Developers

Make your agent fluent in crypto

106 API operations and 100+ query-ready onchain tables spanning prediction markets, market data, onchain SQL, wallets, and news — through a REST API, agent skill, CLI, or MCP server. The routing, schemas, and entity resolution come pre-built.

Every crypto discipline, without the quality tax

A DIY harness degrades as it grows: more tools, noisier routing, worse answers. The Surf skill is designed so each domain you add — onchain SQL, wallet intelligence, prediction markets, funding data — only adds. One install, and your agent keeps what it was already good at.

✓One-line install into Claude Code, Cursor, OpenClaw
✓100+ commands across 13 data domains
✓Entity resolution and schemas handled below the prompt
✓Onchain SQL against an analyst-ready ClickHouse warehouse
✓Cross-market prediction data (23 commands) no other provider carries

What you can build

From copilots to data feeds

Every workflow below runs on the same endpoints you get on day one.

01
Trading copilot
A chat agent that answers with cited market context — live prices, funding, and positioning pulled inline.
market-data · prices
02
Prediction-market analytics dashboard
Track volume, open positions, and resolution odds across venues. We built ours on the same API.
See the dashboard we built→
prediction-market
03
Agent skills with onchain evidence
Give any agent answers backed by onchain SQL and 100M+ labeled addresses instead of a general model’s guess.
onchain-sql · wallets
04
A market-data feed for your app
Stream prices, tokens, and DEX trades straight into your product through typed REST endpoints.

Developer tools

Four ways in, one data surface

Data API

Typed REST endpoints, plus direct onchain SQL over Surf’s ClickHouse warehouse.

GET api.asksurf.ai/gateway/v1/...

Agent Skill

One install gives any coding agent the full data surface, citations included.

npx skills add asksurf-ai/surf-skills --skill surf

CLI

Every data domain from your terminal, scriptable by design.

docs.asksurf.ai/cli/introduction

MCP Server

The full command set as native tools in any MCP-compatible client.

docs.asksurf.ai/cli/mcp

How it works

Three steps to your first call

01
Get an API key
Sign up on the developer platform and generate a key.
02
Install the skill or call the API
Add the agent skill in one line, or hit the REST endpoints.
03
Ship
Wire the responses into your agent, app, or dashboard.

Cross-market matching, only on Surf

Polymarket and Kalshi in one place: events, odds, orderbooks, trades, positions. Cross-market matching shows when the two venues disagree about the same event — the spread no single-venue tool can see.

·Polymarket + Kalshi dual coverage (20+ endpoints)
·Cross-market matching: find equivalent markets across platforms
·Orderbook snapshots with bid/ask depth
·Address profiler: whale positions and trading history
·Category classification: politics, economics, tech, sports, crypto
·30 ClickHouse tables (934M+ rows of trade data)

Analyst-ready SQL, sub-second answers

Direct SQL over 80+ ClickHouse tables: DEX trades, transfers, prices, TVL, lending, staking, and bridges. Your agent inspects the schema itself and writes its own queries — no dashboard in between.

·80+ ClickHouse tables across 11 data categories
·DEX trades (7 chains): Uniswap, Curve, PancakeSwap, Sushiswap, Aerodrome, Balancer…
·Token transfers, prices (daily + VWAP), TVL, fees, yields
·Lending flows (Aave, Compound, Morpho), staking (Lido, Rocket Pool)
·Prediction market tables (30 tables, 934M+ trade rows)
·Schema inspection: agent auto-discovers table structure
·Live chains: Ethereum, Arbitrum, Base, BSC, Tempo, TRON, HyperEVM

Every wallet, fully profiled

Balances, DeFi positions, transaction history, and labels across every supported chain in one query — whether you are tracking a whale or explaining a portfolio to its owner.

·DeFi position breakdown: Aave, Lido, Uniswap, Compound, Curve, Morpho
·Historical transaction log with token-level detail
·Wallet label system: Whale, Smart Money, Exchange, Bridge, Bot
·Batch label lookups for address enrichment
·6 wallet endpoints

100M+ addresses with names attached

Surf labels 100M+ wallets across 13 networks — exchanges, funds, whales, bridges, MEV bots, named specifically — so onchain evidence arrives with the actors already identified.

·100M+ labeled addresses across all major networks
·13 chains: all EVM networks, Solana, TRON, Bitcoin, TON

·Categories: CEX, DEX, Whale, Fund, Bridge, Protocol, MEV, Miner, Contract
·Batch label lookups for address enrichment pipelines
·6 wallet endpoints with full label + balance + DeFi position data

Funding rounds as queryable data

Round-by-round funding history with investors and valuations, VC portfolio composition, and fund rankings — structured fields your agent can filter and join, not web scrapes.

·Complete funding round history: seed, Series A/B/C, amount, date, valuation
·Investor lists per round: lead investors, co-investors

Every API on the left is another adapter, another schema, another thing that breaks. Surf keeps the coverage and takes over the layer in between — so your agent reads one surface.

One Surf Layer

One API Key

106 API Operations

One key. One install. One layer.

Not another data vendor: Anyone can sell you endpoints. Surf sells the layer that makes an agent reliable across all of them at once: routing, normalization, entity resolution.
Additions never subtract: In a hand-built harness, every new domain makes tool selection noisier. Surf is designed so new disciplines leave the answers your agent already gives untouched.
Start without a procurement cycle: Full-stack coverage normally means separate vendors and annual contracts. Surf is one key, pay-as-you-go — priced to try this afternoon.
