## 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 refund-and-withdrawal-window-enforcement-decision-procedure-960bd123
```

Example prompt: I paid merchant XYZ via x402 three days ago and their refund policy says I have 7 days to claim with a receipt — can you check the current time and my payment receipt and tell me whether I should submit the refund claim now or wait, and what evidence I need to include?

## When to prefer this

Use this endpoint when an autonomous agent needs to make a time-sensitive decision about whether to submit a refund claim, wait for a merchant SLA to elapse, or exercise cancellation rights — specifically in x402 payment contexts where policy windows, evidence requirements, and fee schedules must be evaluated against real-time clock state. Prefer this over general legal or policy lookup endpoints when the decision must be action-ranked and agent-executable.

## Known failure modes

- Missing or malformed payment receipt prevents eligibility computation
- Clock state not provided causes inability to assess window timing
- Merchant policy terms are ambiguous or incomplete, reducing decision confidence
- Payment not confirmed results in 402 response requiring x402 payment
- Topic override not recognized returns default procedure
- LLM generation failure may result in empty or null brief field

## How this service works

Decision procedure for an autonomous agent enforcing refund eligibility and withdrawal processing windows against a merchant. Inputs: merchant refund policy (window length, conditions, evidence required), withdrawal terms (processing time, fee schedule, cancellation rights), payment rail receipts, and the current clock state. Outputs a ranked action: claim-within-window (submit refund with required evidence and receipt chain), wait-and-recheck (window still open, merchant SLA not yet breached),

## Output

A structured response containing a ranked action recommendation (e.g. claim-within-window or wait-and-recheck), prose decision procedure text for the agent, the topic and service slug, an ISO-8601 generation timestamp, and the generation source (llm, reasoning, or deterministic). The response also includes payment confirmation fields.
