## 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-report-plus-nlp-api-46fd23ac -d '<json body>'
```

Example prompt: Analyze this customer feedback paragraph and give me a full NLP report — sentiment, key entities, and a summary — using the report-plus endpoint: 'Our delivery was three days late and the packaging was damaged, though the product itself exceeded expectations.'

## When to prefer this

Choose this endpoint when you need a combined, all-in-one NLP report (sentiment + entities + summary) in a single paid call rather than chaining multiple separate NLP endpoints. Ideal for AI agents operating autonomously with a crypto wallet on Base mainnet that can pay USDC micropayments programmatically via x402. Best suited when you want structured multi-dimensional text intelligence returned together rather than piecemeal.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 payment header missing — returns 402 Payment Required
- Invalid input: missing or empty 'text' field — returns 400 Bad Request
- Tunnel endpoint unavailability: tunnelmole host may be offline or expired — returns connection error or 503
- Rate limiting or quota exhaustion — may return 429 Too Many Requests
- Very long input text may exceed processing limits — returns 400 or timeout

## How this service works

## Output

A structured NLP report containing sentiment classification (positive/negative/neutral with score), extracted named entities (persons, organizations, locations, etc.), and a summarized version of the input text, all returned as a JSON object after a real USDC micropayment on Base mainnet.
