# Creator Desk SHA256 Hash Utility

> Creator Desk SHA256 Hash Utility is a paid API for AI agents from creator-desk-x402-isolated.onrender.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Computes a SHA256 cryptographic hash of a given input value via a micropayment-gated API endpoint

## Facts

- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-12

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 creator-desk-sha256-hash-utility-dc32bb23 -d '<json body>'
```

Example prompt: Can you compute the SHA256 hash of the string 'hello world' for me?

## When to prefer this

Use this endpoint when your agent workflow needs a quick, serverless SHA256 hash computation without standing up local crypto libraries, or when you require a micropayment-auditable hash operation (e.g. for on-chain provenance or billing-tracked data pipelines). It is purpose-built for autonomous agents using the x402 payment protocol.

## Known failure modes

- Missing or empty 'value' field returns an error or undefined result
- Malformed JSON body causes a 400-level response
- Payment not included or invalid causes a 402 Payment Required response
- Network or cold-start latency on Render free tier may cause timeouts
- Unsupported option keys in the 'options' object may be silently ignored or cause errors

## How this service works

Machine-callable x402-paid utilities for autonomous agents.

## Output

Returns a JSON object containing a 'result' field with the SHA256 hash of the input value and an 'operation' field confirming the operation was 'sha256'.
