Bybit vs Uniswap Trading API

Bybit 66

Read as a hosted service with an open-source MCP server. The MCP package shipped 2.1.26 on 30 October 2026 and the V5 changelog's latest entry is 29 October (30). 31 npm versions since 16 April 2026, 11 of them in the last 90 days, and 24 changelog entries in the same window (20). The trading-mcp repository has 4 open issues and 18 forks; whether issues get answers was not checked, and the API has no public forum we could read (10 of 25). Not in the official MCP registry (0). The package has four dependencies, no install scripts, a publish workflow and no test workflow (6 of 10). 66.

Uniswap Trading API 88

Read as a closed hosted service. The newest changelog notice is dated 22 October 2026 (30). Notices of 20 August, 21 September and 22 October 2026, three in 90 days (20). A help form for developer support that says it won't debug integrators' code, and uniswap-ai with 6 open issues and a push on 26 October (14 of 25). Official TypeScript SDKs current (@uniswap/v4-sdk 2.4.4 with provenance) and the uniswap-ai skills, though no client for the API itself; no MCP registry entry (15). Trusted publishing with provenance on npm, CI and lint hooks on uniswap-ai (9 of 10). Total 88.

Bybit 73

No OpenAPI or other machine-readable contract for the REST API; the MCP server's 398 tools have zod schemas turned into JSON Schema, so the contract exists for the MCP surface only (12 of 25). No llms.txt; the docs are a public Docusaurus repository (bybit-exchange/docs) whose MDX source an agent can read (5 of 10). The MCP tool descriptions state purpose, rules and an agent hint per tool, and the API reference gives one page per endpoint (15 of 20). Parameters are typed with enums such as category and orderType and required flags (12 of 15). Request and response examples on each endpoint page and an error code page of about 750 codes with text (14 of 15). A dated changelog with 24 entries in the last 90 days, versioned V3 to V5 (15). 73.

Uniswap Trading API 90

OpenAPI 3.0 file (Token Trading 1.0.0) for the Trading and LP APIs, about 33 paths with x-internal markers on the margin and 4337 operations (25). llms.txt, llms-full.txt and a Markdown twin of every docs page (10). Operation summaries are one line, but the guides say which routing types go to /swap, /order and /plan, when UniswapX quotes are returned and when a 404 means change the request (14 of 20). Enums for routing types, urgency and position statuses, required fields and bounded integers such as limit 1 to 20 (12 of 15). Examples on every guide page and error schemas for 400, 401, 404 and 429 with a stable errorCode enum and per-code retry advice (14 of 15). A /v1 path, a changelog with posted and effective dates and a 30-day minimum sunset policy (15). Total 90.

Bybit 66

Read for the API with the MCP server beside it. The MCP server has 398 tools in one list with no toolset, module or read-only switch (5 of 25, nothing added back). V5 reads take limit and cursor and category filters (15 of 20). retCode and retMsg on every response with a code list an agent can branch on, though create-order answers before the order is final and the docs say to confirm over WebSocket (14 of 20). orderLinkId makes order retries safe and every MCP tool carries readOnlyHint and destructiveHint (17 of 20). Five required fields on an order, official SDKs in Python, Go, Java and .NET (15). 66.

Uniswap Trading API 72

An API, read for response sizing. Quotes and calldata are compact and /tokens takes a limit; the quote can carry the swap calldata to save a call (20 of 25). GET /orders and GET /swaps poll status by id, /swappable_tokens and /tokens filter by chain and sort, with little pagination elsewhere (12 of 20). Stable errorCode values with a detail string and a requestId, and the docs say which codes to retry (18 of 20). No idempotency key; a swap is a signed transaction whose nonce prevents a double spend, and the docs warn about nonce collisions with pending transactions (12 of 20). Few required fields on /quote, defaults for slippage and urgency, but no official client library for the API and signing needs ethers.js, viem or web3.js (10 of 15). Total 72.
