# DDG URL Status Checker

> DDG URL Status Checker is a paid API for AI agents from agents.daedalusdevelopmentgroup.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Checks the HTTP status and availability of a given URL, returning a simple ok/not-ok result

## Facts

- Endpoint: POST https://agents.daedalusdevelopmentgroup.com/v1/url-status
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/ddg-url-status-checker-a73d4451
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_nh-7AwVum3Gqm5weYbcGb

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-url-status-checker-a73d4451 -d '<json body>'
```

Example prompt: Can you check if https://example.com/api/health is currently up and responding — send it as a POST with a JSON body?

## When to prefer this

Choose this endpoint when you need a lightweight, paid-per-call URL availability check via the x402 micropayment protocol without needing full uptime monitoring infrastructure. It is ideal for one-off or agent-driven pre-flight checks where you want a bounded result artifact rather than raw HTTP access or a persistent monitoring subscription.

## Known failure modes

- Target URL is unreachable or times out — ok:false or error response
- Invalid or malformed URL provided — request rejected
- Payment not settled via x402 — 402 Payment Required returned before processing
- Body type mismatch with actual content — may cause unexpected probe behavior
- Method not allowed by target server — probe may return non-2xx but still report reachability

## 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 an 'ok' boolean field indicating whether the target URL responded successfully. A true value means the URL is reachable and returned a valid response; false or an error indicates the URL is down or unreachable.
