Solutions / General Services / API Integrations

Custom API Integration Services

Eliminate data silos, automate cross-platform workflows, and connect legacy software to modern databases and leading AI models like Claude, Gemini, ChatGPT, and Grok with secure, enterprise-grade API architectures engineered for high-volume operations.

Core capabilities & system bridging

Bridging the gaps between complex software ecosystems.

Off-the-shelf software often traps critical business data in closed silos. Practice management platforms like Clio or MyCase, proprietary accounting databases, and modern CRM systems rarely speak to each other seamlessly out of the box. We engineer bespoke API solutions and custom middleware engines that bridge these technical gaps, enabling data to flow securely between your core systems.

ReferenceWhat we build, by endpoint

CONNECT/systems/{clio|salesforce|quickbooks}

Practice management & enterprise system connectivity

  • Connect platforms like Clio, MyCase, Salesforce, or QuickBooks directly to your firm's internal databases and web applications.
  • Automatically trigger downstream tasks, such as generating engagement letters, creating client portals, or initiating billing sequences, the moment a matter or record updates in your primary software.
REST · GraphQL/v1/* · /graphql

Full-lifecycle custom API development

  • Specialized custom API development designed to expose clean, secure, and well-documented endpoints for internal applications or external client-facing tools.
  • Build high-throughput REST and GraphQL architectures equipped with robust authentication, rate limiting, and real-time Webhook event listeners.
TRANSFORM/pipelines/normalize

Unstructured data transformation & middleware pipelines

  • When off-the-shelf connectors fail to handle your proprietary business rules, we build custom API middleware that cleans, normalizes, and enriches data in transit between platforms.
  • Ensure complex financial calculations, custom legal fields, and document attachments transfer accurately between systems without manual intervention.
RAG/ai/search · /ai/draft · /ai/extract

Private RAG & LLM system integrations

  • Connect private AI pipelines and leading models such as Claude, Gemini, ChatGPT, and Grok directly to your core operational tools via secure API endpoints.
  • Allow team members to trigger RAG document searches, automated drafting, and AI entity extraction directly from within the software interfaces they already use every day.

AI model integrations

Connect the systems you already run to Claude, Gemini, ChatGPT, and Grok.

Frontier AI models are only as useful as the data they can reach. We build custom API integrations that securely connect your existing systems, from document repositories and case management platforms to student information systems, CRMs, and accounting ledgers, to the models your team wants to use: Anthropic’s Claude, Google’s Gemini, OpenAI’s ChatGPT models, xAI’s Grok, and open-weight models such as Llama and Mistral.

Model-agnostic by design

We route each task to the model that handles it best, whether that is Claude, Gemini, ChatGPT, or Grok, and you can switch providers as the market moves without rebuilding a single integration.

Your permissions travel with your data

Integrations respect the access rules of each source system, so a model only ever sees the case files, documents, or student records the requesting user is allowed to see.

Enterprise APIs, not consumer chat apps

We connect through each provider’s enterprise API, with zero-data-retention options where available, sensitive fields redacted before they leave your environment, and every request logged.

Bespoke vs. subscription

Stop paying per connection to move your own data.

Integration platforms and connector marketplaces charge per user, per connector, and per task run, so the cost climbs every time a workflow succeeds. Custom API integrations are built once around your systems, with no metered task fees and no middleman between your software.

  • 01

    No per-task or per-connector fees

    Our pricing is market competitive, and we never charge per connector, per user, or per API call. Your integrations can process more volume without a bigger bill, so custom wins in the long run.

  • 02

    Exactly the data flows you need

    A User Experience Designer is assigned to every project to map how information should move between your systems and the people who use it, including the dashboards and alerts around it.

  • 03

    You own the integration layer

    The code, mappings, and credentials live in your environment. No third-party platform sits between your systems or can change its pricing on you.

  • 04

    Support when an API changes

    We stay on after launch to handle support issues, update integrations when vendors change their APIs, add new connections, and respond to emergencies quickly.

  • 05

    Branded as your firm

    Any portals, dashboards, or notifications built on top of your integrations carry your firm’s brand, not a connector vendor’s.
