Production-grade REST and GraphQL APIs, secured and integrated.
We build the APIs your products and partners run on — clean REST and typed GraphQL, versioned so they don't break callers, secured at the gateway, and documented. All in your own cloud, production in 4–8 weeks.
Secured at the gateway · versioned, documented
The real problem
Why so many APIs become the thing nobody wants to touch.
An endpoint that returns JSON in a demo is the easy ten percent. The other ninety — versioning so a change doesn't break every app in the field, validation, auth and rate limiting, and docs the next team can integrate against — gets skipped under deadline.
So the API works until it's load-bearing, then turns into a fragile dependency every change has to tiptoe around. That fragility is expensive — 99% of organizations hit an API security issue last year, and 55% delayed shipping an application over it.
Where it earns its keep
Where API development earns its keep — and what each use case delivers.
"API development" is a set of specific jobs, each tied to a concrete outcome.
Public / partner APIs
Expose your platform to external developers and partners through a stable, versioned contract.
New distribution and revenue without bespoke integration work each time.
Third-party & SaaS integration
Connect your systems to the payment, CRM, accounting, and logistics platforms you depend on.
Data flows automatically where staff used to copy it by hand.
Mobile & frontend backends (BFF)
Give web and mobile clients a typed API — often GraphQL — that returns exactly what each screen needs.
Faster client teams and lighter, quicker apps.
Legacy system wrapping
Put a clean, modern API in front of an aging system you can't replace yet, so new products build against the contract, not the mainframe.
Modernize at the edges without a risky rip-and-replace.
Real-time & event-driven endpoints
Build low-latency WebSocket and event APIs for live data — status updates, notifications, streaming.
Live experiences without clients hammering the server to poll.
Internal service APIs
Define the contracts your own services talk over, with consistent auth, error shapes, and versioning.
Teams ship in parallel against stable interfaces instead of blocking on each other.
95% of API attacks come from authenticated sources. So a valid token isn't trust. We design authorization per request and the OWASP API Top 10 from the first endpoint — security as a property of the platform, not a patch.

What disciplined API work does to delivery — the measured impact.
Independent industry findings on API practice, cited as third-party evidence — not Silicon Prime's own client results.
Ship an API within a week. Up from 47% the year before, with 74% of organizations now API-first.
Delayed an application launch. Of organizations held a deployment because of API security concerns.
Of API attacks were authenticated. And 80% aligned with the OWASP API Security Top 10 — why authorization is checked per request.
What's included
What our API development services cover.
The difference between a production API and an endpoint that becomes a liability.
REST API design & development
Clean, resource-oriented REST APIs — consistent naming, predictable errors, pagination, and an OpenAPI spec that doubles as docs, mocks, and client SDKs.
GraphQL API development
Typed schemas that let many clients ask for exactly what they need in one request — with the resolver and performance work (depth limits, batching, N+1 prevention) that keeps it fast.
API integration services
Payment, CRM, accounting, and partner integrations, plus wrapping legacy systems behind a modern contract — so products build against a clean API, not brittle point-to-point links.
API gateways & security
A gateway centralizing auth, authorization, and rate limiting — OAuth 2.0 / JWT / API-key auth, request validation, and the OWASP API Top 10 designed against from the start.
Versioning, docs & developer experience
A versioning strategy that lets the API evolve without breaking callers, plus published docs, examples, and a sandbox so teams and partners integrate without a meeting.
Real-time & WebSocket APIs
Low-latency, event-driven endpoints (WebSocket, server-sent events) for live status, notifications, and streaming — built with the same auth and monitoring as the rest of the surface.
API maintenance & optimization
Take over an existing API: add the missing tests and docs, close the security gaps, fix the latency and reliability problems, and harden it for the load it's actually carrying.

How it runs
How an API development engagement runs.
The same delivery model behind all our software work, tuned for APIs — one accountable lead, fixed scope, no handoffs.
STEP 01
Design the contract
Model the resources or schema, auth model, versioning, and error shapes, and write the OpenAPI / GraphQL spec first.
Output: an agreed API contract callers can build against
STEP 02
Build
Implement the API in your own cloud tenant in Node.js and TypeScript, with validation, auth, and contract tests from the first endpoint.
Output: a working, tested API behind your access controls
STEP 03
Integrate
Wire it to your systems of record and third-party platforms through governed, permissioned connections, and stand up the gateway.
Output: an API connected to the systems it serves
STEP 04
Harden & hand over
Load-test, close OWASP-class gaps, instrument monitoring and rate limiting, publish the docs and sandbox, and train your team.
Output: a production API & a team that owns it
Track record
APIs that have already carried real money and real load.
There's no substitute for having built the transaction infrastructure a business runs on. APIs are the backbone of every system we build, and they have to stay reliable while everything around them changes.
A Stanford-rooted Responsible AI lab, founded 2011, run by founder Kelvin Tran — 20+ years of production engineering, personally accountable for every engagement.
Payment & transaction APIs · acquired 2017
YardClub — for the contractor-equipment marketplace we built the full platform end to end, including the listings, payments, and transaction APIs that processed $120M+ before Caterpillar acquired it. API work where a bug isn't cosmetic — it's a mishandled payment.
Reliable under change · 200+ locations · 4 yrs
BJ's Restaurants — the production discipline that holds a 200+ location chain at twice-a-week releases with zero critical defects across four years is what keeps an API stable while everything calling it keeps moving: contract tests before a change ships, staged rollout, monitoring after.
Why build your APIs with us.
We've built transaction infrastructure at scale. Payments and marketplace APIs that moved $120M+ (YardClub, acquired by Caterpillar) — not a first attempt on your dime.
Reliability is the product. The discipline that ships a 200+ location business twice a week with zero critical defects is the discipline behind an API you can put load on.
Security designed in, not patched on. Authorization per request and the OWASP API Top 10 designed against from the first endpoint — because 95% of API attacks come from authenticated sources.
Founder-led, built to transfer. One accountable lead from contract to handover; the schema, tests, gateway config, docs, and code are assigned to you, with your team trained to run it.
