## Which one, for what

### Gate (C)

Good for: An agent trading spot, futures and earn products in a person's Gate account outside the 35 restricted locations, with a keyless MCP for research and an OAuth MCP or scoped key for trading.

Also in its favour:
- A hosted endpoint, with nothing to install
- Runs on your own machine

Watch for: No status page, incident history or SLA; the terms give no uptime guarantee and cap liability at three months of fees

### Uniswap Trading API (B)

Good for: An agent swapping or bridging tokens from its own wallet on 21 EVM chains, or managing liquidity positions, with routing done for it.

Ahead on:
- Schema & documentation, 90 against 70
- Agent ergonomics, 72 against 66
- Payments & pricing, 40 against 35
- Maintenance & community, 88 against 77
- Transparency & trust, 55 against 49

Also in its favour:
- Free to start without a card

Watch for: No official MCP server; the registry's Uniswap entries are third parties


## Why the edge

### Schema & documentation: Uniswap Trading API +20

- Gate (70): No public OpenAPI file was found, though the SDKs are generated and the MCP tools carry typed parameters per the tool reference; the hosted tools' JSON Schema could not be read without a session (12 of 25). The whole REST and WebSocket documentation is downloadable as Markdown and the agent guide is a plain page (10). The tool reference gives one line and the main parameters per tool, the API reference a description per endpoint, no when-not-to-use guidance (12 of 20). Required flags, enums for side, type and time_in_force (11 of 15). Examples per endpoint and a labelled error body with a fixed label list the docs tell you to branch on instead of messages (13 of 15). A versioned changelog, v4.106.177 on 2 November 2026 (12 of 15, since entries are terse). 70.
- 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.

### Maintenance & community: Uniswap Trading API +11

- Gate (77): Read as a hosted service with open-source MCP packages. The API changelog's latest entry is 2 November 2026 and gate-skills was pushed 3 November (30). 40 dated changelog entries since 5 August 2026 (20). developer@gate.com, a help centre and issue trackers on gate-mcp and gate-skills, replies not checked (12 of 25). In the official MCP registry under io.github.gateio-dev, a GitHub namespace rather than gate.com, and official SDKs current (10 of 15). The local package has a publish workflow and no test workflow in CI, and its last tag is 16 April 2026 (5 of 10). 77.
- 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.

### Agent ergonomics: Uniswap Trading API +6

- Gate (66): Read for the API with the hosted MCP beside it. The MCP is split by endpoint (58 public tools on /mcp, 400 or more on /mcp/exchange, smaller info and news servers) and the local package filters by module and read-only flag, which stands in for toolsets (5 of 25 for the trading server, 10 added back). Pagination by page and limit, from and to timestamps, status filters (15 of 20). Error labels such as INVALID_SIGNATURE, REQUEST_EXPIRED, IP_FORBIDDEN and READ_ONLY name the recovery (15 of 20). The `text` order identifier makes retries safe; the local server's source sets no readOnlyHint or destructiveHint and the hosted annotations are unread (8 of 20). Three required fields on a spot order, SDKs in seven languages and a CLI (13 of 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.

### Transparency & trust: Uniswap Trading API +6

- Gate (49): The editorial half. A closed hosted service with a clear user agreement that names no company; the MCP packages are MIT (12 of 30). The privacy policy names a DPO address and categories of recipients, with no retention numbers and no named subprocessors (12 of 30). The changelog records breaking changes such as the amend endpoint path move of 16 October 2026 with no notice period or policy (8 of 20). Transfers outside the user's jurisdiction are disclosed with no locations or provider names (5 of 20). 37.
- Uniswap Trading API (55): The editorial half. The API is closed under API Terms of Use that answered 403; the SDKs and uniswap-ai are MIT and the protocol contracts are open source (15 of 30). No privacy policy read (app.uniswap.org draws by script) and nothing in the docs on retention of quotes or wallet addresses (0 of 30). A published sunset policy of at least 30 days, ideally 60, with dated notices such as the Universal Router 2.0 and 2.1.1 sunset of 21 October 2026 (20). No subprocessors or data locations (0 of 20). Total 35.

### Payments & pricing: Uniswap Trading API +5

- Gate (35): No machine payment protocol (0). The fee page's table loads after login; help centre and learn articles give the VIP 0 spot rates (15 of 20). Market data over REST and the public MCP needs no account and no card (20). A person registers, verifies identity and mints the key or approves the grant in a browser (0). 35.
- Uniswap Trading API (40): No machine payment protocol on the API's endpoints; the `pay-with-any-token` skill lets an agent pay other services' 402 challenges by swapping, which earns nothing here (0). The API is free, stated in the FAQ and the 16 April 2026 post, and integrator fees are capped at 500 bips (20). No card and no plan (20). A person creates an account in the dashboard to get a key (0). Total 40.

## Verdicts

**Gate.** Gate runs official hosted MCP servers with keyless market data and OAuth-scoped trading, a local stdio server with a read-only switch, per-endpoint rate limits with headers and a futures testnet. There is no status page, SLA or OpenAPI file, the fee table needs a login, the MCP host is a separate domain, and the terms name no company.

**Uniswap Trading API.** The Trading API is free, documented by an OpenAPI file with stable error codes, holds no keys since the caller signs every swap, and posts sunset notices 30 days ahead. There is no official MCP server, status page or sandbox, the key is a plain header secret at 6 requests a second, and the API terms refused our reader.

## Before you call either

### Gate

1. Start on https://api.gatemcp.ai/mcp for prices and order books with no credential; switch to /mcp/exchange only when the person has approved the OAuth grant with the narrowest scopes
2. For a key-based route, create a key on a dedicated sub-account with read-only on every group but the one the task needs, withdrawal disabled and an IP allow-list; changes take up to 5 minutes
3. Put a unique `text` value starting with t- on every spot order and reuse it on the retry; read the order back before placing again
4. Read X-Gate-RateLimit-Requests-Remain and stop at zero; spot order placement is capped at 10 a second and withdrawals at 1 per 3 seconds
5. Rehearse futures logic on api-testnet.gateapi.io with TestNet keys; there is no spot testnet

### Uniswap Trading API

1. Call `/check_approval` first, then `/quote`; if `permitData` is non-null sign it as EIP-712 and send `signature` and `permitData` together to `/swap` or `/order`, never one without the other
2. Route on the quote's `routing`: `CLASSIC`, `WRAP`, `UNWRAP` and `BRIDGE` go to `/swap`, `DUTCH_V2`, `DUTCH_V3` and `PRIORITY` to `/order`, `CHAINED` to `/plan`
3. Refresh any quote older than 30 seconds before broadcasting, and on 429 pause every request from the key before retrying
4. Retry unchanged only on `UpstreamTimeoutError`; `NoRouteFoundError` and `QuoteAmountTooLowError` need a different amount, token or `protocols` list
5. Send `X-Agent-Info` with `decision_origin: autonomous` and keep `x-api-key` server-side
