Verdicts

Apideck Accounting API + MCP

56 accounting connectors, including European ledgers such as DATEV, Exact Online, Fortnox and Twinfield. No published rate limits of Apideck's own, only connector limits mirrored in headers.

Zoho Books

The public OpenAPI files cover 885 operations with OAuth scopes per module and operation, and the Free plan allows 1,000 API requests a day. No report endpoint, official SDK, SLA or dated API changelog was found, and the documented token calls put the client secret in the URL.

Before you call either

Apideck Accounting API + MCP

  1. Stay in dynamic mode and search for tools. Static mode loads all 362 schemas
  2. Start the MCP with --lock-identity (or ?lock_identity=true) when one agent serves one customer
  3. Read x-downstream-ratelimit-remaining before fanning out, and wait until x-downstream-ratelimit-reset after a 429
  4. List before you retry a create that timed out. Writes aren't idempotent and there's no idempotency key
  5. Pass fields= on list calls to cut the response to the columns you need

Zoho Books

  1. Send organization_id as a query parameter on every call. Read it from GET /organizations first
  2. 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)
  3. Send Authorization: Zoho-oauthtoken <token> and refresh hourly. Each user keeps at most 20 refresh tokens and the oldest is deleted
  4. 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
  5. 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
