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
