How this service works
Pay-per-call tools for people building AI agents: live web search and page contents, point-in-time crypto market data and news for backtests (no lookahead), verifiable track records of 1,000 crypto strategies locked on the Base network, company profiles, quick AI and batch prices. Ask us to turn a public website into a JSON endpoint. Pay per call, no account, free trial.
Output
A JSON object with a 'topic' field (a short string describing the overall subject) and a 'keywords' array of extracted key terms ranked by relevance, limited to the requested maximum count.
Example use cases
Tag AI news articles automatically
“Pull the top 8 keywords and main topic from this article text so I can auto-tag it in my CMS: 'Decentralized finance platforms are integrating AI agents to automate yield optimization across multiple protocols.'”
Summarize trading strategy description
“Give me the core topic and up to 5 keywords from this strategy description: 'This mean-reversion strategy buys Bitcoin when RSI drops below 30 and sells when it recovers above 50, targeting short-term oversold bounces.'”
Content SEO keyword extraction
“Extract the main topic and the top 10 keywords from this blog post draft so I can use them for SEO meta tags — here's the text: 'On-chain analytics tools are becoming essential for retail investors trying to track whale movements and predict price action in crypto markets.'”
