No report endpoint, official SDK, SLA or dated API changelog was found, and the documented token calls put the client secret in the URL.\n\n## Before you call either\n\n### Pennylane\n\n1. Call `GET https://app.pennylane.com/api/external/v2/me` first to confirm the token, user and company context\n2. Stay under 25 requests per 5 seconds per token and wait for the `retry-after` value on a 429\n3. Do not retry a create after a timeout without checking first. Only supplier invoice imports are deduplicated\n4. Send `filter` and `sort` again with every `cursor`. The cursor stores position only\n5. Send amounts as strings such as \"120.00\", and ask for `:readonly` scopes when the task only reads\n6. Use the MCP server for reads only. It cannot create, edit or delete, and firm connections need `company_id`\n\n### Zoho Books\n\n1. Send `organization_id` as a query parameter on every call. Read it from `GET /organizations` first\n2. Use the `api_domain` returned with the token, since each of the nine data centres has its own host (zohoapis.com, zohoapis.eu, zohoapis.in and others)\n3. Send `Authorization: Zoho-oauthtoken \u003ctoken\u003e` and refresh hourly. Each user keeps at most 20 refresh tokens and the oldest is deleted\n4. Stay under 100 requests a minute and the plan's daily cap. Codes 44, 45 and 1070 on a 429 mean minute, day and concurrency limits\n5. To repeat an update safely, send `X-Unique-Identifier-Key`, `X-Unique-Identifier-Value` and `X-Upsert` with a unique custom field. Creates have no idempotency key\n\n## Questions\n\n### Which is better for AI agents, Pennylane or Zoho Books?\n\nPennylane scores 66.3 (B) on agent readiness against Zoho Books's 61.1 (C), and leads in 5 of 7 scored categories. Zoho Books leads on payments \u0026 pricing.\n\n### Do Pennylane and Zoho Books need an API key?\n\nPennylane takes an API key or an OAuth sign-in. Zoho Books uses an OAuth sign-in.\n\n### Can an agent call Pennylane and Zoho Books without installing anything?\n\nYes. Pennylane has a hosted endpoint at https://app.pennylane.com/api/external/v2 and Zoho Books at https://www.zohoapis.com/books/v3.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/pennylane-vs-zoho-books.json, and with the fewest tokens: https://www.anchorterminal.com/compare/pennylane-vs-zoho-books.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"pennylane\", \"b\": \"zoho-books\"}`.
