Sell expertise, not just hours.
Consultancies, law firms and accountancies run on research tools and data APIs that bill every month. APIPay covers those recurring costs, speeds up the work with one AI key and lets you productize your know-how as an API.
Estimates and recommendations, never guarantees · You stay in control
Built for Professional Services teams
What's holding Professional Services back.
The problems we hear most — and exactly what APIPay is built to fix.
Non-billable research time
Background research, first drafts and document review consume hours that rarely make it onto an invoice.
Per-matter data costs
Company data, filings and research APIs are priced per lookup, so every new engagement adds to overhead.
Expertise locked in people
Your frameworks and models only earn when a partner is in the room — there's no product clients can subscribe to.
The APIPay stack, tuned for Professional Services.
Three products for the APIs you pay for, the APIs you need and the APIs you sell — plus AI that works across all of them.

Professional Services, answered.
Still curious? Our team answers every message personally.
Is client information safe when we use AI Studio?
Access is deny-by-default, keys are managed centrally and secrets never reach the browser. You decide what information your workflows send, and we recommend keeping professionals in the review loop.
What kinds of expertise can become an API?
Anything with a repeatable input and output: scoring models, calculators, checklists, benchmarks or structured reports. API-Pay handles keys, plans and billing around it.
Does AI replace professional judgment?
No. AI outputs are estimates and recommendations. They speed up the work; your professionals remain responsible for the advice.
