Is this your product? Claim it to see how agents find it: lookups through the API, MCP and letme, the comparisons it's in, and what people search for in Exchanges. Free, and it never changes the grade. Or verify it, or log in if it's already claimed.

Assessment. Upbit's Open API has a mandatory IP allow-list, scoped keys with a default withdrawal lock, per-group rate limits with 429 and 418 signalling, an order-test endpoint, official SDKs, a CLI and agent skills with a CONFIRM gate. There is no MCP server, sandbox or status page, and the fees and terms sit on a host our crawler may not read.

From our research 12 facts checked against the vendor's pages
Surface listed
The Korean Open API (REST at api.upbit.com and WebSocket) read from docs.upbit.com, its llms.txt and Markdown twins, the upbit-official GitHub organisation, npm and the MCP registry on 3 November 2026. No account was made, no private endpoint was called and the CLI was not run
MCP server
None found. Looked in the developer centre's AI agent section (SDKs, CLI, Skills, Strategy Toolkit, CCXT), the upbit-official GitHub organisation (six repositories) and the official MCP registry, whose only upbit entry is a third party's io.github.mrfentmen/upbit-mcp (stdio, 21 September 2026). solangii/upbit-mcp-server and BrainDAO/mcp-upbit are also third-party
Key permissions
Functions chosen at issuance (the docs name withdrawal and say at least one must be picked; the full list is on the issuance screen); a mandatory public IPv4 allow-list; withdrawal safe-lock on by default for keys with withdrawal permission, lifted only in the app; up to 10 keys on the main pocket and 5 per sub-pocket; secret shown once; expiry period not stated. Withdrawal address registration is a separate step in the account
Rate limits
Quotation 10 a second per IP per group (market, candle, trade, ticker, orderbook). Exchange per pocket, default 30 a second, order 12 a second, order-test 8 a second, cancel-all 1 per 2 seconds; travel-rule checks 1 per 10 minutes per deposit. WebSocket 5 connections a second, 5 messages a second and 100 a minute per connection; requests with an Origin header 1 per 10 seconds. 429 on a breach, 418 after repeats with a block duration, Remaining-Req header (min deprecated). Updated 7 October 2026
Testnet
None. POST /v1/orders/test validates an order without placing it (v1.6.1, 27 October 2025)
Countries
The Korean exchange, with KRW, BTC and USDT markets, Korean identity verification and 2FA for keys and a KRW bank account for fiat. Upbit Singapore, Indonesia and Thailand have separate docs at global-docs.upbit.com. No served or excluded country list was readable; the terms are on upbit.com, which disallows our crawler
Fees
Unchecked. The fee page is on upbit.com, whose robots.txt disallows every path
FIX and WebSocket
WebSocket public streams (ticker, trade, orderbook, candle) and private streams (my order, my asset, announcements, technical indicators for KRW markets). No FIX found in the docs
Terms on automation
Unchecked. The Open API Terms of Use are on upbit.com. The technical support notice says sample code is for reference at the user's own responsibility and refers to those terms; the AI guide says commercial use or redistribution of the docs may breach them
Agent tooling
SDKs (Python upbit-sdk, TypeScript, Go; Apache-2.0 on GitHub), CLI @upbit-official/upbit-cli 1.0.0, Skills upbit-official/upbit-agent-skills for Claude Code and Cursor with a CONFIRM gate, and a backtest-only Strategy Toolkit in beta. Pocket API supported across them
Changelog
Ten notices on docs.upbit.com, dated items among them the SDK v1.1.0 (20 October 2026), the rate-limit page (7 October 2026) and the path-format change effective 16 November 2026

Facts verified 3 November 2026 from vendor docs, repositories and package registries. JSON · Markdown

Strengths

  • Keys need a registered public IP, carry only the chosen functions and get a withdrawal safe-lock by default that only the mobile app lifts
  • Rate limits published per group with numbers, a Remaining-Req header on every response, 429 then 418 with a stated block length
  • POST /v1/orders/test checks an order and the pair's state at no cost, and the skills run it before a live order
  • Official Python, TypeScript and Go SDKs at v1.1.0 (20 October 2026), a CLI with JSON output and agent skills that require a typed CONFIRM before any write
  • Notices carry effective dates, such as the path-format change of 16 November 2026

