It is part of the Naiko pay-per-call crypto intelligence platform, which uses the x402 protocol for micropayments.\n\nEach call costs $0.01 (10,000 base units of USDC on Base, network eip155:8453). Payment is handled via the x402 protocol version 2 using Permit2 asset transfers. Gas is sponsored, smart wallets are supported, and ERC-4337 deployment is available, making the payment flow accessible to both EOA and smart-contract wallets.\n\nDocumentation is sparse — the provider's /docs, /api, /pricing, and /README paths all return 404. The endpoint description and response MIME type (application/json) are sourced from the x402 challenge itself. The exact schema of the returned JSON (narrative fields, momentum metrics, ticker structure) is not documented and must be discovered by making a paid call.","tags":[],"capabilities":["crypto-narratives","trending-tickers","momentum-indicators","x402-micropayments","base-usdc","permit2-transfer","gas-sponsored","smart-wallet-supported","erc4337"],"categories":["crypto","market-data"],"synonyms":["crypto narratives","trending narratives","narrative momentum","crypto market themes","sector rotation crypto","crypto thematic analysis","narrative trading","token narratives"],"warnings":["No API documentation available — /docs, /api, /pricing, /README all return 404","Response schema is unknown; field names and structure must be discovered via a paid call","No OpenAPI or ai-plugin manifest found","No agents.txt present"],"endpointUrl":"https://capable-grace-production-ab1c.up.railway.app/data/narratives","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0xB836A641DAe76424861F7f1FCb37c1295E44E329","amount":"10000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The endpoint is live and returns a valid x402 challenge with a clear description and pricing.
