What changes when it is legal services

Versioning is a promise to the people building on you. We make the strategy explicit up front, so a future change is a planned migration rather than an outage.

In legal services, privilege and confidentiality mean data handling is scrutinised more than model performance. That single fact reshapes how api design & integration has to be built here, the guardrails, the approval points and the evidence trail are design inputs rather than things bolted on before go-live.

The workload we are most often asked to take on first is matter summarisation, usually integrated against matter management. Integration comes before intelligence. A model that cannot reach your systems of record is a demo with good manners.

Built by engineers who ship production systems, not by a practice that subcontracts the build. You own the code, the models where they are open-weight, and the documentation to run it without us.

API Design & Integration workloads in legal services

  • contract review and clause extraction
  • discovery document triage
  • precedent research
  • matter summarisation
  • billing narrative drafting

What is included

  • OpenAPI specification written before the implementation
  • Versioning strategy that does not break consumers
  • Authentication, scopes and rate limiting
  • Webhooks with retries and signature verification
  • Idempotency on every state-changing endpoint
  • Generated documentation and a sandbox

Questions from this sector

Does using AI risk privilege?

Not if the deployment keeps data inside your control, on-premise or a dedicated tenancy with no training on your content. That is the arrangement we build by default for legal work.

Can it be trusted on case law?

Only with retrieval grounding and citations to real sources. Unguarded models fabricate citations, which is precisely why we never ship legal work without source verification.

REST or GraphQL?

REST for partner-facing and public APIs where caching and simplicity matter; GraphQL where a first-party client needs flexible, varied queries. Most systems end up with both, used deliberately.

Do you document it?

Generated from the OpenAPI specification, with a working sandbox. Documentation written by hand and separately always drifts.

Can you integrate with legacy SOAP systems?

Yes, usually by wrapping them in a clean modern interface rather than exposing the legacy contract onward.

API Design & Integration for legal services, worth a conversation?

Tell us the workload and the regulation it sits under. We will tell you what is realistic.
