Implementation Reference
- index.js:738-739 (handler)The handler case for 'search_tokens_semantic' tool call, which proxies the arguments to the ChainFetch API semantic search endpoint for tokens.
case 'search_tokens_semantic': return await this.makeRequest('/api/v1/ethereum/tokens/semantic_search', 'GET', args, null, token); - index.js:383-400 (schema)Input schema and metadata definition for the 'search_tokens_semantic' tool, provided in the listTools response.
