# Stormap Payment Safety Checker

> Stormap Payment Safety Checker is a paid API for AI agents from stormap.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Checks whether it is safe to pay a given endpoint, seller domain, or wallet address before making a payment, returning a verdict (ok_to_pay, caution, or dont_pay) with supporting signals.

## 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 stormap-payment-safety-checker-74fecb50
```

Example prompt: Before you pay that endpoint, run a safety check on https://api.example.com/x402/v1/generate — I want to make sure the wallet address is legitimate, the price is fair, and the seller domain isn't sketchy.

## When to prefer this

Use this endpoint before any agent-initiated micropayment to an unknown or third-party x402 endpoint, wallet, or seller domain — especially when the agent is operating autonomously and cannot rely on human review. Prefer this over generic WHOIS or domain-age lookups because it combines payment-specific signals (address match, USDC validity, price benchmarking, Bazaar listing) into a single actionable verdict.

## Known failure modes

- Target URL or domain is unreachable or returns no usable data
- Wallet address format is invalid or unrecognized
- Bazaar listing not found for the target endpoint
- Insufficient data to make a confident verdict, resulting in caution by default
- Domain age lookup fails for newly registered or obscure TLDs

## How this service works

Should your agent pay this endpoint, seller or wallet? Verdict (ok_to_pay / caution / dont_pay) from live payment terms, its x402 Bazaar listing and paying wallets, payment-address match, real-USDC check, price vs. similar tools, and seller domain age.

## Output

Returns a verdict of ok_to_pay, caution, or dont_pay along with supporting evidence: live payment terms analysis, x402 Bazaar listing match, payment-address verification, real-USDC check, price comparison against similar tools, and seller domain age.
