# HirePulse Pre-Purchase Merchant Trust Check (verify-merchant)

> HirePulse Pre-Purchase Merchant Trust Check (verify-merchant) is a paid API for AI agents from gethirepulse.xyz, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-22).

## 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 hirepulse-pre-purchase-merchant-trust-check-verify-merchant-153b7ee6 -d '<json body>'
```

Example prompt: Before my agent pays, can you run a HirePulse merchant trust check on https://api.somevendor.com/v1/data to see if it's safe — scan it for x402 compliance, poisoning risks, and any red flags without actually authorizing payment?

## When to prefer this

Use this endpoint when an AI agent is about to make its first payment to an unknown or unverified x402 merchant and needs a pre-authorization trust signal. Prefer this over generic URL scanners because it is specifically tuned for x402 protocol compliance, agentic prompt-poisoning attack detection, and MCP merchant patterns — concerns that general web security scanners don't address.

## Known failure modes

- Invalid or unreachable target_url returns empty result with no charge
- Non-HTTPS URLs or malformed URLs may be rejected
- Private or internal endpoints that cannot be scanned publicly will return no data
- Rate limit after 5 free calls per day; subsequent calls billed at $0.005 USDC
- Target endpoint actively blocking scanners may yield incomplete results
