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 apexapi-hash-verify-2953a0bf -d '<json body>'
```

Example prompt: Can you verify whether the SHA256 hash 'e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855' matches the string 'hello world'?

## When to prefer this

Use this endpoint when you need to verify data integrity by checking whether a hash matches expected input — such as confirming file checksums, validating password hashes, or detecting data tampering. Prefer this over manual computation when you need a pay-per-call, no-API-key solution via USDC on Base.

## Known failure modes

- Invalid or malformed hash string returns error
- Unsupported hash algorithm returns error
- Missing required input fields returns 400-style error
- Hash format mismatch causes false negative verification
- Service unavailable returns 5xx error
- Payment failure via x402 prevents call execution

## 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 details about the hash algorithm used.
