Surf Skill: The Crypto Data API for AI Agents

Crypto fluency has long eluded vibe coding. Turns out all it takes to make your agent stack crypto fluent is one command line prompt.

Today we released a Skill that gives your agent real-time prices from 16 exchanges, onchain SQL across seven chains, social intelligence, cross-platform prediction market data, a news feed, and more. Twelve data domains. 83 commands.

All it takes is a couple minutes. Your agent reads the Skill, learns the commands, and starts using the data that was missing. No afternoon lost to API docs. No five different skills covering what can be done by one. No sketchy workaround.

In case it wasn’t clear. All you need to do is run the command line prompt above. This serves as your entry to the Surf Agent Stack (SAS), a complete set of tools covering Skills, APIs, and MCPs that let agents access Surf intelligence on demand and scale with usage. It works with Claude Code, OpenClaw, Codex, or whatever agentic coding environment you use.

Open source and free to start, the Surf Skill brings the crypto data you need straight to your agents without changing the way you work.

And if you’re building something larger and need higher rate limits, the Surf API now offers direct pay-as-you-go access.

Your agent will know what's in here the moment it reads the Skill. But you probably want an overview translated into human, so here it is.

There are 12 domains, but I'll just highlight a few that are hardest to find elsewhere.

Onchain SQL. 80+ ClickHouse tables with sub-second query times across 7 chains from Ethereum to Tempo to HyperEVM. No queue, no SQL prompting. Your agent references the Skill, writes the SQL, Surf executes it, and the data comes back ready to go.

Prediction markets. Surf’s the only platform doing cross-market matching between Polymarket and Kalshi. 934M+ rows of trade data, full orderbook depth, whale tracking, all queryable by your agent on demand. If you have ever tried to compare odds across platforms manually, you understand why this matters.

Social. Smart follower detection, KOL rankings, real-time mindshare tracking. Not raw data straight from the firehose. Structured, scored, and ready for an agent to reason through.

All this and more in a single place. Your agent doesn't need to know where any of it comes from. It just queries Surf and gets an answer.

To celebrate the launch of our Skill, we're giving away $200K in free API credits.

Connect your X, GitHub, and wallet. We score you across six dimensions. Your total takes your best four out of six, so it rewards specialists just like Surf.

Your score maps you to one of 20 sea creatures across five rarity tiers, from Common to Legendary. Your tier determines your credits. Common gets $3 to $5. Uncommon $5 to $10. Rare $10 to $20. Epic $20 to $35. Legendary pushes toward $100. First come, first served.

We built the Surf Skill because the current state of crypto data in agentic workflows is embarrassing. Yes, the data and APIs exist. But getting them all into one place in a format agents can use was a pain for even the most hardcore vibe coders.

Within the next couple years, AI will be how most people interact with crypto data. That shift is already happening. And when it plays out, crypto users will split into two camps. Some want a completely hosted, no-code experience where they can spin up custom crypto apps without touching infrastructure. That is Surf Studio. Others will want to plug Surf intelligence directly into the agents and pipelines they already run. This is SAS.

Two very different workflows. But the thing underneath both of them is the same: the data, the models, the intelligence. That’s what we’re building at Surf.
