## Which one, for what

### Capsule CRM (C)

Good for: Small teams already on Capsule who want an agent to read and write contacts, opportunities, projects and tasks over REST with a read-only scope available.

Ahead on:
- Reliability, 83 against 72

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

Watch for: No OpenAPI file, llms.txt or official SDK was found

### Zoho CRM (BB)

Good for: Teams already on Zoho who want an agent to read and write leads, contacts, deals and activities with narrow scopes, and small teams that want a free edition with API access.

Ahead on:
- Schema & documentation, 81 against 48
- Agent ergonomics, 81 against 59
- Security & auth, 67 against 46
- Payments & pricing, 40 against 30
- Maintenance & community, 77 against 38

Also in its favour:
- Agent-ready, a grade of BB or better

Watch for: The documented refresh and revoke calls put the refresh token and client secret in the URL query string

## Verdicts

**Capsule CRM.** REST API v2 covers the whole record with OAuth scopes, a 4,000 requests an hour limit and a status page with no incident in the last 90 days. There is no OpenAPI file, llms.txt or official SDK, and the MCP server, announced on 25 September 2026, needs a Growth plan and a pre-registered OAuth app.

**Zoho CRM.** A public OpenAPI 3.1 description of 644 operations and OAuth scopes down to one module and one operation suit agent use, and the Free edition includes 5,000 API credits a day. The documented token refresh puts the client secret in the URL, and no SLA, deprecation policy or dated API changelog was found.

## Before you call either

### Capsule CRM

1. Send `Authorization: Bearer <token>` to `https://api.capsulecrm.com/api/v2`. Projects use the old name in paths, `/kases`
2. Follow the `Link` header for the next page. `perPage` goes up to 100 and the default is 50
3. On 429, wait until the epoch time in `X-RateLimit-Reset`. The docs suggest one second between calls
4. Ask for the `read` scope when the task only reads. A write with a read-only token answers 403 with `insufficient_scope`
5. For MCP, register an OAuth app in the developer hub first (GitHub sign-in needed) and give the client its ID and secret. Personal API tokens are refused

### Zoho CRM

1. Use the `api_domain` returned with the token, since each data centre has its own host (zohoapis.com, zohoapis.eu, zohoapis.in and others)
2. Send `Authorization: Zoho-oauthtoken <token>` and refresh hourly. Put refresh parameters in the POST body, not the URL
3. Pass `fields` on every list call. Page with `page` up to 2,000 records, then `page_token` up to 100,000
4. Create through `/{module}/upsert` so a retry updates instead of duplicating
5. Budget credits. Convert Lead costs 5, Send Mail 20, a bulk read 50, and calls through the MCP servers draw on the same allowance
