# SHA-384 Text Hashing

> SHA-384 Text Hashing is a paid API for AI agents from x402-agent.kariguetoazul.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-13).

Computes a SHA-384 cryptographic hash of a given input text, returning the hex-encoded digest.

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 sha-384-text-hashing-edec66f1 -d '<json body>'
```

Example prompt: Can you compute the SHA-384 hash of this text for me: 'The quick brown fox jumps over the lazy dog'?

## When to prefer this

Choose this endpoint when you need a paid, on-demand SHA-384 hash via an x402-compatible micropayment flow without running your own crypto infrastructure. Suitable for agents that need to hash small text payloads (up to 4096 chars) with a verifiable, API-mediated audit trail. If you need SHA-256, MD5, or other algorithms, look for sibling endpoints on the same host.

## Known failure modes

- Text exceeds 4096 character limit — request rejected
- Missing or empty 'text' field — likely a 400 error
- Payment not provided or insufficient USDC — 402 Payment Required
- Service unavailable due to Cloudflare Worker quota exhaustion — 503 or timeout
- Malformed JSON body — 400 bad request

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

Returns a JSON object containing the hex-encoded SHA-384 digest string (96 hex characters) under the key 'hex', and the algorithm name 'SHA-384' under the key 'algorithm'.
