How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object containing the top 10 mentions (entities, keywords, or named references) found in the provided text, ranked by frequency or prominence. The exact shape of the response may vary (additionalProperties: true), but typically includes mention labels and counts or scores.
Example use cases
News article topic surfacing
“I have a long news article about the 2024 election — can you pull out the top 10 most mentioned names and topics from it so I can see who and what gets the most coverage?”
Contract entity frequency check
“Here's a legal contract I'm reviewing — can you find the top 10 most frequently mentioned terms or entities in it so I know what the document is really focused on?”
Social media post trend extraction
“I've collected a bunch of tweets into one big text blob — can you identify the top 10 most mentioned keywords or names so I can spot what's trending?”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-extract/mentions/t10?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, cheap ($0.03 USDC) ranked extraction of the top 10 mentions from a text blob without running your own NLP pipeline. It is ideal for agents that need to summarize key entities from articles, reports, or aggregated content in a single pay-per-call operation with no setup overhead. Prefer this over general LLM summarization when you want a structured, ranked list of mentions specifically.
