Everhour Time Tracking API
✓ Official Vendor SpecProductivityTask ManagementapiKey40 EndpointsREST
For Agents
Manage Everhour clients, invoices, expenses, projects, tasks, and time records, and post or correct time entries on behalf of users.
Use for: List all Everhour clients, Create a new client called 'Acme Co', I want to log 2 hours of time against task 'task_123', Pull the invoice for client 'cl_456'
Not supported: Does not handle payroll, payment collection, or document signing — use for Everhour time tracking, project budgeting, and invoicing only.
The Everhour API is the programmatic surface for the Everhour time tracking and project budgeting platform. Forty operations across 24 paths cover clients, invoices, expenses, projects, tasks, time records, timers, timecards, timesheets, users, and resource planning. Authentication is via API key, and the API is well suited to syncing project time and budget data into accounting tools, BI dashboards, and AI agents that answer 'how many hours have we billed this client this month?'
Install Jentic One Beta
Connect the Everhour Time Tracking API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Everhour Time Tracking API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
Capabilities
What an agent can do with Everhour Time Tracking API.
Manage clients and per-client budgets via the /clients endpoints
Create, send, and update invoices including expense line items
Track expenses by project and reconcile them against time records
Manage projects and the tasks within them, including task search
Post time records and adjust existing entries
Read timecards, timesheets, and resource planning data for capacity reporting
Use Cases
Patterns agents use Everhour Time Tracking API for, with concrete tasks.
★ Time-to-Invoice Sync
Mirror Everhour time records and expenses into the accounting system so monthly invoicing is driven by actual tracked hours rather than manual exports. The /invoices, /expenses, and /time endpoints provide the structured data, and the per-client invoice endpoints let automation create, update, and finalise invoices. A working sync takes 1-2 days and saves finance teams hours per month.
For each client, pull /clients/{client_id}/invoices for the current period, plus matching /expenses, and post a draft invoice into the connected accounting tool
Project Budget Monitoring
Run a daily check that compares logged time against project budgets so project managers are warned before a project goes over. The /projects and /clients/{client_id}/budget endpoints expose the budget structure, and the /time and /tasks endpoints provide the actuals. Reports are produced in seconds per project.
For every active project, sum tracked /time hours and post a Slack alert if the project is at or above 80 percent of its budget
Capacity and Resource Planning
Power a capacity dashboard by combining timecards, timesheets, and resource planning data so leaders can see who is over-committed and where there is slack. The Everhour API exposes all three resources, and the data refreshes in seconds. This replaces manual spreadsheet planning.
Pull this week's timesheets and resource plans and post the names of the three people most over their target utilisation to the leadership channel
AI Agent Integration via Jentic
Connect Everhour to an AI assistant through Jentic so team members can post time records, check budgets, or run reports in chat. Jentic search resolves natural-language intents to the right Everhour operation and the vault holds the API key. Setup takes minutes once Everhour is connected.
Search Jentic for 'log everhour time entry', load the POST /time operation, and post '2 hours on task_123 today' captured from chat

Why Jentic?
Three things that make agents converge on Jentic-routed access.
Credential isolation
The Everhour API key is stored in the Jentic vault. Agents receive scoped execution tokens at runtime, so the raw key never enters the model context or chat history.
Intent-based discovery
Agents search Jentic by intent (e.g., 'log everhour time entry') and Jentic returns the matching operation with its schema, so the agent sends only the relevant fields.
Time to first call
Direct integration: 1-2 days for sync, retries, and invoice flows. Through Jentic: under 30 minutes from sign-up to first executed time entry.

FAQs
Specific to using Everhour Time Tracking API through Jentic.
What authentication does the Everhour API use?
The Everhour API uses an API key (apiKeyAuth scheme). Through Jentic, the key is stored in the encrypted vault and injected at execution time, so it never appears in the agent's prompt or in logs.
Can I post time records through the Everhour API?
Yes. POST /time creates a new time record, PUT /time/{time_id} updates an existing one, and DELETE /time/{time_id} removes it. This is the right surface for chat-based time logging or downstream sync from another tool.
What are the rate limits for the Everhour API?
The OpenAPI spec does not declare explicit rate limits. Treat the API as standard for SaaS and back off on HTTP 429; consult Everhour developer documentation for current published limits before bulk syncs.
How do I create an invoice through Jentic?
Search Jentic for 'everhour create invoice', load the POST /clients/{client_id}/invoices operation, and execute it with the line items. Install with pip install jentic and use the async search, load, execute pattern.
Does the Everhour API support project budgets?
Yes. PUT /clients/{client_id}/budget sets a client-level budget and DELETE /clients/{client_id}/budget removes it. Combine with /projects and /time to monitor burn rate over the budget.
Can I search tasks across all projects?
Yes. GET /tasks/search returns tasks matching a query string, which is faster than listing every project's tasks individually when looking for a specific work item.
