## Which one, for what

### Bithumb Open API (D)

Good for: KRW-market trading for agents acting for a verified Korean account, with a vendor-built MCP server, CLI and skills.

Also in its favour:
- Runs on your own machine

Watch for: No sandbox or testnet; every order uses real funds

### Deribit (C)

Good for: An agent trading crypto options, dated futures and perpetuals for an institutional or retail Deribit account, and anyone migrated from Coinbase International Exchange.

Ahead on:
- Reliability, 45 against 34
- Schema & documentation, 88 against 64
- Agent ergonomics, 74 against 67
- Payments & pricing, 25 against 15

Watch for: No official MCP server, and the GitHub organisation has no public repositories, so no official SDK in any language


## Why the edge

### Schema & documentation: Deribit +24

- Bithumb Open API (64): No OpenAPI found; the reference is a readme.io site with Markdown twins, and the MCP tool schemas weren't read since the server's source isn't published (5 of 25). llms.txt on apidocs.bithumb.com (10). Reference pages state purpose and the skills say when to use each module and when not to (15 of 20). Typed parameters with enums for side, order type and time in force (10 of 15). Examples in several languages and an error-code page with names, statuses and meanings (12 of 15). Versions per endpoint (v1, v2, v2.1.5) and notices with effective dates (12 of 15). 5 + 10 + 15 + 10 + 12 + 12 = 64.
- Deribit (88): OpenAPI 3.0.0 for the whole JSON-RPC surface (Deribit API 2.1.1, about 1.4 million characters) plus AsyncAPI files for the WebSocket side (25). llms.txt with production and upcoming indexes, and a Markdown twin of every page (10). Each operation has a description such as "Places a buy order for an instrument." with parameter notes, and the articles say when to use WebSocket subscriptions over polling, but the reference seldom says when not to use a method (13 of 20). Parameters are typed with enums (order `type` has eight values, `time_in_force` four) and required flags, with `amount` or `contracts` as a documented either-or (13 of 15). Every reference page carries an example request and response, and the errors page lists about 159 codes with retry guidance, though most operations document only a 200 response and the smaller error tables disagree with the full one on two codes (12 of 15). A versioned path (/api/v2), a production and an upcoming docs branch, and a dated changelog of 64 entries since 21 January 2020 (15). Total 88.

### Reliability: Deribit +11

- Bithumb Open API (34): Read with the hosted lines. No status page found on apidocs.bithumb.com or in llms.txt; wallet-status and notices endpoints stand in (0). No readable incident history, though two notices record a public WebSocket interruption and a brief service break (5). Rate limits documented per category with numbers, updated 27 October 2026 (15). A breach is described only as a temporary restriction, with no status code, header or Retry-After, and no client order id or idempotency key is documented; 422 order_not_ready and 500 server_error say to retry later (4 of 15). No SLA found (0). The API is generally available; the MCP server and CLI are at 0.8.5 (10). 0 + 5 + 15 + 4 + 0 + 10 = 34.
- Deribit (45): Read with the hosted lines on the JSON-RPC API. status.deribit.com did not resolve for our reader on 3 November 2026 and Coinbase's status page showed no Deribit component, so no status page is scored, with the unchecked line below (0). No readable history (5). Rate limits are documented with numbers, 50,000 credits per sub-account refilled at 10,000 a second, and matching-engine tiers of 5 to 30 requests a second by 7-day volume (15). Error 10028 ends the session and the errors page says to back off exponentially; 10040 means retry; the 6 May 2026 release added a `nonce` for idempotent orders (15). No SLA found (0). The API is generally available; only Starbase is limited to selected clients (10). 0 + 5 + 15 + 15 + 0 + 10 = 45.

