## 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-entity-extraction-api-e888b307 -d '<json body>'
```

Example prompt: Can you extract all the named entities — people, organizations, locations, and dates — from this text: 'Apple CEO Tim Cook announced a new partnership with Samsung in Seoul last Tuesday.'

## When to prefer this

Choose this endpoint when you need a cheap, pay-per-call ($0.004 USDC) entity extraction microservice that integrates natively with x402 autonomous payment rails on Base mainnet — ideal for AI agents that handle their own micropayments without a subscription or API key setup. Prefer it for lightweight, one-off entity extraction tasks in agentic pipelines.

## Known failure modes

- Empty or missing 'text' field returns a 400 error
- Text too long may exceed processing limits and return a 413 or truncated result
- Payment failure on Base mainnet (insufficient USDC, bad wallet) returns 402
- Tunnelmole tunnel may be offline or unreachable, returning 503 or connection timeout
- Ambiguous text may yield low-confidence or missed entities with no explicit confidence score returned
