# DDG Trust Check

> DDG Trust Check is a paid API for AI agents from agents.daedalusdevelopmentgroup.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-02).

Submits an HTTP request payload to the DDG trust verification endpoint, returning a simple ok/not-ok trust result for agent-payable workflows.

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-trust-check-1c443e01 -d '<json body>'
```

Example prompt: Run a DDG trust check on this JSON POST request body so we know whether to proceed with the workflow — the body is {"userId": "abc123", "action": "transfer"} and the body type is JSON.

## When to prefer this

Use this endpoint when you need a lightweight, machine-payable trust verification step before executing sensitive agent actions or workflows. It is particularly suited for agentic pipelines that require a programmatic trust gate without heavy identity infrastructure, and when operating within the x402 payment protocol ecosystem.

## Known failure modes

- Missing required fields ('input' or 'output') returns a validation error
- Unsupported HTTP method (not POST/PUT/PATCH) causes rejection
- Invalid bodyType enum value triggers schema error
- Payment failure via x402 rails results in 402 Payment Required response
- Malformed JSON body returns a parsing error
- Network timeout if the DDG backend is unreachable

## How this service works
