Plutio ships a self-serve REST API (v1.11) documented at docs.plutio.com: OAuth 2.0 client credentials from workspace settings, Mongo-style query filtering, and 1,000 requests per hour per key. Coverage spans projects, tasks, invoices, proposals, and contracts. No webhooks, so integrators poll.

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
