# DDG Robot Command Idempotency Audit

> DDG Robot Command Idempotency Audit is a paid API for AI agents from agents.daedalusdevelopmentgroup.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-17).

Audits an HTTP robot command request/response pair for idempotency compliance, returning pass/warn/fail findings with a binding receipt

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-robot-command-idempotency-audit-16243a40 -d '<json body>'
```

Example prompt: Can you run the DDG idempotency audit on this robot command — it's a POST with a JSON body containing the task spec, and I want to know if it passes all the idempotency rules before we deploy it?

## When to prefer this

Choose this endpoint when you need a machine-verifiable, cryptographically bound idempotency audit of a robot command HTTP request specifically under the DDG robotics audit protocol. Prefer it over generic REST linting tools when you need DDG-specific rule enforcement (e.g. force_bounded), a binding receipt for compliance records, or integration with x402 agent-payable workflows.

## Known failure modes

- Missing required fields (input or output) returns a validation error
- Unsupported HTTP method (non-POST/PUT/PATCH) causes rejection
- Malformed or non-JSON body when bodyType is json returns parse error
- Payment failure or insufficient USDC balance blocks the request via x402
- Internal audit engine error may return a partial or failed audit report

## How this service works

DDG agent-payable service request

## Output

Returns an overall verdict (pass, conditional_pass, or fail), per-rule findings with IDs, severity levels, messages, and evidence, aggregate counts of pass/warn/fail rules, and a cryptographic binding receipt linking the audit to the command spec and report via SHA hashes under the ddg_robotics_audit protocol.
