AI-Powered · API Development REST & GraphQL / Built for production

AI-driven API development services — REST and GraphQL, built for production.

Enterprise API development services — REST and GraphQL APIs, third-party and legacy integration, gateways, and real-time endpoints. We build on Node.js and TypeScript, version and document every interface, and ship with authentication, rate limiting, and monitoring built in.

Backed by an AI-driven defect-reduction edge so your APIs hold up in production, not just in a demo — typed end to end, secured at the gateway, and operated long after launch.

 01 / What we build

The interfaces your
systems build on.

REST and GraphQL APIs, integrations, gateways, and real-time endpoints — designed around your resources and shipped as versioned, documented, production-grade services.

REST

REST APIs

Clean, versioned REST APIs designed around your resources — predictable, cacheable, and documented with OpenAPI so clients and partners can integrate without guesswork.

GraphQL

GraphQL APIs

Typed GraphQL schemas that give many clients exactly the data they need — no over-fetching, with the resolvers, batching, and depth controls a production graph requires.

Integration

API integration

Third-party, payment, CRM, and legacy integrations wrapped behind clean interfaces — with retries, idempotency, and error handling so the link stays reliable when upstreams misbehave.

Gateway

API gateways and security

Gateways that centralize authentication, authorization, and rate limiting — OAuth 2.0, JWT, and API keys, hardened against the OWASP API Security risks before traffic reaches your services.

Real-time

Real-time and WebSocket APIs

Low-latency, event-driven endpoints — WebSocket, server-sent events, and streaming — for live updates, notifications, and collaborative features that scale under real load.

Maintain

API maintenance

API optimization and maintenance on existing services — fixing reliability and latency, adding tests and documentation, tightening security, and managing versioning and deprecation without breaking your clients.

 02 / What's included

A production API,
not just an endpoint.

An API is easy to stand up and hard to operate. Every engagement includes the parts that keep it reliable, secure, and easy to consume long after launch.

  • API design — REST or GraphQL, decided on evidence from your use case
  • Authentication and authorization — OAuth 2.0, JWT, or API keys
  • Input validation, rate limiting, and throttling at the gateway
  • Third-party and legacy integration with retries and idempotency
  • Versioning and a deprecation path that never breaks live clients
  • OpenAPI or GraphQL schema docs and a self-serve developer portal
  • Automated tests, observability, audit logging, and monitoring
  • Documentation and handover so your team can own it
 03 / Integrations

Integrations across
every industry.

And many more — if it has an API, a webhook, or even a legacy SOAP endpoint, we've connected it. Don't see your platform? It's almost certainly one we can integrate.

APIs built the way
we ship everything.

We are an AI lab born out of Stanford, building Responsible AI for the enterprise since 2011. APIs are the backbone of every system we build, and we ship them on Node.js and TypeScript — the same backend stack behind our production work — so your interfaces are typed end to end, fast, and maintainable. The production rigor behind Aegis AI, our enterprise production suite, goes into every endpoint: it delivered twice-weekly releases with zero critical defects across a 200+ location enterprise for 12 months.

The result: APIs your partners and your own teams can build on with confidence — secure, versioned, documented, and operated, not abandoned at launch. See how we think about human-led AI, or talk to us about the interface you need to ship.

Interfaces your partners and your own teams can build on — proven in production, not just demoed.

APIs that hold up under real load — on a live production system.

APIs are the backbone of every system we build, and they have to stay reliable while everything else keeps moving. BJ's Restaurants, a 200+ location enterprise, runs a demanding production environment — and with Aegis AI the team sustained twice-weekly production releases with zero critical defects for the past year.

 05 / Frequently asked

API development,
answered.

The questions product and engineering leaders ask before committing to a new interface — or handing over an existing one.

API development services design, build, and operate the interfaces that let your applications, partners, and internal systems exchange data — REST and GraphQL APIs, third-party and legacy integrations, gateways, and real-time endpoints. We deliver these as versioned, documented, production-grade APIs with authentication, rate limiting, and monitoring built in, not just an endpoint that returns JSON.

It depends on your clients and data. REST is simple, cacheable, and a good fit for resource-oriented services and public APIs; GraphQL shines when many clients need different shapes of related data and you want to avoid over-fetching. We make the trade-off explicit with evidence from your use case, and we are equally comfortable shipping either — or both behind one gateway.

Yes. We integrate payment, CRM, messaging, and other third-party APIs, and we wrap legacy and SOAP systems behind clean, modern interfaces. We handle authentication, retries, idempotency, and error handling so the integration stays reliable even when the upstream service does not.

Every API ships with authentication and authorization — OAuth 2.0, JWT, or API keys — input validation, and rate limiting and throttling at the gateway. We follow the OWASP API Security guidance, add observability and audit logging, and make abuse and overload visible before they reach your core services.

Yes. We take over existing REST and GraphQL APIs to fix reliability and latency issues, add tests and documentation, tighten security, and manage versioning and deprecation. The same Aegis AI defect-reduction edge that delivered twice-weekly releases with zero critical defects over 12 months keeps changes safe.
