What it does

Invoice or receipt PDF OCR to structured JSON for $0.01 USDC on Base, Arbitrum, or Polygon. Extract header fields and up to ten line items from public HTTPS PDF URLs or unencrypted Base64 PDFs up to two pages and 2 MiB. URL redirects and size are bounded; private/local hosts are rejected. Two gpt-6-luna medium-effort calls; quotes are checked against generated OCR text, not PDF bytes. Review against the original PDF.

Use with an agent

Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
Inspect. Fetch /resources/79694.json for the price and payment options.
Pay. Call GET https://agent-evidence-extractor.defcronyke.workers.dev/v1/invoice-pdf-parse. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.

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.
