## Which one, for what

### MiniMax API (C)

Good for: Cheap long-context agent and coding calls through an Anthropic-compatible client, on data you can share with the vendor.

Ahead on:
- Reliability, 75 against 25
- Schema & documentation, 82 against 58

Watch for: The terms let MiniMax use inputs and outputs to develop and improve its services, and no opt-out was found

### Router.com (Ramp Router) (C)

Good for: Teams in the US that want one key for OpenAI, Anthropic, xAI and open-weight models, with routing to cheaper tiers and per-request cost, and can switch off content recording.

Ahead on:
- Agent ergonomics, 77 against 59
- Security & auth, 66 against 30
- Payments & pricing, 40 against 20
- Maintenance & community, 59 against 45

Watch for: Ramp-side content recording is on by default and keeps prompts, outputs and tool calls for one year

## Verdicts

**MiniMax API.** M3.1 Flash costs $0.15 in and $0.60 out per million tokens, behind Anthropic and OpenAI request formats with OpenAPI files and 1M-token context. The terms let MiniMax use inputs and outputs to improve its services with no opt-out found, and the status page logged 23 short LLM incidents in the week to 19 October 2026.

**Router.com (Ramp Router).** Detailed Markdown docs with typed error codes, per-model capability data and routing an agent can set per request. No OpenAPI document, status page, changelog or published rate limits were found. Signup needs a US business email in a browser, and Ramp records prompts and outputs for a year by default unless switched off.

## Before you call either

### MiniMax API

1. Use the Anthropic-format base URL `https://api.minimax.io/anthropic` for tool calls. The OpenAI-format schema has no `tool_choice` or `response_format`
2. Set `output_config.effort` (or `reasoning_effort`) below `max` for routine calls. M3.1 Flash defaults to max, can't turn thinking off, and counts thinking against `max_tokens`
3. Don't rely on `stop_sequences` or `top_k`. The Anthropic-format endpoint ignores them
4. Back off on 429 and 529 yourself. No Retry-After header is documented
5. Use a pay-as-you-go key for production. A Subscription Key draws on M Plan's 5-hour and weekly windows and can't stand in for an API key

### Router.com (Ramp Router)

1. Switch off content recording in Settings before sending private data. It is on by default and keeps prompts and outputs for a year
2. Read model ids from `GET /v1/models` at runtime. Ids are account-specific, an unknown one is a 404, and Gemini ids need your own Google key
3. Use `POST /v1/responses` with a `models` list for fallbacks. Router stops falling back once a stream has started
4. Set `fallback_timeout` and `provider_timeout`, or `allow_flex_tier: false`, when latency matters. Flex routing is on by default
5. Treat both `401 invalid_api_key` and `401 api_key_deactivated` as a possibly locked key, and stop retrying on `402`
