Pay-per-call trending crypto narrative categories with momentum indicators and top tickers.
What it does
Naiko x402 API provides a pay-per-call endpoint that returns trending narrative categories in the crypto market, including momentum indicators and the top tickers associated with each narrative. The endpoint is accessed via the x402 protocol on Base (EIP-155:8453), settling payments in USDC.
Each call costs $0.01 (10,000 base units of USDC with 6 decimals) and supports gas-sponsored transactions, smart wallet compatibility, and ERC-4337 account abstraction. The transfer method is Permit2. The endpoint returns JSON data and is live, responding with a standard x402 payment challenge to unauthenticated requests.
Documentation is minimal — the provider's landing page confirms it is a "pay-per-call crypto intelligence" service, but dedicated docs, OpenAPI specs, and detailed endpoint descriptions are not available. The resource description embedded in the x402 challenge is the primary source of information about what the endpoint returns.

Quality
The x402 challenge is live and well-formed, providing clear pricing and resource description. However, there is no OpenAPI spec, no dedicated documentation, no example responses, and no additional endpoint details beyond the challenge metadata. Most capability claims are inferred from the single resource description field.
Warnings
- —No OpenAPI or dedicated API documentation available — /docs, /api, /pricing, /README all return 404
- —Response schema and field definitions are unknown; no example responses available
- —Capabilities inferred solely from the x402 challenge resource description
