## 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-extract-domains-t3-ff8a8291 -d '<json body>'
```

Example prompt: Can you extract all domain names mentioned in this article text: 'Cloudflare, Google, and Amazon Web Services all expanded their infrastructure in 2024, with cloudflare.com launching new products and aws.amazon.com adding new regions'?

## When to prefer this

Choose this endpoint when you need to extract domain names or domain-like entities from unstructured text at very low cost ($0.001 USDC per call) using the x402 micropayment protocol on Base. It is well-suited for agents that process large volumes of text programmatically and need lightweight, pay-per-use domain extraction without managing subscriptions.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected or truncated
- No domains found in text — may return empty results
- Malformed or missing 'text' field — validation error
- Payment failure via x402 protocol — 402 response, no extraction performed
- Ambiguous or abbreviated hostnames may be missed or misidentified

## How this service works

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

## Output

Returns a JSON object containing extracted domain names and/or domain-related entities found within the submitted text. The exact output structure is flexible (additionalProperties: true), but expected to include identified domains or structured data derived from parsing the input text.
