Surf — Unified Crypto Data API (via ClawRouter)

Surf bundles 83 endpoints across 12 domains into one paid HTTP API. ClawRouter exposes them at http://127.0.0.1:8402/v1/surf/*, paid the same way ClawRouter pays for LLM calls — an x402 USDC micropayment from the local wallet, or a draw on BlockRun account credit if an API key is configured (verified working on both, 2026-09-05). No Surf account and no Surf API key either way. Upstream lives at api.asksurf.ai/gateway/v1 — ClawRouter forwards transparently.

Pricing — flat per call, the same for every endpoint.

Surf used to be tiered at $0.001 / $0.005 / $0.020. It is not any more: upstream now prices all three tiers identically (SURF_TIER_{1,2,3}_PRICE are equal). The Tier column in the catalog below still describes endpoint weight, but it no longer affects what you pay. Anything quoting the old tier prices is stale.
