Agent-readiness audit of a website: AI bots allowed in robots.txt? main content extractable? llms.txt, sitemap, structured data, OpenAPI/MCP/x402? Score 0-100 with a fix list.

For sellers: zero-spend audit of your x402 endpoint. Score 0-100 and a fix list: 402 validity, latency, payTo, x402 v2, description, Bazaar discovery metadata, Agentic Market listing.

Any URL to clean Markdown plus provenance: title, author, published date, canonical URL, retrieval time and SHA-256 of the fetched bytes, so you can cite it.

x402 market intelligence from the full Agentic Market catalog (31k endpoints) plus our liveness scan: where buyers pay, crowded vs underserved niches, top sellers, dead share. Optional ?q= filter.

Check an x402 endpoint before paying it: alive? correctly gated? price, network, latency. ~11% of listed endpoints we sampled were dead.

Pre-flight up to 10 x402 endpoints in one call and get them ranked: cheapest live, payable option first.
