What it does

Monitor recurring CSV feeds for schema drift and enforce optional saved import-validation rules at $0.005 USDC per update. Reuse a private monitor_token while your scheduler sends successive snapshots. Retains aggregate profile and contract metadata for up to 30 days, never raw rows or cell values. Does not poll URLs or send webhooks.

Use with an agent

1. Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
2. Inspect. Fetch /resources/79806.json for the price and payment options.
3. Pay. Call GET https://agent-evidence-extractor.defcronyke.workers.dev/v1/csv-monitor. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
4. Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.

For humans

You don't need an account or an API key; you need a wallet holding a small amount of USDC on Base, Arbitrum One, Polygon, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.

# -> 402 Payment Required, accepts[] lists how to pay
# retry with a PAYMENT-SIGNATURE (or PAYMENT header) once paid

const res = await fetch("https://agent-evidence-extractor.defcronyke.workers.dev/v1/csv-monitor");
