## 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-analysis-api-6d1559f2 -d '<json body>'
```

Example prompt: Analyze the sentiment of this product review and extract any named entities from it: 'The battery life on the XPhone Pro is incredible, but customer support from TechCorp was frustrating and slow.' — pay the $0.02 USDC per-call fee automatically.

## When to prefer this

Choose this endpoint when your agent needs to perform NLP tasks (sentiment, entity extraction, summarization) on arbitrary text and can autonomously pay micro-fees in USDC via the x402 protocol on Base mainnet. It is well-suited for agentic pipelines that need per-call, pay-as-you-go NLP without subscription management. Prefer this over free or subscription NLP APIs when operating in a machine-to-machine economy context or testing x402 payment rails with real USDC.

## Known failure modes

- Payment failure or insufficient USDC balance causes 402 Payment Required response
- Empty or missing 'text' field returns a 400 Bad Request error
- Extremely long text inputs may exceed processing limits and return a 413 or timeout
- Network tunnel instability on tunnelmole host may cause intermittent 503 errors
- Unsupported task type returns an error or unexpected output
- Rate limiting may apply if too many calls are made in rapid succession
