The endpoint is part of a broader \"crypto intelligence\" service and is gated by the x402 protocol on Base (EIP-155:8453), accepting USDC payments.\n\nEach call costs 5,000 base units of USDC (6 decimals), which equals $0.005 (half a cent). Payment is handled via Permit2 with gas sponsorship, smart-wallet support, and ERC-4337 account abstraction. The response MIME type is application/json. No OpenAPI schema or detailed documentation is available beyond the endpoint's self-description in the x402 challenge and the provider's landing page.\n\nBecause no formal docs, request/response schemas, or usage examples are published, the exact query parameters (e.g., how to specify a ticker symbol) and response shape must be discovered by making a paid call. The endpoint is confirmed live (HTTP 402 challenge returned successfully).","tags":[],"capabilities":["crypto-mentions","ticker-velocity","ticker-acceleration","lifecycle-stage-classification","x402-micropayment","base-usdc","permit2","gas-sponsored","smart-wallet","erc4337"],"categories":["crypto","data","analytics"],"synonyms":["crypto momentum","ticker mentions","social velocity","crypto buzz","mention acceleration","token lifecycle","crypto sentiment","naiko api"],"warnings":["No OpenAPI or formal documentation available; /docs, /api, /pricing, /README all return 404.","Request parameters (e.g., how to specify a ticker) are unknown — must be discovered by making a paid call.","Response schema is undocumented; the only hint is the MIME type (application/json) and the textual description in the x402 challenge.","Provider landing page is minimal; no terms of service, rate limits, or SLA information found."],"endpointUrl":"https://capable-grace-production-ab1c.up.railway.app/data/momentum","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0xB836A641DAe76424861F7f1FCb37c1295E44E329","amount":"5000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is confirmed live via a valid x402 402 challenge, and the resource description is informative.
