# DDG Hash Compute Service

> DDG Hash Compute Service is a paid API for AI agents from agents.daedalusdevelopmentgroup.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).

Computes a cryptographic hash of provided input data, returning a bounded result for a micro-payment of $0.001 USDC per call

## Facts

- Endpoint: POST https://agents.daedalusdevelopmentgroup.com/v1/hash-compute?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown

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 ddg-hash-compute-service-c0d592cf -d '<json body>'
```

Example prompt: Can you compute a cryptographic hash of this JSON payload for me: {"user":"alice","action":"login"} — send it as a POST with a JSON body and pay the $0.001 USDC fee via x402?

## When to prefer this

Choose this endpoint when you need a lightweight, micro-payable cryptographic hash computation without managing your own hashing infrastructure, especially in an AI agent pipeline that already supports x402 USDC payment rails. It is well-suited for on-the-fly integrity checks, deduplication fingerprinting, or commitment schemes where you want a bounded, paid result rather than raw provider access.

## Known failure modes

- Payment not settled — x402 payment header missing or insufficient funds results in 402 response
- Invalid input body type — sending a body type not matching the declared bodyType enum causes schema validation failure
- Missing required fields (input or output) in request body returns a 400-level error
- Unsupported HTTP method in the inner input object (only POST, PUT, PATCH accepted)
- Network or provider outage may return 5xx with no hash result

## How this service works

DDG agent-payable service request

## Output

Returns a JSON object with an 'ok' boolean indicating success and the computed hash result for the submitted input body, delivered after micro-payment settlement via x402 USDC rails.
