The crypto market publishes its data everywhere, in every format.
BytNode is a crypto market-data API that collects all the data of the crypto market environment and delivers it through one REST API, a WebSocket stream and an MCP server adapted for AI agents.
BytNode listens to the whole market at once: order books, trades, derivatives, options, blockchains, ETF flows, macro and sentiment, each at its own pace.
No ten subscriptions, no ten websockets to keep alive.
Three differences you can see before you even sign up.
Crypto data APIs usually start at $29 a month. BytNode starts free, then $6.95 a month.
One coin = $1 a month. Lowest paid API plan, billed annually. Public prices checked on 17 October.

A local agent, the whole market as a tool, your exchanges on consent.
Take the agent as it is, or plug your own client into our MCP server.
How is BTC positioned right now? Funding over the last 24 hours, and open interest?
get_market_datasymbol=BTCUSDT · funding_rate=3api.bytnode.com/mcpget_market_datasymbol=BTCUSDT · oi_change=60 · fear_greed=trueapi.bytnode.com/mcpOver the last three 8-hour settlements, BTCUSDT funding averaged 0.0102 % (about 11.2 % annualised), so longs are paying, mildly. Open interest is up 1.8 % over the past hour while the fear & greed index sits at 54, neutral. Read together: a slow build of long exposure with no sign of crowding. Not a squeeze setup, on either side.
