ByKaranteli X402 API

Per-call priced history and depth endpoints, settled in USDC over the x402 protocol on Solana and Base mainnet through the Coinbase CDP facilitator. 13 priced endpoints plus the free catalog at /api/x402, which is the authoritative price list. Verified 2026-08-11: the catalog lists 13 endpoints from $0.002 to $0.010, and a priced endpoint returns HTTP 402. These sell depth and history, never access.
