Use when the user wants crypto data — token prices, on-chain SQL, prediction-market positions, CEX order books, wallet labels/net-worth, social mindshare, news, or unified search. 83 endpoints across exchange, on-chain, wallet, social, prediction, news and search — one API, flat $0.0095/call in USDC via x402. Settles directly to Surf's Base treasury; no Surf account needed.

One of 18 test cases the skill fixed. Same model, same prompt, with and without the skill.

The instructions your model reads when the skill loads.
Surf (asksurf.ai) is no longer served through BlockRun. Since 2026-09-06 the
gateway answers every /v1/surf/* path with:
HTTP 410
{"error":{"code":"endpoint_retired","message":"The Surf data endpoints are retired. We are looking for a new vendor in this space and expect to publish a replacement under /api/v1/."},
"retired_on":"2026-09-06",
"alternatives":[{"for":"crypto, equity, FX and commodity prices","endpoint":"/api/v1/crypto/price"},
{"for":"protocol TVL and yields","endpoint":"/api/v1/defillama/*"},
{"for":"prediction markets","endpoint":"/api/v1/pm/*"},
{"for":"DEX quotes and swaps","endpoint":"/api/v1/zerox/*"}]}
Verified live 2026-09-08 with an unauthenticated GET (a 410 is free to fetch).
sol.blockrun.ai answers 404 on the same paths, and /api/openapi no longer
lists any Surf route. No 402 is ever issued, so no payment can be made.
blockrun_surf was removed from the server in 0.49.0 and is no longer one of
the 19 tools: a tool that can only
return an error is not worth the schema every agent carries on every turn. An
MCP client will answer an unknown-tool error if a config still names it. Nothing
can be charged either way. Do not describe this as a temporary outage — it is
not; route the question with the table below.
