This specific endpoint delivers premium token intelligence by combining price metrics, recent news, Twitter sentiment analysis, and futures/derivatives data for any given token symbol. It sits in the Market Intelligence category of the swarm.\n\nThe endpoint accepts a GET request with a required `symbol` query parameter (e.g., BTC, ETH, SOL) and costs $0.10 per call, payable in USDC on Base, Polygon, or Solana. Payment follows the x402 V2 protocol: an initial unauthenticated request returns a 402 with a PAYMENT-REQUIRED header containing payment options (EIP-3009 USDC, Permit2 ERC-20, or Solana USDC). After signing and resubmitting with a PAYMENT-SIGNATURE header, the caller receives a 200 response with data plus a signed EIP-712 receipt. Data endpoints like this one also support Sign-In-With-X (SIWX): after one paid call, subsequent requests within a 1-hour window can use a wallet signature for free re-access.\n\nThe response follows a standard envelope with `status` (\"success\" or \"failed\") and a `data` object containing the aggregated intelligence. The service is designed for programmatic and agent-based access, with machine-readable specs available at `/.well-known/x402` and `/llm.txt`. On-chain reputation feedback is supported via ERC-8004.","tags":[],"capabilities":["token-price-metrics","crypto-news-aggregation","twitter-sentiment-analysis","futures-data","x402-micropayment","usdc-payment","multi-chain-payment","siwx-repeat-access","eip-712-receipts","permit2-ready"],"categories":["crypto","market-intelligence","defi"],"synonyms":["token analysis","crypto alpha","token sentiment","token research","crypto intelligence","token metrics","coin analysis","token fundamentals"],"warnings":["Response data schema is untyped — the OpenAPI spec only defines `data` as a generic object without detailed properties","No concrete example response is available in the documentation; the example_response_json above is inferred","Trading-adjacent endpoint — token intelligence should not be treated as financial advice"],"endpointUrl":"https://x402.ottoai.services/token-alpha","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x0E84dDEdAaE6A779c462C22a59F301EC31B6b808","amount":"100000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300},{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2","assetTransferMethod":"permit2"},"payTo":"0x0E84dDEdAaE6A779c462C22a59F301EC31B6b808","amount":"100000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300},{"asset":"0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359","extra":{},"payTo":"0x0E84dDEdAaE6A779c462C22a59F301EC31B6b808","amount":"100000","scheme":"exact","network":"eip155:137","maxTimeoutSeconds":300},{"asset":"0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359","extra":{"assetTransferMethod":"permit2"},"payTo":"0x0E84dDEdAaE6A779c462C22a59F301EC31B6b808","amount":"100000","scheme":"exact","network":"eip155:137","maxTimeoutSeconds":300},{"asset":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v","extra":{"feePayer":"BENrLoUbndxoNMUS5JXApGMtNykLjFXXixMtpDwDR9SP"},"payTo":"6XcSfqJHr9vNW2vbiRaMqUYVm7shDgLepca54wUTDPN5","amount":"100000","scheme":"exact","network":"solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp","maxTimeoutSeconds":300}]},"qualityScore":"0.750","qualityRationale":"Full OpenAPI 3.1 schema is available with clear endpoint descriptions, parameters, and pricing.
