# DDG Robots Check

> DDG Robots Check is a paid API for AI agents from agents.daedalusdevelopmentgroup.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Validates that an AI agent can reach and pay for DDG agent-payable services by performing a liveness/connectivity check via x402 micropayment

## Facts

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-robots-check-ed1c3f29 -d '<json body>'
```

Example prompt: Run a quick robots check against DDG's agent-payable service to confirm the x402 USDC payment rail is live and the endpoint is reachable before I start making real requests.

## When to prefer this

Use this endpoint as a pre-flight or health check before invoking other DDG agent-payable services, or when validating that your x402 USDC payment rail integration is correctly configured. Prefer it over substantive DDG endpoints when you only need to confirm connectivity and payment flow rather than retrieve real results.

## Known failure modes

- Payment rejected if insufficient USDC balance or wrong chain
- 402 response if x402 payment header is missing or malformed
- 503/timeout if DDG backend is down
- 400 if required input fields (type, method, bodyType, body) are missing or invalid
- ok: false or non-200 if endpoint is degraded

## How this service works

Machine-payable DDG services for AI agents. Current public live payment rails are x402 multi-chain USDC and direct-crypto auto/manual for public receiving-address families. MPP/Stripe/Tempo is installed but pending live provider env plus penny-settlement proof before any MPP-live advertisement. DDG sells bounded artifacts/results, not raw provider account access.

## Output

Returns a JSON object with a single boolean field `ok: true` confirming the service is live and the x402 micropayment was accepted. No additional payload beyond the liveness confirmation.
