# DDG Tine Replay Verdict

> DDG Tine Replay Verdict is a paid API for AI agents from agents.daedalusdevelopmentgroup.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-20).

Compares original and replay execution artifacts to produce per-step digest identity, drift detection, cost delta, and an equivalence verdict (re_derives, diverges, or inconclusive)

## 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-replay-verdict-aea8d307 -d '<json body>'
```

Example prompt: Compare my original tine run artifact and its replay — give me the per-step digests, any drift, cost delta, and tell me whether the replay re_derives, diverges, or is inconclusive.

## When to prefer this

Use this endpoint when you need a structured, per-step equivalence verdict between an original execution and its replay — specifically for tine-format artifacts produced by DDG's execution framework. Prefer this over manual log diffing when you need a machine-readable drift set, cost delta, and a formal re_derives/diverges/inconclusive verdict suitable for CI gates or audit trails.

## Known failure modes

- Missing or malformed original/replay artifact bodies returns a 400 validation error
- Artifacts with incompatible schema versions may yield an inconclusive verdict
- Payment failure via x402 results in 402 Payment Required before processing
- Incomplete step traces may cause partial drift sets with inconclusive verdict
- Large artifact bodies may time out if execution trace is too deep

## How this service works

Given original and replay artifacts: per-step digest identity, drift set, cost delta, and a re_derives | diverges | inconclusive equivalence verdict.

## Output

Returns per-step digest identity for each execution step, a drift set identifying where original and replay diverged, a cost delta between the two runs, and a top-level equivalence verdict of either re_derives (fully equivalent), diverges (meaningful differences detected), or inconclusive (insufficient data to determine).
