# Beggar Bot x402 Seller Health Check

> 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.

## Facts

- Price: $0.02/call
- Payment: x402

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability beggar-bot-x402-seller-health-check-b3c4e93b
```

Example prompt: Can you run a health check on the x402 seller at https://example.com/paid-resource and tell me if it's reachable, TLS is valid, the schema looks correct, and what payTo address and price it's advertising?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
