Overview
Crypto market data for AI agents — one MCP server, REST API and WebSocket API with live prices, derivatives, options, order flow, on-chain, sentiment, news and catalysts.
f1ow gives Claude, ChatGPT, Cursor, VS Code or your own agent the whole crypto market through one endpoint. Prices, perpetual derivatives, options, order flow, whale positioning, on-chain activity, sentiment, news and catalysts are drawn from many sources and reconciled into one read. That read is available as 39 tools.

Three ways in
MCP server
Point Claude, ChatGPT, Cursor or VS Code at one URL. The model discovers every tool and calls them on its own.
REST API
Every tool is a plain HTTP resource with JSON responses and an OpenAPI 3.1 spec. Bring your own code.
WebSocket API
JSON-RPC 2.0 over a socket, with subscriptions that push only when a result changes.
All three share the same tools, the same API key and the same balance. Agents without an account can pay per call with x402.
What you can ask
Composite reads that assemble many sources into one answer: market regime, positioning, setup scans, token dossiers and trade-plan checks.
Quotes, candles, paged history, market breadth, movers and coin metadata.
Perpetual funding, open interest, liquidations and taker flow across venues.
Chains, implied volatility, positioning, modeled gamma and risk-neutral expiry odds.
Order books, evidence-graded price levels, whale positions and cohort flow.
Multi-timeframe indicators computed from candles.
Fear & Greed, social attention and live posts.
Cited news search and regulatory filings.
ETF flows, economic and crypto calendars, and prediction-market odds.
Chain-level activity, TVL and fees.
A UTC clock, so an agent can judge how fresh a read is.
The composite research tools assemble many reads at once:
- Market Regime tells you what kind of market you are trading in.
- Positioning shows who is crowded, fragile or trapped on one coin.
- Opportunity Scan scans liquid coins for rule-based setups.
- Trade Plan Review checks an entry, stop and target, sizes the position and replays a placed trade.
The rest are focused building blocks: quotes, candles, funding, open interest, liquidations, order books, options chains and more. See the tool reference.
Who it is for
AI traders
Ask Claude or ChatGPT about the market in plain English and get answers grounded in live data.
Trading bot developers
Feed your strategy funding, open interest, liquidations and levels from one REST or WebSocket API.
Agent builders
Give an autonomous agent a market-data toolset with typed schemas, pay-per-call and machine-readable discovery.
What it is not
f1ow is read-only. It observes the market and returns snapshots. It never places orders, holds funds or watches positions for you. Setup scans and trade plans are rule-based planning geometry, not personalized advice or a promise of returns.
