x402_diagnose
Diagnose an x402 endpoint ($0.01 via x402)
Paid ($0.01 USDC via x402 on Base or Solana): diagnose an x402 endpoint the way a paying agent would, without paying it: the 402 challenge format, every accepts[] option, the resource URL, Solana settlement readiness, which wallets can pay, Bazaar/OpenAPI discovery and the browser paywall. Returns every check with pass/warn/fail and a fix hint. Same as GET /api/v1/diagnose. The answer carries a signed receipt (EIP-191, bound to your arguments) that proves later which verdict you got.

x402_fix
Fix plan for an x402 endpoint ($0.05 via x402)
Paid ($0.05 USDC via x402 on Base or Solana): diagnoses your x402 endpoint, then returns per problem the concrete change as code for your stack (express, next, hono, node, python, generic), filled in with your own payTo, amount, network and route. Same as GET /api/v1/fix. The answer carries a signed receipt (EIP-191, bound to your arguments) that proves later which verdict you got.

x402_preflight
Check an x402 endpoint before paying it ($0.001 via x402)
Paid ($0.001 USDC via x402 on Base or Solana): call this before your agent pays an x402 endpoint. Returns go, caution or no_go, the recommended payment option, and why: payment would fail, over your budget (max_usd), price above what is advertised, not HTTPS, unknown token, its 30-day track record. Never pays the endpoint. Same as GET /api/v1/preflight. The answer carries a signed receipt (EIP-191, bound to your arguments) that proves later which verdict you got.

x402_preflight_batch
Check up to 10 x402 endpoints before paying ($0.005 via x402)
Paid ($0.005 USDC via x402 on Base or Solana): the pre-payment check for up to 10 x402 endpoints at once. Per endpoint go, caution or no_go, the recommended payment option and why, plus totals. For marketplaces and agents that weigh several services. Never pays the endpoints. Same as GET /api/v1/preflight/batch. The answer carries a signed receipt (EIP-191, bound to your arguments) that proves later which verdict you got.

x402_preflight_deep
Deep check of an x402 endpoint before an expensive payment ($0.01 via x402)
Paid ($0.01 USDC via x402 on Base or Solana): for expensive calls. The pre-payment verdict (go, caution or no_go) plus the full diagnosis, the 30-day history per day, how reliable the seller's other endpoints are and whether the endpoint moved domains. Never pays the endpoint. Same as GET /api/v1/preflight/deep. The answer carries a signed receipt (EIP-191, bound to your arguments) that proves later which verdict you got.
