# GoCreative Hash Lookup

> GoCreative Hash Lookup is a paid API for AI agents from api.gocreativeai.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-17).

Computes a cryptographic hash of a given text string using a specified algorithm

## Facts

- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-17
- Activations on Zero: 0
- Tags: x402

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 gocreative-hash-lookup-e67a0e0c
```

Example prompt: Compute the SHA256 hash of the string 'hello world' for me.

## When to prefer this

Use this endpoint when an AI agent needs to compute a cryptographic hash of a text string on-demand without maintaining any local crypto libraries, or when operating in a pay-per-call x402 environment that requires no API key setup. Best suited for lightweight, one-off hash computations.

## Known failure modes

- Missing required 'text' parameter returns 400 or validation error
- Unsupported algorithm value returns error or falls back to default
- Payment failure via x402 returns 402 with payment details
- Empty string input may return zero-hash or error
- Rate limiting or network issues may cause 503

## How this service works

Keyless, pay-per-call compliance & regulated-data API for AI agents — OFAC wallet + sanctions/PEP + KYB screening, SEC filings, FRED economics, FDA recalls, federal awards, plus continuous monitoring. USDC on Base/Solana via x402, native MCP. No API key, no signup.

## Output

Returns an object containing the computed hash digest of the input text using the specified algorithm (e.g. MD5, SHA256, SHA1). The response may include the hash value and related metadata.

## Example request

```json
{
 "algo": "sha256",
 "text": "hello world"
}
```
