# DeFi Shield API Endpoint Trust Auditor

> DeFi Shield API Endpoint Trust Auditor is a paid API for AI agents from defi-shield-hazel.vercel.app, paid per call via x402, $0.5/call, status unknown (last checked 2026-09-14).

Audits an API endpoint URL for availability, latency, response validity, schema consistency, and produces a trust score with a list of detected issues

## Facts

- Endpoint: POST https://defi-shield-hazel.vercel.app/api/trust/endpoint-audit
- Price: $0.5/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/defi-shield-hazel-vercel-app-149b2c39
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_vZ7DIO7NqXkXe5ERIF_z-

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 defi-shield-hazel-vercel-app-149b2c39 -d '<json body>'
```

Example prompt: Can you run a full trust audit on https://api.example.com/v1/data and tell me whether it's reachable, how fast it responds, and what its trust score and any issues are?

## When to prefer this

Use this endpoint when an AI agent needs to programmatically verify whether a third-party or unknown API URL is trustworthy, live, and returning consistent responses before relying on it — especially useful in agentic workflows where a downstream API must be vetted before use, or when building trust registries for API integrations.

## Known failure modes

- Target endpoint is unreachable — audit returns available:false, trustScore near 0, and issue list noting unreachability
- Target endpoint returns unexpected schema — schemaConsistent:false flagged in response
- Network timeout on probe — high latencyMs, responseValid:false
- Malformed or invalid URL provided in request body — likely 400 or validation error response
- Target endpoint is slow but technically alive — low trust score with latency-related issues listed

## Output

Returns a JSON object with the audited URL, a trust score (0-100), availability boolean, latency in milliseconds, response validity flag, schema consistency flag, a list of detected issues, a timestamp, and any historical comparison data.
