  title: Everhour Clients Projects API
  description: The Everhour API is a RESTful interface providing programmatic access to time tracking, timesheets, timers, projects, tasks, clients, invoices, expenses, resource scheduling, time off, and reporting data in Everhour. The API accepts and returns JSON (UTF-8 only). All requests are authenticated with an X-Api-Key header carrying an API key found at the bottom of your Everhour profile page. An optional X-Accept-Version header pins a specific API version (the most recent, 1.2, is used by default). The API is labeled BETA by Everhour, meaning some calls can be slightly adjusted; breaking changes are pushed in separate API versions. Time values are in seconds and money amounts are in cents throughout.

Where this information came from

This is an independent, third-party profile of Everhour Projects API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