### Payments & pricing: Deribit +10

- Bithumb Open API (15): No machine payment protocol (0). The fee page timed out on every attempt, so no price is recorded (0 of 20, unchecked). Public market data needs no key, card or account; trading needs a verified Korean account. Judgement call (15 of 20). A person must sign up, pass identity checks and issue keys in the browser (0). 0 + 0 + 15 + 0 = 15.
- Deribit (25): No machine payment protocol (0). The fee schedule is on support.deribit.com, which answered 403; Deribit's own posts give VIP4 to VIP7 taker fees and the 0 bps linear options maker fee, so partial prices are public but the lowest tier is unchecked (5 of 20). Public market data needs no key and the test environment is free, with no card anywhere (20). A person signs up in a browser with identity checks before any key exists (0). Total 25.

### Agent ergonomics: Deribit +7

- Bithumb Open API (67): Graded on the REST API with the MCP server. 41 tools in all, selectable by module, so 15 for 11 to 30 or more and 8 added back for the module switch (23 of 25). Candle counts, order paging and a 200-market cap on the ticker (13 of 20). Stable error.name values with retry guidance for order_not_ready and server_error (14 of 20). No client order id or idempotency key documented; the CLI's per-profile read-only flag, the MCP --read-only flag and the skills' read-only gate help, and readOnlyHint annotations weren't checked (9 of 20). Few required parameters, but no official SDK beyond the CLI and a CCXT guide (8 of 15). 23 + 13 + 14 + 9 + 8 = 67.
- Deribit (74): An API, read for response sizing. `public/get_order_book` takes `depth`, `get_instruments` filters by currency and kind, and history methods take `count` and `offset`, though `get_instruments` returns every instrument for a currency and costs 10,000 credits (18 of 25). Count and offset pagination, time ranges on trade and transaction logs, and WebSocket channels with interval and depth options (16 of 20). Numeric error codes with short names, a `wait` value on some errors, and sample code that branches on them (18 of 20). A `nonce` on orders since May 2026 returns the existing order on retry, a `label` lets an agent find its own orders, and 10040 marks the calls safe to retry; no MCP annotations apply (16 of 20). Few required parameters and sensible defaults (limit and good_til_cancelled), but no official SDK in any language, so every caller signs and frames JSON-RPC itself (6 of 15). Total 74.

## Verdicts

**Bithumb Open API.** Bithumb runs an official local MCP server with 41 tools, module selection and a read-only flag, beside a CLI with per-profile read-only gating and six agent skills, over an API with scoped one-year keys and a mandatory IP list. There is no sandbox, no status page, no documented 429 behaviour, and the fees and terms couldn't be read.

**Deribit.** Deribit's JSON-RPC API has scoped keys with IP and expiry limits, asymmetric signing, an OpenAPI file, numeric rate limits and a 64-entry changelog. There is no official MCP server or client library, the fee schedule, terms and privacy policy sit on a support site that refused our reader, and the status page did not resolve.

## Before you call either

### Bithumb Open API

1. Ask for a key with asset and order inquiry plus order placement only, never withdrawals, with your IP registered; keys expire after one year and a wrong IP answers 401 NotAllowIP
2. Start the server with `--modules market,account,trade --read-only` for analysis and drop `--read-only` only when the person asks to trade; deposit and withdraw modules stay off
3. Prefer the `bithumb` CLI for writes, as the skills do, and check `bithumb config show --json` for a read-only profile before any order
4. Keep the ticker's markets parameter at 200 or fewer, batch orders at 30 and cancels at 30 per request, and stay under 140 private calls a second per category
5. Retry 422 order_not_ready and 500 server_error after a pause; there is no sandbox, so start with the smallest order the market allows

### Deribit

1. Create the key with `trade:read_write` and `wallet:none`, an `ip:` limit and an `expires` value; keep `account:read` unless the task edits subaccounts
2. Authenticate with `client_signature` or an Ed25519 key over WebSocket rather than `client_credentials` over HTTP, which puts the secret in the URL
3. Watch the `limits` field of `private/get_account_summary` and back off on error 10028; a session that runs out of credits is closed and must reconnect
4. Send a `nonce` with orders so a retry after a timeout does not place a second order, and treat `order_not_found` on cancel as a possible fill
5. Develop against https://test.deribit.com/api/v2 first; production and test need separate accounts and keys
