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 and structured information derived from the input text. The exact schema is flexible (additionalProperties: true), so the response may include lists of identified domains, entity metadata, or other structured extraction results depending on the text content.
Example use cases
Domain audit from contract text
“I have this legal contract text that mentions a bunch of third-party vendors and websites — can you pull out all the domain names and web entities mentioned in it so I can audit our third-party dependencies?”
Extract domains from scraped article
“I just scraped this 10,000-word news article about the tech industry. Can you extract all the domain names and website references mentioned in the text so I can build a list of sources?”
Parse domains from email dump
“Here's a big batch of raw email content from our sales team. Extract every domain or website reference you can find from this text so we can see which companies they've been in contact with.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-extract/domains/t7?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to extract domain-related entities from unstructured text at very low cost ($0.0065 USDC per call) using x402 micropayments on Base. It is well-suited for autonomous agents processing documents, articles, emails, or data dumps where identifying web domains or domain entities is the primary goal. Prefer this over general-purpose LLM extraction when you want a pay-per-call, deterministic, low-overhead API without managing API keys.
Side effects
- Text exceeds 50,000 character limit — request rejected or truncated
- Empty or missing 'text' field — validation error returned
- Payment failure via x402 on Base — 402 response if USDC payment not authorized
- Ambiguous or low-signal text may return sparse or empty extraction results
- Network timeout on Cloudflare Workers edge — transient 5xx error
