AI-analyzed overnight crypto token movers via pay-per-call x402 protocol
What it does
Naiko's `/alpha/overnight` endpoint returns tokens that moved significantly during off-hours (midnight to 8 AM UTC) along with AI-generated analysis explaining what happened while you slept. It is a pay-per-call API using the x402 protocol, settling payments in USDC on Base (EIP-155 chain 8453).
Each call costs $0.01 (10,000 base units of USDC with 6 decimals). The endpoint supports gas-sponsored transactions, smart wallet compatibility, ERC-4337 account abstraction, and uses the Permit2 asset transfer method. The response is served as `application/json`.
Documentation beyond the x402 challenge and the landing page is sparse — there is no OpenAPI spec, no dedicated docs page, and no detailed schema for the response payload. The endpoint is live and returns a well-formed x402 version 2 challenge on unauthenticated GET requests. Additional endpoints may be discoverable via the `/health/endpoints` and `/.well-known/x402` discovery paths listed on the landing page.

Quality
The endpoint is live and returns a well-formed x402 v2 challenge with clear pricing and a useful resource description. However, there is no OpenAPI spec, no response schema, no example responses, and no documentation pages — all return 404. Most details are inferred from the challenge payload alone.
Warnings
- —No OpenAPI or response schema available — response structure is unknown
- —No documentation pages found (/docs, /api, /pricing, /README all return 404)
- —Response payload fields and structure must be discovered empirically
