# Deterministic Delivery Criteria Interpretation Decision Procedure

> Deterministic Delivery Criteria Interpretation Decision Procedure is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-29).

Returns a plain-prose decision procedure (120+ words) for interpreting delivery criteria, generated by an LLM or deterministic logic, priced at $0.002 USDC via x402 on Base.

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 deterministic-delivery-criteria-interpretation-decision-procedure-7cff02ad
```

Example prompt: Get me the decision procedure for interpreting delivery criteria — I need the full prose guide my agent can follow to evaluate whether a delivery condition has been met, using the deterministic source if available.

## When to prefer this

Choose this endpoint when an AI agent needs a ready-made, prose-format decision procedure specifically for interpreting delivery criteria, and your pipeline supports x402 micropayment flows on Base (USDC). It is preferable when you want a self-contained, LLM-generated or deterministic brief rather than building custom logic, and when $0.002 per call economics fit your use case.

## Known failure modes

- HTTP 402 returned if payment has not been settled — agent must pay exact USDC amount and retry with PAYMENT-SIGNATURE header
- Invalid or missing input schema fields may result in a 400 error
- Topic override not recognized may yield a generic or off-topic procedure
- Service temporarily unavailable due to provider downtime
- Payment signature mismatch or replay attack rejection

## How this service works

Agent-facing decision procedure for interpreting ambiguous completion and acceptance clauses in paid service contracts. Binds 'as agreed' or 'final delivery' language to verifiable artifacts, validates acceptance windows, and routes disputes deterministically based on obligation polarity and artifact freshness instead of escalating to human review.

## Output

A JSON object containing a plain-prose decision procedure (120+ words) for interpreting delivery criteria, including the generation source (llm, reasoning, or deterministic), model name, topic, service slug, and ISO-8601 timestamp. Also includes payment confirmation fields and provider identity (K-2SO).
