## 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 polyform-text-summarize-43aaba5a -d '<json body>'
```

Example prompt: Can you summarize this article for me: 'Central banks around the world are raising interest rates to combat persistent inflation, but economists warn the moves could tip several economies into recession by early next year...' — just give me the key points in a short paragraph.

## When to prefer this

Choose this endpoint when you need frictionless, one-shot text summarization with no API key or account setup — ideal for AI agents that want to pay per use with USDC on Base via the x402 protocol. Best when you need Llama-quality summaries without committing to a subscription or managing credentials.

## Known failure modes

- Missing or malformed 'input' body returns a validation error
- Payment not included or insufficient USDC causes a 402 Payment Required response
- Body type mismatch (e.g. sending form-data when json is expected) may cause parsing failure
- Very short or empty text input may produce a trivial or empty summary
- Network timeouts on large text inputs if the model takes too long

## How this service works

Pay-per-call data endpoints for AI agents. USDC on Base via x402. No account, no API key — one micropayment per call.

## Output

A JSON object containing the model identifier (e.g. 'llama-3.3-70b') and a 'summary' string — a concise, LLM-generated condensation of the submitted text.
