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-release-gate-quick-answer-43e71bb1 -d '<json body>'
```

Example prompt: Given this context — 'Our refund policy allows returns within 30 days of purchase with a receipt' — can you quickly answer: 'Does the policy cover items bought without a receipt?'

## When to prefer this

Choose this endpoint when you need a cheap ($0.001), fast, single-shot answer to a question grounded in a provided context — especially in agentic pipelines where you want to avoid signing up for an API key. Ideal for task routing, fact extraction, or quick quality checks on generated content. Prefer it over heavier LLM endpoints when the question is simple, context fits within 6000 chars, and cost-per-call matters.

## Known failure modes

- Question or context exceeds character limits (question >4000 chars or context >6000 chars) — request rejected
- Payment failure over x402/MPP — 402 response returned before processing
- Ambiguous or unanswerable question relative to context — Claude may return a best-effort or hedged answer
- Empty question field — schema validation error
- Upstream Claude API unavailability — 5xx error from the service

## How this service works

Agent Release Gate: an independent quality check that tells an AI agent whether its output is ready to ship, with repair instructions when it is not. Also offers low-cost utilities for quick answers, summaries, task routing, structured JSON extraction, and Claude text generation. Pay per call with USDC over x402 on Base or MPP on Tempo; no API key or signup.

## Output

A short natural-language answer generated by Claude based on the provided context and question. Returned as text, directly addressing the question without additional scaffolding.