Weaknesses

  • No MCP server; the agent route is the CLI through skills, which need a terminal
  • No sandbox or testnet beyond the order-test endpoint, and no status page or SLA
  • Keys can only be issued on the PC web site after Korean identity verification and 2FA, and the exchange serves the Korean market
  • The fee schedule, user terms and Open API terms are on upbit.com, which disallows every crawler path, so none is recorded first-hand
  • The SDK licence page says the SDK material is not open source while the GitHub repositories carry Apache-2.0

Before you call it notes for agents

  1. Ask the person for a key with only the functions the task needs and your server's public IPv4 address registered; a private or unregistered IP is refused
  2. Sign every request with a fresh JWT (HS512, new nonce, SHA512 query hash) and branch on error.name, not error.message
  3. Run POST /v1/orders/test before a live order; it costs nothing and shares the 8-a-second order-test group
  4. Read Remaining-Req and keep orders under 12 a second per pocket; on 429 wait for the next second and on 418 wait out the stated block
  5. Leave the withdrawal safe-lock on unless the person lifts it in the app, and send paths with single slashes and no trailing slash before 16 November 2026

Terms and privacy, as read

Terms of service none to read

TL;DR We found no terms of service published for this product, so there is nothing to read and the check scores 0.

Privacy policy gives no date, states 1 of 8

TL;DR Gives no date. States 1 of the 8 things a reader expects, and we didn't find what is collected, how long data is kept, who else gets the data, whether data is sold, people's rights or where data goes. The rules found no clause to flag.

A reading by a fixed set of rules, each answered with the vendor's own sentence. It isn't legal advice, a rule can miss a clause or misread one, and the document itself is what binds. How it's read and scored.

Dunamu Inc. is named as the licensor in the Upbit Developer SDK License v1.0 and as the company in the developer centre's privacy policy V1.5 (from 18 May 2026).

upbit.com/robots.txt disallows every path for User-agent * (a second group adds /terms_and_policy and others), allowing only Googlebot, MSNBot, Yeti and Daumoa; sg.upbit.com and www.dunamu.com do the same. The user terms, the Open API terms, the fee schedule and security.txt on those hosts were therefore not fetched; the terms URL is left empty.

docs.upbit.com/robots.txt allows everything but edit, login and api-next paths and points to llms.txt, with Content-Signal ai-train=yes, search=yes, ai-input=yes.

RDAP gives upbit.com a registration date of 10 January 2004.

No status page found; the API has a service-status (wallet status) endpoint and an announcements WebSocket stream.

Checked 2026-11-03 against the vendor's own pages and the domain registry. Provenance is half of Transparency & trust.

Dunamu Inc. on GitHub

Researched 3 November 2026 from public pages. No first-hand page naming a founder or executive could be read. www.dunamu.com, upbit.com and sg.upbit.com disallow every path for our crawler, so the company pages that would name Dunamu's leadership were not fetched. The developer centre's privacy policy V1.5 names Dunamu Inc. as the company and a privacy officer in its privacy team, which is not a key role, so nobody is listed. Ownership is recorded as unknown because no page read states whether Dunamu is privately held or listed, and no investor search was made since the company's own pages were off limits. Shown for information, not part of the grade yet. People's accounts link to their own profiles; check them before you rely on one.

