## 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 primeapi-hash-verify-c8cde1d6 -d '<json body>'
```

Example prompt: Can you verify whether the hash 'e99a18c428cb38d5f260853678922e03' matches the string 'abc123' — I need to confirm the data hasn't been tampered with.

## When to prefer this

Use this endpoint when you need a simple, pay-per-call hash verification without managing API keys or infrastructure. Suitable for agents that occasionally need to verify data integrity as part of a workflow, especially when already operating in a USDC/x402 payment context on Base.

## Known failure modes

- Invalid or malformed hash format returns an error response
- Unsupported hash algorithm results in a failure or unknown result
- Missing query input returns a 400 bad request
- Hash and data mismatch returns a negative verification result
- Service unavailable or timeout on the Vercel deployment

## How this service works

Crypto, AI, Social Media, Finance, Weather, Tools &amp; more. Pay per call in USDC on Base. No API keys.

## Output

Returns a validation result indicating whether the provided hash matches the input data, typically including a boolean match status and possibly the algorithm used or details about the verification outcome.
