base mainnet USDC. The 402 challenge is the price quote — your agent sees exactly what it pays before paying.
| Endpoint | What the agent gets | Price |
|---|---|---|
| agents.thirdmade.net/scrape | One scraped page result as clean JSON (figranium-backed when configured) | $0.01 |
| agents.thirdmade.net/ | Service health + capabilities manifest | free |
Protocol flow: call → 402 challenge → settle USDC on Base → same request with X-PAYMENT header → 200 + result. Standard x402; any compliant client works.
28 probe endpoints are rolling out across five verified demand categories. Each is a cheap, honest, schema-described API. The shelf grows weekly; this table updates as routes go live.
/AGENTS.md and /llms.txt list every endpoint, schema, and price. MCP tools mirror every route.The build methodology is public: verify-loop — an agent + messy-data pipeline with spend/dup guards and an eval loop, runnable offline.
