Install

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

Works with any agent that supports the skills protocol — Claude Code, Codex, and more.

Prerequisites

Install the Surf CLI following the guide at agents.asksurf.ai/docs/cli/introduction

No API key required to start — you get 30 free credits daily. For full access, sign up at agents.asksurf.ai and run:

bashCopy
surf auth --api-key $API_KEY

What It Does

Once installed, your agent can fetch live crypto data just by you asking for it — no endpoints to memorize.

Example prompts your agent will handle:

• "What's the price of ETH?"
• "Show me the top 10 wallets holding AAVE"
• "Get Polymarket odds for the next US election"
• "Find trending crypto projects on Twitter"
• "What's the TVL of Uniswap on Arbitrum?"
• "Show me BTC funding rates across exchanges"

The skill teaches the agent to discover endpoints, use correct parameters, and return structured data — automatically.

Data Coverage

Wallet	Balances, transfers, DeFi positions, net worth, wallet labels
Social	Twitter/X profiles, posts, followers, mindshare, sentiment, smart followers
Token	Holders, DEX trades, transfers, unlock schedules, tokenomics
Project	Profiles, DeFi TVL, protocol metrics, DeFi rankings
Prediction Markets	Polymarket & Kalshi — markets, trades, prices, volume, open interest, rankings
On-chain	Transaction lookup, SQL queries, gas prices, bridge rankings, yield rankings
News & Search	Cross-domain entity search, news feed, web fetch
Fund	VC fund profiles, portfolios, rankings

CLI Quick Reference

The skill uses the surf CLI under the hood. You can also use it directly:

bashCopy
# Discovery
surf sync                                    # Refresh API spec cache
surf list-operations                         # All available commands
surf list-operations | grep market           # Filter by domain
surf market-price --help                     # Full params and enums

# Fetch data
surf market-price --symbol BTC -o json -f body.data
surf wallet-detail --address 0x... -o json -f body.data
surf social-user --handle vitalikbuterin -o json -f body.data

# On-chain SQL
echo '{"sql":"SELECT project, sum(amount_usd) FROM agent.ethereum_dex_trades WHERE block_date = today() - 1 GROUP BY project ORDER BY 2 DESC LIMIT 10"}' | surf onchain-sql

How It Works

The skill (skills/surf/SKILL.md) is an instruction file that teaches your AI agent to:

1. Run surf sync to refresh the API spec cache
2. Use surf list-operations and surf <command> --help to discover the right endpoint
3. Use -o json -f body.data for structured output
4. Map natural language requests to the correct domain and parameters
5. Handle pagination, chain name conventions, and common gotchas

No code generation needed — the agent calls the CLI directly and returns the data.

Adding New Endpoints

No changes needed in this repo. When a new API endpoint is added upstream:

1. The OpenAPI spec updates automatically
2. surf list-operations shows the new command
3. surf <new-command> --help shows its parameters
