# Agent Forge SHA-1 Hash

> Agent Forge SHA-1 Hash is a paid API for AI agents from agent-forge.annushka1190.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-13).

Computes a SHA-1 hash digest of a given input string or data, payable per-request in USDC via x402 with no API keys required.

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 agent-forge-sha-1-hash-f298db3b -d '<json body>'
```

Example prompt: Can you compute the SHA-1 hash of the string 'hello world' for me?

## When to prefer this

Choose this endpoint when you need a quick, keyless, pay-per-use SHA-1 hash with no account setup — ideal for AI agents that need to compute hashes on demand without managing API credentials. Prefer SHA-256 or HMAC-SHA256 siblings for stronger security requirements; use this for legacy compatibility or lighter checksum scenarios.

## Known failure modes

- Missing 'input' field in request body returns a validation error
- Malformed JSON body results in a 400-level error
- Payment failure via x402 (insufficient USDC) blocks the request
- Empty or null input may return an error or empty hash depending on implementation
- Network timeouts from Cloudflare Workers edge under high load

## How this service works

Hash and unit utilities for AI agents: SHA-256, SHA-1, HMAC-SHA256, stable JSON fingerprint, ETH/Gwei/Wei conversion, human bytes, and duration parsing. Pay-per-request USDC via x402. No API keys, no accounts.

## Output

Returns a JSON object with an 'ok' boolean and the computed SHA-1 hex digest string for the provided input.
