Use cases
One API, imported once. Used where people already work.
Three ways teams put api0 to work, and one product running on it today. Every action runs as the person asking, with their own permissions.
Field service
Technicians run their jobs from WhatsApp
On site, the field-service app is slow on a phone. Reports get typed in the evening, from memory, and dispatch spends the day calling for status.
What gets set up
- Your field-service API: schedule, work orders, parts stock
- Each technician links their account once
- A WhatsApp Business number connected to api0
Channels: WhatsApp, Telegram, Teams
- TechnicianWhat's my day?
- Assistant3 visits. 1) 08:30 Lausanne, boiler X200, access code on file…
- TechnicianDone at Lausanne, replaced the filter, 2 FX-200 parts. Close it.
- AssistantClose job 1182 with that report and 2 × FX-200? (yes/no)
Software vendors
Your product in your customers' Teams
Customers ask for "AI in your product". Building an assistant and a Teams bot takes a team and months, and it must respect each user's rights.
What gets set up
- Your public API, imported from its OpenAPI spec
- One api0 tenant per customer: tools, users, credits, log
- A Teams app package generated by api0
Channels: Teams, Claude, WhatsApp, Telegram
- Customer userWhat are my urgent open tickets?
- Assistant4 urgent tickets. #2291 Export failing, open for 2 days…
- Customer userAssign #2291 to Paul and add a note: chasing the supplier.
- AssistantDone. Assigned to Paul, internal note added.
Internal tools
Internal systems in Claude Enterprise, securely
Claude doesn't know your ERP, CRM or HR tools, so people copy and paste. Security wants per-person rights, no secrets in the AI and an audit log.
What gets set up
- Your internal APIs as tools, reads first
- Sign-in through Entra ID or your OIDC provider
- Per-person credentials, so each system applies its own rights
Channels: Claude, Teams
- EmployeeHow many days off do I have left? Book me the 22nd to the 26th.
- Assistant12 days left. Request 5 days, 22–26 Dec, and send it to Claire? (yes/no)
- ManagerWho's off next week on my team?
- AssistantTwo people: Paul (Mon–Wed), Inès (Fri).
Running on api0 today
A CV-building SaaS
A SaaS that builds CVs imported its API into api0: 17 endpoints. Its users read their profiles, generate PDF CVs, translate them, tailor them to a job and write cover letters, from Claude and from messaging apps. Each call reaches the application with a Google identity token, so the application keeps no api0 secret.
- 17 endpoints, imported once
- Claude plus messaging channels
- No secret stored by the application
