How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object containing the domains or URLs extracted from the provided text, returned as structured data with no fixed schema (additionalProperties: true), so the agent should expect a flexible response object listing detected domain entities.
Example use cases
Domain audit from marketing copy
“Pull out every domain name mentioned in this product announcement draft so I can check whether any competitor sites are accidentally referenced.”
Link extraction from scraped articles
“I have 10,000 characters of scraped news article text — can you find and list all the website domains mentioned in it?”
Log file domain identification
“Here's a chunk of server log output — extract every domain name that appears so I can check them against our allowlist.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-extract/domains/t4?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap, fast, pay-per-call extraction of domain names or URLs from a block of text without setting up a heavier NLP pipeline. It is especially suitable for autonomous agents that process variable text volumes and want microtransaction-based pricing via x402 on Base, rather than subscription APIs. Prefer it over regex-only solutions when you want a managed, API-backed extraction service.
Side effects
- Text exceeding 50,000 characters may be rejected or truncated
- No domains present in the text results in an empty or null domain list
- Malformed or ambiguous text may produce incomplete extraction
- Payment failure via x402/Base may result in 402 response before processing
- Rate limiting or worker availability issues may cause transient 5xx errors
