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 scriptmasterlabs-mcp-x402-hunter-report-submission-23462dce -d '<json body>'
```

Example prompt: Submit a hunter report for the /x402/sec-8k endpoint — it worked fine, took about 320 milliseconds, usefulness was 4 out of 5, and the settlement transaction was 0xabc123def456, with a note that the data was current and well-structured.

## When to prefer this

Use this endpoint when you need to programmatically submit quality, latency, and outcome feedback for a specific x402 API call you just made on the ScriptMasterLabs marketplace — particularly after testing or using pay-per-call endpoints like /x402/sec-8k, /x402/gas-tracker, or /x402/pha-lookup and want to record the settlement transaction and rate usefulness.

## Known failure modes

- Payment not provided — returns HTTP 402 unless X-Api-Market-Key or x402 payment header is supplied
- Invalid or missing required fields may result in a 400 error or silent failure
- Settlement transaction hash not recognized or malformed
- Latency or usefulness values out of expected integer range
- Service unavailable on free Render hosting tier (cold start delays or downtime)

## How this service works

Pay-per-call crypto, RWA, federal, SEC, Section 8/HUD housing, and compliance APIs via x402. Primary: USDC on Base (eip155:8453). Also accepts Global Dollar (USDG) on Robinhood Chain (eip155:4663) via sovereign X-PAYMENT-TX. Hyphen routes only (e.g. /x402/gas-tracker, /x402/pha-lookup, /x402/sec-8k). MARKETPLACE REVIEW: use free /x402/playground/* (no key, no payment). Production /x402/* returns 402 unless paid via x402 or X-Api-Market-Key / X-API-Key from seller dashboard.

## Output

Returns an empty example object as acknowledgement that the hunter report was received and stored; no detailed payload is returned beyond confirmation.
