## Which one, for what

### ROOK (C)

Good for: A wellness, insurance, corporate wellness or remote monitoring product that wants normalised wearable data pushed to its backend, with plan prices it can see up front.

Ahead on:
- Reliability, 75 against 67
- Payments & pricing, 25 against 20

Watch for: Credentials are one client UUID and secret per environment, sent by Basic auth, with no scopes or rotation documented

### Terra API (B)

Good for: A fitness, wellness, insurance or research product whose users connect consumer wearables and apps, and an agent that needs to read one user's sleep, activity or body data through MCP.

Ahead on:
- Schema & documentation, 89 against 74
- Agent ergonomics, 78 against 49
- Security & auth, 65 against 32

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: No free tier. Sign-up asks for a plan and billing details, and Quick Start starts at $499 a month with a 30-day money-back guarantee

## Verdicts

**ROOK.** Graded on the REST API. A public OpenAPI file, a free Sandbox from the self-serve portal, published plan prices and a dated changelog. Credentials are one client UUID and secret per environment with no scopes, 429 handling isn't documented, the API is meant for occasional queries rather than bulk reads, and no SOC 2 report or security contact was found.

**Terra API.** Graded on the Unified API and the Terra AI MCP server. A public OpenAPI 3.1 spec, llms.txt, per-user rate limits with Retry-After, and scoped admin tokens with approvals. Access starts at $499 a month with billing details at sign-up, the data API key has no scopes, and API key requests failed for 2 hours 38 minutes on 7 August 2026.

## Before you call either

### ROOK

1. Send HTTP Basic auth with client_uuid as the username and the secret key as the password, plus a User-Agent header, or the WAF returns 403
2. Use https://api.rook-connect.review for Sandbox and https://api.rook-connect.com for production. Each has its own credentials
3. Read health data from the data webhook. Use the API only for occasional queries, and stay under 60 requests a minute
4. Deduplicate summaries on document_version and datetime. ROOK resends a summary with a higher document_version when it changes
5. Call POST /api/v1/user_id/{user_id}/data_sources/revoke_auth to end a connection. Some providers take hours to stop sending data

### Terra API

1. Send dev-id and x-api-key headers on every Unified API and Terra AI call. A missing header returns 401 problem+json
2. Keep each request window to 1,825 days or less and under 6,000 requested days per user an hour. On 429 with rule r2, wait Retry-After seconds
3. Pass either fields or select to Terra AI tools, never both and never neither, or the call fails with a validation error
4. Expect data by webhook after a user connects through the widget session. REST reads are for backfills and on-demand queries
5. Use the Read only access level for the admin MCP server unless a change is needed. The MCP level can read API keys
