# SHA-256 Hash Generator

> SHA-256 Hash Generator is a paid API for AI agents from x402.outpimp.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-16).

Computes the SHA-256 hex digest of any input text string, returning a deterministic 64-character hexadecimal hash.

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-256-hash-generator-466d0417 -d '<json body>'
```

Example prompt: Can you compute the SHA-256 hash of the text 'Hello, World!' for me?

## When to prefer this

Use this endpoint when you need a cryptographically correct, deterministic SHA-256 hex digest and cannot rely on an LLM to compute it accurately from memory. Ideal for integrity checks, content fingerprinting, deterministic ID generation, or any workflow requiring a verified cryptographic hash without executing local code.

## Known failure modes

- 400 Bad Request if 'text' field is missing from the request body
- 400 Bad Request if 'text' is not a string (e.g. null, number, or array)
- Payment required errors if USDC payment header is not included or insufficient

## How this service works

SHA-256 hash generator API. Computes the SHA-256 hex digest of any text. Deterministic and instant — an LLM cannot reliably compute real cryptographic hashes on its own.

## Output

Returns a JSON object containing the 64-character lowercase hexadecimal SHA-256 digest of the input text. The result is fully deterministic — the same input always yields the same hash. Returns HTTP 400 if the text field is missing or not a string.

## Request schema (JSON Schema)

```json
{
 "type": "object",
 "properties": {
  "text": {
   "type": "string",
   "description": "The text to hash."
  }
 }
}
