## 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 one-engine-text-domain-extractor-t6-86547c63 -d '<json body>'
```

Example prompt: Extract all domain names or domain-related entities from this text for me — here's the content: 'We found references to example.com, openai.com, and several other sites mentioned across the following 2,000-word article: [article text here].'

## When to prefer this

Choose this endpoint when you need a cheap, pay-per-call ($0.004 USDC) extraction of domain entities from freeform text up to 50,000 characters, especially in autonomous agent workflows that use x402 micropayments on Base. Prefer it over heavier NLP services when cost efficiency and simplicity matter and you don't need a full NLP pipeline.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- Empty or missing 'text' field — validation error
- Payment failure via x402 on Base — 402 response with payment requirements
- Ambiguous or noisy text with no extractable domains — empty or sparse result
- Cloudflare Workers timeout on very large text inputs

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

A JSON object containing extracted domain-related entities or structured data identified within the submitted text. The exact fields are flexible (additionalProperties: true), but typically include lists of detected domain names or related structured information parsed from the input.
