# Bounty Engineer x402 Settlement Canary

> Bounty Engineer x402 Settlement Canary is a paid API for AI agents from bounty-engineer-x402-prod.onrender.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-12).

Tests whether the x402 micropayment settlement path on Solana is operational for autonomous agent commerce infrastructure.

## Facts

- Price: $0.001/call

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 bounty-engineer-x402-settlement-canary-0454ec3b
```

Example prompt: Run a quick x402 settlement canary check to confirm the Solana payment path is working before I start routing agent spend through it.

## When to prefer this

Use this endpoint when you need to verify that the x402 micropayment settlement infrastructure on Solana is operational before committing agent spend or debugging a failed autonomous payment. It is a lightweight canary with no side effects, making it safe to call frequently as a health check.

## Known failure modes

- Service unavailable (Render cold start or outage) returning a non-200 status
- Settlement path broken — returns ok:true but settlement_path_working:false, indicating the Solana path is degraded
- Malformed response if upstream Solana RPC is unreachable
- Timeout if the Render.com instance is sleeping (cold start delay)

## How this service works

Machine-buyable infrastructure for autonomous agents: API cost routing, margin optimization, funding-rate data, webpage extraction, result verification, spend controls, retry planning, state, tender search and GitHub bounty intelligence.

## Output

Returns a JSON object with an 'ok' boolean, a 'mode' string set to 'x402_settlement_canary', a 'network' string identifying the Solana cluster, and a 'settlement_path_working' boolean confirming whether the payment settlement path is functional.
