# apex-edge Hash Utility

> apex-edge Hash Utility is a paid API for AI agents from apex-edge.pearceshrader.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-10).

Computes a cryptographic hash of provided input data as a paid utility endpoint with x402 micropayment authentication

## Facts

- Endpoint: GET https://apex-edge.pearceshrader.workers.dev/api/v1/util/hash?utm_source=zero.xyz
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-10
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/apex-edge-hash-utility-c34f7aa8
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_cu1QDwJaxUAFk6vnBB9Ek

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 apex-edge-hash-utility-c34f7aa8
```

Example prompt: Hash this string for me using the apex-edge utility: 'user:alice@example.com|timestamp:1718000000|action:purchase' — I need the cryptographic digest to use as an integrity check.

## When to prefer this

Choose this endpoint when you need a pay-per-use, auditable cryptographic hashing service with x402 micropayment support, particularly in agentic workflows where you want per-call billing accountability and an audit trail. Prefer it over free or self-hosted hashing when you need provable, third-party-attested computation with a blockchain-compatible payment layer.

## Known failure modes

- Empty or missing input body returns an error response
- Unsupported algorithm parameter yields a 400-style error
- Payment not provided or x402 handshake fails returns 402 Payment Required
- Malformed JSON request body causes parsing error
- Network timeout on the Cloudflare Worker edge node

## How this service works

x402-paid inference + audit endpoints

## Output

Returns a JSON object containing the computed cryptographic hash digest of the submitted input, typically as a hex-encoded string. The response may include the algorithm used and the resulting hash value suitable for integrity checks, deduplication, or audit logging.