Notable

  • MCP server, none found. The developer centre's AI agent section covers SDKs, a CLI, agent skills and a backtest-only strategy toolkit and never mentions MCP; the upbit-official GitHub organisation has six repositories and none is an MCP server; the official MCP registry lists only a third party's io.github.mrfentmen/upbit-mcp, and other third-party servers (solangii/upbit-mcp-server, BrainDAO/mcp-upbit) are not Upbit's source
  • Upbit Agent Skills (upbit-official/upbit-agent-skills, installed with npx skills add) drive the upbit CLI from Claude Code or Cursor and require the person to type CONFIRM on its own line before any order, cancellation, withdrawal, KRW deposit, address creation or pocket transfer; order tests and dry runs need no confirmation source
  • Rate limits, updated 7 October 2026: quotation groups 10 requests a second per IP; exchange groups per pocket, 30 a second by default, 12 a second for orders, 8 a second for order tests and 1 per 2 seconds for cancel-all; WebSocket 5 connections a second and 5 messages a second or 100 a minute per connection. 429 on a breach, 418 with a block duration after repeats, and a Remaining-Req header on every response source
  • No sandbox. POST /v1/orders/test validates an order and the pair's state without placing it, at no fee, released as v1.6.1 on 27 October 2025 source
  • A notice effective 16 November 2026 makes requests with doubled or trailing slashes in the path return an error and tells clients to branch on error.name rather than error.message source
  • Official SDKs for Python (upbit-sdk, Python 3.9 or later), TypeScript and Go, licensed Apache-2.0 on GitHub, v1.1.0 on 20 October 2026; the developer centre's SDK licence page says Dunamu's SDK material is under the Upbit Developer SDK License v1.0, which "is not an open-source license" and bars business use source
  • The CLI @upbit-official/upbit-cli 1.0.0 (1 September 2026, Apache-2.0, Go, also installable with go install) takes keys from UPBIT_ACCESS_KEY and UPBIT_SECRET_KEY and prints json, jsonl, yaml or raw with --transform (GJSON) and --max-items source
  • The developer centre's privacy policy V1.5 (from 18 May 2026) names Dunamu Inc., keeps complaint records for 3 years, Google Analytics data for up to 26 months, and transfers complaint data to Zendesk in Japan source
  • upbit.com and sg.upbit.com disallow every path for our crawler, so the fee schedule, the user terms, the Open API terms of use and security.txt were not read; the AI guide warns that commercial use or redistribution of the docs may breach the Open API Terms of Use source
  • Separate docs at global-docs.upbit.com cover Upbit Singapore, Indonesia and Thailand (SGD, IDR and THB markets); this listing is the Korean exchange source

An order-test endpoint and a CONFIRM gate in the skills; an order identifier for idempotent placement was not checked (11 of 20).

  1. Graded 54.7 C methodology v0.7

Fix list 18 items, the biggest gain first

Everything this grade says the listing lacks, from the reasons above, the checklist, the provenance checks, the deductions, what we couldn't check and what the review panel asked for, with the steps, ready to paste into a coding agent working on Upbit Open API. A fix counts at the next check, once it's public.

What we couldn't check

  • Kind http-api: the REST and WebSocket API is the only hosted surface; the SDKs, CLI and skills are clients of it. No MCP server found after reading the AI agent section, the GitHub organisation and the registry.
  • unchecked: the fee schedule, the user terms, the Open API Terms of Use, security.txt and the main privacy policy, all on upbit.com (or sg.upbit.com), whose robots.txt disallows every path for our crawler. Payments pricing and the terms' automation clauses are scored absent for that reason.
  • unchecked: the full permission list on the key issuance screen (the docs name withdrawal and say at least one function is chosen), the key expiry period, an order identifier for idempotent placement, and the CLI's and skills' source beyond the docs (no clone made).
  • firstReleased is 27 October 2025, the v1.6.1 release of the order-test endpoint, the earliest first-hand date found; the Open API itself is years older and the developer centre gives no launch date. lastRelease is 20 October 2026, the SDK v1.1.0 notice.
  • The SDK licence page (Upbit Developer SDK License v1.0, not open source, no business use) and the GitHub repositories (Apache-2.0) disagree on the SDK licence. Recorded in transparency, not deducted; a person may want to ask which governs.
  • Humans: no person with a key role on a readable first-hand page; www.dunamu.com and upbit.com disallow our crawler. The developer centre privacy policy names a privacy officer, not a leader. Ownership unknown from the pages read; no investor search was made for the same reason.
  • Our own products. It doesn't do LocalGhost's or letme's job.

Pricing & changes

Pay per use Pay per use Trading fees per fill. The fee schedule is on upbit.com, whose robots.txt disallows every path for our crawler, so no rate is recorded. Public quotation endpoints need no key and no account (https://upbit.com/robots.txt, checked 2026-11-03).

  2. Tell us where it is

    We read it once now and again every week. If the link is missing two weeks in a row the listing says so, and a later check puts it back.

Agents send the same to POST /api/v1/verify as {"slug": "upbit", "url": "…"}, or call the verify_listing tool at /mcp. Ten checks an hour from one address. What we check. To announce the listing, get sharing assets for social media.

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
