Surf — retired on BlockRun (2026-09-06)

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.

Where each former Surf capability lives now

The user wants…	Surf used to be	Use now	Cost
BTC/ETH/any coin price, OHLC history	market/price, exchange/klines	blockrun_price action:"price" / "history" category:"crypto"	FREE
FX, gold, oil	market/price	blockrun_price category:"fx" / "commodity"	FREE
Fear & Greed, market ranking by cap	market/fear-greed, market/ranking	blockrun_price action:"list" for the symbol universe; no sentiment index on BlockRun	FREE / none
DEX pair, liquidity, volume, token by contract	token/dex-trades, search/project	blockrun_dex	FREE
Token price by contract address	market/price	blockrun_defi path:"prices/{coins}"	$0.001 + fee
Protocol / chain TVL, yield rankings	project/defi/ranking, onchain/yield/ranking	blockrun_defi path:"protocols" / "chains" / "yields"	$0.005 + fee
Polymarket / Kalshi markets, prices, positions	prediction-market/*, search/polymarket, search/kalshi	blockrun_markets — see skills/prediction-markets/SKILL.md	$0.0075 + fee
Who is this Polymarket wallet, and which wallets are theirs	wallet/detail, wallet/labels/batch (for Polymarket traders only)	blockrun_markets polymarket/wallet/identity/{wallet} + polymarket/wallet/{address}/cluster	$0.0075 + fee
Gas price, a transaction, a balance, a contract read	onchain/gas-price, onchain/tx	blockrun_rpc (eth_gasPrice, eth_getTransactionByHash, eth_getBalance, eth_call) — see skills/rpc/SKILL.md	$0.002 + fee
Web / news search	search/web, search/news, news/feed	blockrun_exa (neural) or blockrun_search (Grok Live Search, web + X + news)	$0.01 + fee / $0.025 × results

"fee" is the gateway's flat network fee — $0.001 per call on Base today; the Solana gateway quotes the base alone; the account rail charges no fee.

What has NO replacement on BlockRun yet

Say so plainly rather than substituting something that answers a different question:

• Raw on-chain SQL over ClickHouse (onchain/sql, onchain/query, onchain/schema)
• Wallet labels and net worth across 13 chains for arbitrary addresses (wallet/labels/batch, wallet/net-worth, wallet/protocols, wallet/history). Only Polymarket traders are covered, via blockrun_markets identity/cluster above.
• CEX order books, perp snapshots, funding history, long/short ratio, options skew (exchange/*, market/options, market/futures)
• ETF flows, liquidation charts, on-chain indicators (market/etf, market/liquidation/*, market/onchain-indicator)
• Social / CT intelligence — mindshare, smart followers, KOL search, tweet search (social/*, search/social/*)
• Tokenomics and unlock schedules, token holders and transfers (token/*)
• VC fund portfolios and rankings (fund/*)
• Bridge rankings, airdrop search, project profiles (onchain/bridge/ranking, search/airdrop, project/detail)
• Webpage-to-markdown (web/fetch)

The gateway says a new vendor is pending and that the replacement will be published under /api/v1/ and listed at https://blockrun.ai/api/openapi. Check there before promising any of the above.

Worked example — what a former Surf request looks like now

"Is this whale wallet labeled, and what does it hold?" (was 4 Surf calls, $0.034)

// If it is a Polymarket trader — identity, linked wallets, P&L:
blockrun_markets({ path: "polymarket/wallet/identity/0xWHALE" })
blockrun_markets({ path: "polymarket/wallet/0xWHALE/cluster" })
blockrun_markets({ path: "polymarket/wallet/pnl/0xWHALE" })

// For any address — current native + token balances via raw RPC (free tools first):
blockrun_rpc({ network: "ethereum", method: "eth_getBalance", params: ["0xWHALE", "latest"] })

Cross-chain labels (CEX / MEV / bridge) and a net-worth time series are not available on BlockRun right now — tell the user that. blockrun_surf no longer exists.
