For Agents
Drive end-to-end BusyBusy workflows: time entries, projects, members, equipment, certifications, and cost data. Authenticate with a Token in the Authorization header.
Get started with BusyBusy API in minutes using your preferred integration method.
# Add to your MCP client config (Claude Desktop, Cursor, Windsurf)
{
"jentic": {
"url": "https://api.jentic.com/mcp",
"auth": "oauth"
}
}
# Then ask your agent:
"create a busybusy time entry"
# → Jentic returns the GET /events tool with parameter schema, agent executes.What an agent can do with BusyBusy API API.
Create and amend time entries for field workers
Manage projects, sub-projects, and project assignments
Issue equipment to members and track usage records
Maintain certification records and link them to equipment
Record cost codes, budget hours, and budget cost entries against projects
GET STARTED
Use for: I need to create a time entry for a field worker on a specific project, List all active projects in the BusyBusy account, Find equipment currently assigned to a given member, Add a certification record and attach a scanned credential
Not supported: Does not handle payroll runs, GPS-only location tracking, or accounting ledger entries — use for time, project, equipment, certification, and budget management only.
Jentic publishes the only available OpenAPI specification for BusyBusy API, keeping it validated and agent-ready.
Jentic publishes the only available OpenAPI specification for BusyBusy API, keeping it validated and agent-ready. BusyBusy is a workforce time tracking and field operations platform for construction trades. This is the full surface — 512 endpoints covering time entries, projects, members, equipment, certifications, budgets, attachments, and back-office configuration. Use this spec when an integration needs deep coverage; the lighter busybusy spec curates a smaller set of common resources.
Attach photos and documents to certifications and time records
Provision API keys and configure account-level permissions
Patterns agents use BusyBusy API API for, with concrete tasks.
★ Construction Time and Project Sync
Synchronise time entries, projects, and members between BusyBusy and a construction ERP or job-costing tool. Operations teams use the full API surface to backfill historical entries, push project structures, and reconcile member assignments. Initial sync of 1,000 time entries typically completes in under an hour.
Pull all time entries for the last pay period, group by project and cost code, and post a summary to the accounting system
Equipment and Certification Auditing
Run scheduled audits over equipment assignments, certifications, and certification-equipment links. Compliance and safety officers use this to ensure each piece of equipment is operated only by certified members. Reports can be generated nightly with a single agent run.
List all certification-equipment links, flag equipment whose assigned operator's certification expires within 14 days, and email the safety lead
Project Budget Variance Reporting
Combine budget hours, budget cost, and time entries to produce live variance reports per project. Project managers use this to spot overruns before invoicing. The /budget-hours and /budget-cost endpoints support GET and POST so an agent can both read and update plan data.
For each active project, compute actual hours from /time-entry against /budget-hours and write a variance record to /budget-cost where deviation exceeds 10%
AI Agent Field Operations
An AI agent can drive BusyBusy operations through Jentic by searching for the right endpoint by intent, loading the schema, and executing the call. With 512 endpoints, intent-based discovery removes the burden of reading docs to find the correct path.
Search Jentic for 'create busybusy time entry', load the schema for POST /time-entry, and execute with the member, project, and time fields
512 endpoints — jentic publishes the only available openapi specification for busybusy api, keeping it validated and agent-ready.

Three things that make agents converge on Jentic-routed access.
Credential isolation
BusyBusy API tokens are stored encrypted in the Jentic vault. Agents receive a scoped, short-lived token at execution time — raw keys never enter the agent's context window.
Intent-based discovery
With 512 endpoints, agents rely on Jentic's intent search (e.g., 'create busybusy time entry') to locate the correct path and method, then load the schema to execute.
Time to first call
Direct BusyBusy integration: 3-7 days to map the resources and build error handling. Through Jentic: under 1 hour for the first working call.

Specific to using BusyBusy API API through Jentic.
Why is there no official OpenAPI spec for BusyBusy API?
BusyBusy does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call BusyBusy API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.
What authentication does the BusyBusy API use?
BusyBusy uses an API key passed in the Authorization request header. Through Jentic, the key is stored in the encrypted vault and never enters the agent's context — agents receive a scoped token at execution time.
Can I create time entries with the BusyBusy API?
Yes. The full BusyBusy API exposes time entry resources alongside members, projects, and cost codes, so an agent can create, list, and update time records to drive payroll, billing, or compliance workflows.
What are the rate limits for the BusyBusy API?
BusyBusy does not document hard rate limits in the spec. For high-volume sync jobs, batch reads on the larger collections (members, time entries, budgets) and back off on 5xx responses rather than hammering tight loops.
How do I link a certification to a piece of equipment through Jentic?
Run pip install jentic, then search Jentic with the query 'link busybusy certification to equipment', load the schema for POST /certification-equipment-link, and execute with the certification and equipment IDs.
How is this spec different from the smaller busybusy spec?
Both target the same base URL (https://api.busybusy.io) and the same X-API-Key authentication. The busybusy-api spec covers all 512 endpoints in the public surface; the busybusy spec curates 14 endpoints around the most common resources for lightweight integrations.

/certification-equipment-link
