# TinyData API — Hash Endpoint

> TinyData API — Hash Endpoint is a paid API for AI agents from cleanrows-api.lyra-lavende-7298.chatgpt.site, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-22).

Computes SHA-256, SHA-512, or HMAC-SHA-256 cryptographic hashes of one or more text strings in a single API call

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 tinydata-api-hash-endpoint-d60f1954 -d '<json body>'
```

Example prompt: Hash the text 'hello world' using SHA-256 and give me the hex digest.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use cryptographic hashing service without standing up your own infrastructure — especially for SHA-256, SHA-512, or HMAC-SHA-256 on single strings or small batches up to 500 items, and when operating in a USDC micropayment (x402) environment on Polygon or Base.

## Known failure modes

- Missing required 'algorithm' field returns a validation error
- HMAC-SHA-256 requested without providing 'key' field causes an error
- Batch array exceeds 500 items may be rejected
- Invalid algorithm enum value returns a schema error
- Payment failure or insufficient USDC balance blocks request execution

## How this service works

Hash text, encode or decode Base64, and clean CSV. Pay $0.001–$0.01 per successful request in USDC on Polygon via x402.

## Output

Returns a JSON object with ok:true, the algorithm used, and either a single hex-encoded hash string (for single input) or an ordered array of hex-encoded hashes (for batch input), plus the count of items processed.
