## 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-b0ed3b08 -d '<json body>'
```

Example prompt: Extract all the named entities — people, organizations, locations, and dates — from this paragraph: 'On March 5, Elon Musk met with Apple executives in Cupertino to discuss a potential partnership.'

## When to prefer this

Choose this endpoint when you need machine-payable, per-call named entity recognition without managing an NLP infrastructure subscription. It is well-suited for AI agents that need to extract entities on-demand from dynamic text inputs and can autonomously handle USDC micropayments via x402 on Base mainnet. Prefer this over larger NLP platform APIs when cost-per-call pricing is preferable to subscription tiers and when the agent stack already supports x402 payment headers.

## Known failure modes

- Empty or missing text field returns an error or empty entity list
- Text too long may be truncated or rejected depending on service limits
- Ambiguous entities may be misclassified (e.g. Apple as fruit vs. company)
- Payment failure on Base mainnet causes 402 response and no result
- Tunnelmole tunnel URL may be ephemeral and go offline without notice
- Malformed JSON input returns a 400 error

## 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

Returns a structured list of named entities found in the input text, each typically annotated with the entity type (e.g. PERSON, ORG, GPE, DATE) and the span or text value of the entity. Payment of $0.004 USDC is deducted per successful call via x402 on Base mainnet.
