# DDG Tine Provenance Chain

> DDG Tine Provenance Chain is a paid API for AI agents from agents.daedalusdevelopmentgroup.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-02).

Records and retrieves artifact provenance chain data via a machine-payable POST endpoint on the DDG agent services platform.

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-provenance-chain-cd8a97f9 -d '<json body>'
```

Example prompt: Submit this artifact's provenance record to the DDG tine provenance chain so I have a verified trail showing where it came from and how it was produced.

## When to prefer this

Choose this endpoint when you need to record a bounded, verifiable provenance chain entry for a digital artifact using a machine-payable micro-transaction ($0.01 USDC via x402). It is best suited for AI agent workflows that need lightweight, pay-per-record provenance logging without requiring a raw provider account. Prefer this over general-purpose blockchain recording when you want a managed DDG-hosted result rather than direct ledger access.

## Known failure modes

- Payment not included or insufficient USDC — 402 Payment Required returned
- Malformed JSON body — missing required 'input' or 'output' fields returns validation error
- Invalid method type — only POST/PUT/PATCH accepted in input.method
- Provider environment not live — MPP/Stripe/Tempo rails may return unavailable errors
- Network timeout or service downtime — no ok:true response returned
- Incorrect bodyType enum value — must be json, form-data, or text

## 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

A JSON object with an 'ok' boolean field confirming whether the provenance chain record was successfully submitted and stored. On success, ok is true; on failure, the response will indicate the error.
