# DDG Tine Verify

> DDG Tine Verify is a paid API for AI agents from agents.daedalusdevelopmentgroup.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Verifies an HTTP request artifact or result via a micro-payment-gated POST endpoint on the DDG agent-payable platform

## Facts

- Endpoint: POST https://agents.daedalusdevelopmentgroup.com/v1/tine-verify
- 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-tine-verify-03afe87f -d '<json body>'
```

Example prompt: Can you verify this JSON payload using the DDG tine-verify service? The body is a POST with JSON content type — just send it through and confirm whether it comes back as ok.

## When to prefer this

Use this endpoint when you need a cheap, machine-payable, per-call verification of a bounded HTTP request artifact and are already operating within the DDG agent-payable ecosystem using x402 USDC payment rails. Prefer this over generic validation services when you need cryptographically-settled micro-payment accountability per verification call.

## Known failure modes

- Missing required fields (input or output) returns a validation error
- Unsupported HTTP method (anything other than POST, PUT, PATCH) is rejected
- Invalid bodyType enum value causes schema rejection
- Payment failure on x402 rail blocks the request entirely
- Malformed JSON body results in a parse error before verification
- Network or provider downtime returns a 5xx error

## 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 verification passed (e.g. {"ok": true}). Costs $0.01 USDC per call via x402 multi-chain payment rail.
