How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A structured object containing identified token or keyword mentions found within the submitted text, including their positions or counts depending on the implementation.
Example use cases
Crypto news article token scanner
“I have this crypto news article — can you pull out every token or coin that gets mentioned in it? Here's the text: 'The DeFi sector exploded this week as ETH, AAVE, UNI, and a new token called MOODENG all hit multi-month highs amid broader market optimism.'”
Social media post token mention audit
“Go through this batch of social media posts and tell me every token name or symbol that appears: 'Just bought more SOL and ADA, also eyeing some ARB and OP for the next bull run. Anyone else holding LINK?'”
Whitepaper token reference extraction
“Extract all the token mentions from this whitepaper introduction so I can see what assets the project references: 'Our protocol integrates with USDC, ETH, and BTC as collateral, while issuing our native governance token XYZ for voting rights.'”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-token/mentions/t2?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to extract token or keyword mentions from a large block of text (up to 50,000 characters) in a pay-per-call model without subscription overhead. It is particularly well-suited for crypto/DeFi agent workflows that process news, social media, or research documents and need to identify which tokens are referenced. Prefer it over full NLP pipelines when you only need mention detection at very low cost ($0.0007 per call).
Side effects
- Text exceeds 50,000 character limit — request rejected or truncated
- Empty text field — API returns error or empty mention list
- No token mentions found in text — returns empty mentions array
- Payment failure via x402 — 402 response returned before processing
- Malformed request body — 400 error if required 'text' field is missing
