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 entities or structured domain-related information found within the submitted text. The exact schema is open-ended (additionalProperties: true), so the response may include arrays of domain strings, metadata about each domain, or other domain-related fields depending on the service implementation.
Example use cases
Domain audit from marketing copy
“I have this big block of marketing copy and I need to know every external domain or website it references — can you pull out all the domain names from it?”
Competitive intelligence from analyst report
“Here's a 40,000-character analyst report on the AI industry. Can you extract all the company domains or website addresses mentioned throughout it so I can build a competitor list?”
Link extraction from scraped email thread
“I scraped an email thread and it's full of references to different websites and services. Can you go through this text and pull out every domain name that appears in it?”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-extract/domains/t2?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a low-cost, pay-per-call extraction of domain entities from text as part of an autonomous agent workflow on Base/x402. At $0.0007 USDC per call it is extremely cheap for high-volume pipelines. Prefer it over general-purpose LLM extraction when you want a deterministic, structured API response rather than a language model's free-form output.
Side effects
- Text exceeding 50,000 characters may be rejected or truncated
- Empty or whitespace-only text may return empty results
- No domains present in text returns an empty or null result set
- Payment failure via x402 protocol prevents the call from completing
- Malformed JSON request body returns a 400 error
- Rate limiting or quota exhaustion may return 429 errors
