How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object containing the extracted entity mentions found in the input text, including spans, labels, or metadata about each mention (exact schema is open/additionalProperties:true, so fields may vary but typically include mention text, type, and position).
Example use cases
News article entity tagging
“Pull out every person, company, and location mentioned in this news story so I can tag them in our content system: 'Elon Musk's Tesla announced a new Gigafactory in Mexico this week, drawing praise from Governor Samuel García.'”
Contract party identification
“Scan this contract excerpt and list every party, organization, or named entity mentioned in it: 'This agreement is between Acme Corp, headquartered in Delaware, and BrightPath LLC, represented by CEO Jane Harlow.'”
Social media mention extraction
“Find all the brand and person mentions in this batch of social media posts so I can route them to the right teams: 'Just had the best experience at Starbucks! @BarackObama tweeted about Nike's new campaign too.'”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-extract/mentions/t1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap, low-latency, pay-per-call mention extraction from raw text without managing a full NLP pipeline or subscription. At $0.0005 USDC per call it is cost-effective for high-volume agent workflows. Prefer it over heavier NER APIs when you have text already in hand (not a URL to scrape) and need entity mentions quickly with no setup overhead.
Side effects
- Text exceeds 50,000 character limit — request rejected or truncated
- Empty or whitespace-only text input — may return empty mentions array
- Malformed JSON body — 400 error
- Payment failure via x402 on Base — 402 response if wallet balance insufficient
- Ambiguous or low-quality text may result in missed or spurious mentions
- Service unavailability on Cloudflare Workers edge — 503 or timeout
