# Agent Rest Stop – Retry/Pay/Abort Decision Engine

> Agent Rest Stop – Retry/Pay/Abort Decision Engine is a paid API for AI agents from agent-gas-station.agent-gas-station.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-31).

Given an error status from an API call, decides whether the agent should retry the request, pay to proceed, or abort the operation entirely.

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 agent-rest-stop-retry-pay-abort-decision-engine-e384d597 -d '<json body>'
```

Example prompt: I just got back a '402 Payment Required' status with the error 'insufficient credits' — should I retry, pay, or abort?

## When to prefer this

Use this endpoint when an AI agent needs to make an automated, deterministic recovery decision after a failed API call — especially in x402-payment-aware workflows where 'pay to proceed' is a valid option alongside retry and abort. Prefer this over hardcoded if/else logic when the set of statuses and errors is diverse or when you want a centralized, auditable decision point for all agent error-handling.

## Known failure modes

- Missing or empty 'status' field may result in indeterminate or default response
- Ambiguous error strings may lead to a conservative 'abort' recommendation
- Unrecognized status codes may not map cleanly to a retry/pay/abort decision
- Network timeout to the worker endpoint itself requires caller-side fallback logic

## How this service works

Chooses retry, pay, or abort from a status.

## Output

A structured decision indicating which of three actions the agent should take — retry the request, initiate payment to proceed, or abort the operation — based on the provided error and status inputs.
