Is there a Bithumb MCP server?

Yes. Bithumb publishes an official MCP server, @bithumb-official/bithumb-mcp, as part of its AI Trade Kit, with documented setup for Claude Code, Codex, Cursor and other clients. You can also connect Bithumb directly through Jentic: your agent gets the full 24-endpoint surface from the spec without loading another server's tool definitions into its context, your access key and secret key are held by your own Jentic One instance instead of an MCP config entry or a shell profile variable, and your rules decide which operations the agent may call.

What authentication does the Bithumb API use?

Private endpoints take an Authorization: Bearer header carrying a JWT that the caller signs for each request from a Bithumb API access key and secret key, using HMAC-SHA256 over access_key, nonce and timestamp claims, plus a SHA-512 query_hash where the request has query parameters. There is no long-lived static token to paste. Public market data endpoints need no credential at all: 13 of the 24 operations are open. Through Jentic the access key and secret key are held encrypted by your own Jentic One instance and used at execution time.

Can I read KRW market data without an account?

Yes. The /public/ticker, /public/orderbook, /public/transaction_history, /v1/market/all, /v1/candles/* and /v1/ticker endpoints are all public. They return Korean Won pair data without authentication, so a research pipeline can pull tickers and candles without onboarding.

What are the rate limits for the Bithumb API?

Bithumb documents per-second request caps by API type: 150 requests per second for the Public API and 140 for the Private API, with order-related requests such as create and cancel capped at 10 per second. Exceeding a cap gets the request throttled, so back off with exponential delay before retrying.

How do I get a BTC_KRW price through Jentic?

Install Jentic One, import Bithumb from the API Directory, then search for 'get btc krw ticker', load the /public/ticker operation schema, and execute with order_currency=BTC and payment_currency=KRW. The response close field is the latest trade price. On the v1 surface the same figure comes from /v1/ticker with the markets query parameter set to KRW-BTC.

What candle intervals does the v1 API support?

The v1 candles surface exposes minute, day, week, and month endpoints: /v1/candles/minutes/{unit}, /v1/candles/days, /v1/candles/weeks, and /v1/candles/months. The minute endpoint accepts a unit path parameter for the granularity, with an enum of 1, 3, 5, 10, 15, 30, 60 and 240 and a default of 1.

Can I limit what my agent is allowed to do with the Bithumb API?

Yes. Because you run Jentic One yourself, you decide which Bithumb operations the agent may call, so you can allow only the public read endpoints such as /public/ticker/{order_currency}_{payment_currency}, /public/orderbook, and /v1/market/all while withholding the authenticated v1 and v2 trading operations. Trading and account actions are excluded unless you explicitly add them, and your bearer token is injected at execution time only for the operations you enable. This keeps a market-data agent scoped to reading KRW tickers and candles with no ability to place orders.
