Why the edge

Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.

Maintenance & community MEXC API +18

Coinbase Advanced Trade API 57

Read as a closed hosted service. The last change to the API itself is the Global Derivatives gateway and INTX retirement of 1 October 2026, 33 days before this check; the Python SDK's v2.0.0rc1 is from 30 September (20 of 30). Dated changes in 90 days are the 1 October migration and the agents entries of 17 and 21 August, which run through Advanced Trade (12 of 20). A public changelog and a CDP Discord; SDK issues not read (8 of 15). Official Python SDK current, the rest samples (12 of 15). SDK CI not read (5 of 10). 20 + 12 + 8 + 12 + 5 = 57.

MEXC API 75

Read as a closed service. Last dated change 23 October 2026 in both the spot and futures logs (30). Spot entries on 14 August, 24 August, 11 September and 23 October 2026, futures on 1 September, 11 September, 19 October and 23 October (20). An API support Telegram group, a ticket form and dated changelogs; GitHub issues not read (10 of 15). The official SDK repository was last pushed in February 2024 while the CLI is current (10 of 15). The CLI ships platform binaries with no dependencies and no public repository or CI; the SDK is stale (5 of 10). 30 + 20 + 10 + 10 + 5 = 75.

Schema & documentation Coinbase Advanced Trade API +16

Coinbase Advanced Trade API 80

Public OpenAPI 3.1 spec (45 paths, 51 operations) and an AsyncAPI document (25). llms.txt and a Markdown twin of every docs page (10). Every operation has a summary and description, some one line, several with multi-sentence guidance for equities (14 of 20). Enums on product_type, granularity, order_status, time_in_forces, order_types, order_side and sort_by, with defaults (13 of 15). Examples in the docs and the sandbox's simulated errors, but the spec documents only a default error referencing grpc.gateway.runtime.Error, with no 4xx or 429 shapes (8 of 15). Paths carry /api/v3, the CDP changelog is dated, and the INTX retirement was announced with a date, but the spec's info.version is 0.1 and the October gateway change has no changelog entry (10 of 15). 25 + 10 + 14 + 13 + 8 + 10 = 80.

MEXC API 64

No OpenAPI found; a Postman collection and the CLI's 25 capability reference files are the nearest machine-readable contract (5 of 25). llms.txt on mexc.com, written for assistants and pointing at the API docs and legal pages (7 of 10). Per-endpoint pages with purpose, parameters and permissions, without when-not-to-use guidance (13 of 20). Typed parameters with enums for order types, statuses and intervals (11 of 15). Examples on each endpoint and a separate error-code page with numeric codes and messages (13 of 15). Versioned API (v3) with a dated changelog of 72 entries to 23 October 2026 (15). 5 + 7 + 13 + 11 + 13 + 15 = 64.

Reliability Coinbase Advanced Trade API +15

Coinbase Advanced Trade API 58

Read with the hosted lines. status.coinbase.com is a Statuspage site with Coinbase Advanced Trade, API, US Derivatives and International Derivatives components (20). The incidents feed we could read runs from 16 September to 3 November 2026. In it Advanced Trade was degraded for 25 minutes on 21 September, the website had a 3-minute major on 14 October, converts were down 1 hour 4 minutes on 26 October, and no incident named the API; 5 August to 15 September was beyond the feed, so minor only for the seven weeks read (15 of 30). No REST rate limit with numbers was found; the older rate-limits page answers 404 and llms.txt lists none, while the WebSocket page gives 8 connections and 8 unauthenticated messages per second per IP (5 of 15). Orders take a client_order_id, but no 429 or Retry-After guidance was found for Advanced Trade (8 of 15). No SLA (0). REST and WebSocket are generally available; the Global Derivatives gateway is a month old and not marked beta (10). 20 + 15 + 5 + 8 + 0 + 10 = 58.

MEXC API 43

Read with the hosted lines. No status page found; status.mexc.com does not resolve and llms.txt points to a maintenance-updates feed (0). No readable incident history (5). Rate limits documented with numbers, 300 weight per 10 seconds per IP, 500 per UID, 12 order requests a second per UID, 100 WebSocket messages a second (15). 429 and 418 carry Retry-After with ban lengths stated, a 5xx is to be treated as unknown rather than failed, an order-test endpoint exists, and newClientOrderId is optional with no idempotency promise (13 of 15). No SLA found (0). Spot and futures are generally available, futures order placement having reopened on 31 March 2026 after being closed since July 2022 (10). 0 + 5 + 15 + 13 + 0 + 10 = 43.

Payments & pricing MEXC API +11

Coinbase Advanced Trade API 20

No machine payment protocol on the API (0). The fee schedule answered a bot check on 3 November 2026, so no per-trade price was read, and the docs give none (0 of 20, unchecked). Six public market endpoints and the sandbox need no key or card (20). A person signs up, passes verification and mints a key in the portal (0). 0 + 0 + 20 + 0 = 20.

