Beggar Bot x402 Seller Health Check
x402
Beggar Bot x402 Seller Health Check is a paid API for AI agents from beggar-bot-demand.beggarbot.workers.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-11-04).
Checks whether a given x402 seller endpoint is live and correctly configured by fetching its well-known manifest and unpaid 402 challenge, then reporting reachability, TLS, schema validity, network, asset, payTo address, price, and latency.

How this service works
Paid: /v1/verify, /v1/risk, /v1/receipt cost $0.01 USDC per call on Base mainnet via x402 (payTo 0x719227f384b66BFEF00093D6d8d32fA9dC2B40e7); utilities analyze Base mainnet (USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) by default, network=base-sepolia optional; /v1/receipt/verify and discovery files are free. Operator: Beggar Bot.
Output
A structured JSON report containing: reachability status (true/false), TLS validity, schema compliance of the x402 manifest, network and asset details, payTo wallet address, price denomination, and round-trip latency in milliseconds.
Example use cases
Pre-payment seller validation
“Before I pay, check if the x402 endpoint at https://api.someservice.xyz/v1/data is actually reachable and has a valid manifest — I want to know its payTo address, the asset it accepts, and the price it's charging.”
Debugging a broken x402 integration
“My x402 seller at https://mypaidapi.com/resource keeps failing — can you probe it and tell me whether the 402 challenge is being served correctly, if TLS is OK, and what the schema validation says?”
Monitoring x402 endpoint latency
“Run a live health check on https://commerce.example.com/premium-feed and report back the latency, whether it's reachable, and if the well-known x402 manifest is schema-compliant.”
Technical details
Endpoint
GEThttps://beggar-bot-demand.beggarbot.workers.dev/v1/seller-health?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to pre-validate an x402 seller before committing a payment, debug a misconfigured x402 resource, or monitor x402 endpoints for uptime and correctness. It is SSRF-safe and performs no on-chain reads, making it suitable for automated agent workflows. Prefer this over manual inspection when you need structured, machine-readable health data including payTo, asset, network, and latency in a single call.
Side effects
- Seller URL is unreachable — endpoint returns reachable: false with connection error details
- TLS certificate is invalid or expired — reported in TLS field
- x402 manifest schema is malformed or missing required fields — schema OK: false
- SSRF-blocked URL (private IP, localhost) — request rejected before fetch
- Seller returns unexpected HTTP status instead of 402 challenge — reported as challenge failure
- Malformed or missing /.well-known/x402(.json) — schema validation fails
