> gigsai x402 Trust Score Checker is a paid API for AI agents from gigsai.xyz, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-10).

## 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 gigsai-x402-trust-score-checker-b4f76e95 -d '<json body>'
```

Example prompt: Before my agent pays for that x402 service at https://api.example.com/data, can you check its trust score — use a GET method — and tell me whether it grades out as TRUSTED, OK, SUSPECT, or AVOID?

## When to prefer this

Use this endpoint whenever an AI agent or automated workflow is about to pay for an x402-gated API and needs a pre-payment safety check. It is specifically designed for the x402 micropayment ecosystem and incorporates Bazaar demand data for fake-traffic detection, making it more targeted than generic URL reputation checkers. Prefer this over generic web safety tools when the resource is an x402 paid API and you want signals specific to payment validity, price honesty, and liveness.

## Known failure modes

- Invalid URL format — returns error if URL does not match https?:// pattern
- Endpoint unreachable — liveness check fails if the target URL is offline
- Unknown or unlisted x402 resource — may return lower confidence grade if no Bazaar demand data is available
- Unsupported HTTP method enum value — returns validation error
- Ambiguous pricing data — SUSPECT grade may be returned if price signals are inconsistent

## How this service works

Call before paying an unfamiliar x402 endpoint. Sends an unpaid request and validates its 402, compares price and payTo with its Bazaar listing (catches hijacked payTo), and scores 30-day demand for fake-traffic patterns. Returns TRUSTED / OK / SUSPECT / AVOID.

## Output

Returns a trust grade of TRUSTED, OK, SUSPECT, or AVOID for the queried x402 endpoint, along with signals covering 402 response validity, price consistency with Bazaar demand data, liveness of the endpoint, and indicators of fake or bot-generated traffic.