MEXC API 31

No machine payment protocol (0). Fees published without login on MEXC's own fee guide (20 October 2026) and a 2024 announcement, with a separate API futures schedule; the fee page itself is drawn by script (16 of 20). Public market data needs no key or card; trading needs a verified and funded account. Judgement call (15 of 20). A person must sign up in a browser, and futures need identity verification (0). 0 + 16 + 15 + 0 = 31.

Agent ergonomics Coinbase Advanced Trade API +9

Coinbase Advanced Trade API 73

Product lists filter by product_type and product_ids with limit and offset, candles take a granularity, but fields cannot be selected and the docs warn that product lists run to hundreds of entries (15 of 25). Cursor pagination with limit on orders and fills, filters by status, product and time (16 of 20). Error codes such as INSUFFICIENT_FUND, ORDER_NOT_FOUND and PERMISSION_DENIED are documented and can be simulated in the sandbox, though the spec gives no shapes (14 of 20). client_order_id on every order; no idempotency key on other writes (16 of 20). Few required fields, an official Python SDK and sample SDKs in three languages, but each request needs a freshly signed JWT (12 of 15). 15 + 16 + 14 + 16 + 12 = 73.

MEXC API 64

Graded on the REST API with the CLI's MCP mode. Responses take limit parameters and the MCP read-only market subset is 22 tools, but a full spot MCP category lists 123 tools (15 of 25). startTime, endTime and limit on history, symbol filters on open orders (14 of 20). Numeric codes with messages, a 30035 order-limit code added 23 October 2026, 5xx guidance (14 of 20). newClientOrderId is optional with no idempotency guarantee; the CLI adds --dry-run and a confirmation step (10 of 20). Few required parameters; SDKs in five languages whose repository was last pushed in February 2024 (11 of 15). 15 + 14 + 14 + 10 + 11 = 64.

Transparency & trust Coinbase Advanced Trade API +9

Coinbase Advanced Trade API 67

The editorial half. A closed service whose user agreement answered a bot check; the OpenAPI spec is public and the Python SDK is open on GitHub (12 of 30). Privacy facts per the coinbase-cdp-agentkit check of 1 October 2026 (Coinbase, Inc., processing countries, retention tied to need without numbers), not re-read (10 of 30). INTX endpoints retired on 1 October 2026 with a dated notice and a read-only grace period (12 of 20). Processing countries and provider categories per the same earlier check, no subprocessor list (8 of 20). 12 + 10 + 12 + 8 = 42.

MEXC API 58

The editorial half. A closed service with a dated user agreement naming MEXC (Comoros) Ltd; the CLI is UNLICENSED on npm (15 of 30). The privacy policy names no entity, states no retention periods and relies on standard contractual clauses for transfers (10 of 30). The changelog flags endpoints as "will be discontinued soon" without dates and the futures log records removals (8 of 20). Third parties are named by category only, with no subprocessor list or data locations (5 of 20). 15 + 10 + 8 + 5 = 38.

Verdicts

Coinbase Advanced Trade API

Advanced Trade has a public OpenAPI spec, keys limited to view, trade or transfer and to one portfolio, and a keyless static sandbox. No REST rate limit is published, the fee schedule, user agreement and country list sit behind a bot check, and an agent that wants an MCP route uses the separate coinbase-mcp listing.

MEXC API

MEXC publishes granular key permissions, per-pair key limits, weighted rate limits with Retry-After and a dated changelog, and its official CLI runs a read-only-capable MCP server with confirmation before any fund movement. There is no sandbox or status page, API futures orders pay a higher fee schedule, and the user agreement excludes the US, UK, EU members and others.

Before you call either

Coinbase Advanced Trade API

  1. Mint a fresh ES256 JWT for every request; tokens expire after 2 minutes and Ed25519 keys are rejected
  2. Send a unique client_order_id on every order and reuse it on retry so a dropped connection does not place a second order
  3. Develop against api-sandbox.coinbase.com first; its responses are static, so do not read prices or fills from it
  4. Use a key with view only, or trade without transfer, and restrict it to a portfolio funded for the agent
  5. For perpetuals call the Global Derivatives JSON-RPC gateway at drb.coinbase.com; the /intx/* endpoints are retired

MEXC API

  1. Use a key limited to SPOT_ACCOUNT_READ and SPOT_DEAL_WRITE, the pairs you trade and your IP addresses; keys without a linked IP expire after 90 days
  2. Start the MCP server as mexc mcp spot --read-only unless the task trades, and never pass --yes; orders and transfers wait for the person's confirmation
  3. Call POST /api/v3/order/test before a live order, since there is no sandbox
  4. On 429 or 418 wait for Retry-After; order placement and cancellation share 12 requests a second per UID, and repeated breaches ban the IP for up to 3 days
  5. Treat a 5xx on an order as unknown, not failed, and query the order before retrying; set newClientOrderId so the order can be found
