validate_x402_endpoint

Active

declared in 0.1.0

FREE utility for any agent or seller: checks whether an x402-payable HTTPS endpoint is configured to be indexed by the Coinbase x402 Bazaar. Probes the URL live via CDP's read-only validator (no payment is made, nothing is indexed) and returns per-check preflight results (returns_402, x402 version, bazaar extension, crawlability) plus the simulated accepted/rejected verdict and current index status. Common silent killers it catches: serving x402 v1 (rejected outright), and a bare resource URL that returns 400 instead of 402 (the crawler probes WITHOUT query params). If the endpoint is rejected — or doesn't exist yet — the $99 Bazaar Listing Package does it end-to-end: stack-specific v2 kit, validator loop, we fire the indexing settlement, receipt. Agent wallets buy at https://mudko.com/api/x402/bazaar-listing (x402, USDC on Base); humans pay by card at https://buy.stripe.com/14A9AScmb0OycDk7O28so01; it's included FREE with any engagement (create_bazaar_listing). Exotic stacks: request_quote with a BAZAAR LISTING description.
