## 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 x402-agent-economy-lab-text-summarization-api-77cd0924 -d '<json body>'
```

Example prompt: Can you summarize this article for me? Here's the text: 'Central banks across Europe raised interest rates by half a percentage point today amid concerns about persistent inflation, marking the third consecutive hike this quarter and sending markets lower across the board.'

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call text summarization service with no subscription overhead, especially in agentic pipelines that already support x402 USDC micropayments on Base mainnet. It is well-suited for agents that need to summarize arbitrary text on demand without setting up a full LLM integration, and when per-call cost predictability ($0.008 USDC) matters.

## Known failure modes

- Empty or missing 'text' field returns a 400 bad request error
- Text too long may be truncated or rejected depending on server-side limits
- Payment failure (insufficient USDC balance or x402 handshake error) results in a 402 Payment Required response
- Tunnelmole tunnel may be offline or unreachable, resulting in connection timeout
- NLP backend overloaded may return 503 or slow response

## How this service works

Machine-payable NLP micro-services: sentiment, entity extraction, summarization, report, batch. Paid per call in REAL USDC on Base mainnet.

## Output

A concise summary of the input text, returned as a text response. The length and style of the summary depend on the service's NLP model, typically reducing a long passage to its key points in a few sentences.
