Projects use the old name in paths, `/kases`\n2. Follow the `Link` header for the next page. `perPage` goes up to 100 and the default is 50\n3. On 429, wait until the epoch time in `X-RateLimit-Reset`. The docs suggest one second between calls\n4. Ask for the `read` scope when the task only reads. A write with a read-only token answers 403 with `insufficient_scope`\n5. 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\n\n### folk API + MCP\n\n1. Send `X-API-Version: 2025-06-09` on every REST call\n2. Set an `Idempotency-Key` on creates, and treat a 409 `IDEMPOTENCY_REQUEST_IN_PROGRESS` as wait and retry\n3. On a 429, wait until `details.retryAfter`, and remember all your keys share one 600-a-minute budget\n4. Move off the reminder endpoints to tasks before their removal on 2027-02-13\n5. Expect some interaction content to be hidden by the workspace's privacy rules\n\n## Questions\n\n### Which is better for AI agents, Capsule CRM or folk API + MCP?\n\nfolk API + MCP scores 60.8 (C) on agent readiness against Capsule CRM's 55.7 (C), and leads in 4 of 7 scored categories.
