## 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-summarize-735646d6 -d '<json body>'
```

Example prompt: Summarize this meeting transcript in bullet-point style, keeping it under 200 tokens: [paste transcript here].

## When to prefer this

Choose this endpoint when you need a fast, cheap per-call text summarization with style control (bullets, brief, decisions, risks) and no API key or subscription. Ideal for agents that need to digest documents on demand and pay only for what they use via USDC on Base. Prefer over general LLM calls when cost predictability and micropayment settlement matter.

## Known failure modes

- Text too short (minLength 1 not met) — validation error
- Text exceeds 12,000 character limit — request rejected
- Invalid style enum value — defaults or errors depending on server
- maxTokens out of range (below 32 or above 256) — validation error
- Payment not received or insufficient USDC — 402 Payment Required
- Service temporarily unavailable on Railway — 503 or timeout

## 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 concise summary of the submitted text in the requested style (bullets, brief, decisions, or risks), bounded by the maxTokens parameter. The response is plain text generated by Claude, typically a few sentences or a short bulleted list.
