Discovery + fixed milestones
Best when scope is clear. We run a short discovery, then deliver fixed-price milestones with demos, acceptance criteria, and a written handoff.
API Development
Design and ship production APIs — authentication, versioning, docs, and integrations your teams and partners can rely on.
What we deliver
API Development for growing businesses
API development for secure, well-documented REST and GraphQL interfaces that connect products, partners, and internal systems.
- REST and GraphQL API design and implementation
- Auth, rate limits, webhooks, and versioning
- Partner and third-party integrations
- OpenAPI docs, SDKs, and developer portals
Timeline: Typical production API MVP: 4–10 weeks after contract design.
In depth
How AVYRION delivers API Development
Who this is for
Teams that need reliable REST or GraphQL APIs for products, partners, and internal systems — with auth, versioning, docs, and observability that engineers trust.
AVYRION designs and ships API-first backends so integrations stop being the bottleneck.
Problems we solve
Undocumented endpoints, brittle partner integrations, and APIs that fail silently under load or abuse.
We start with contracts and SLAs, implement with tests, harden auth and validation, then publish docs and keys with monitoring.
What you get
REST and GraphQL design and implementation, webhooks, rate limits, OpenAPI docs, and partner-ready integration patterns.
You get APIs that are operable: logs, metrics, and a clear ownership model for change.
How delivery works
Contract → build → secure → publish. Common stacks include Node.js and Go with OpenAPI as the source of truth.
We integrate with your CI so breaking changes are caught before partners feel them.
Why teams choose AVYRION
Our team builds APIs as durable contracts — versioning, auth, observability, and docs — so integrations stay maintainable as your product grows.
API engagements often start as a fixed-scope contract design and build, then continue as a retainer once partners are live and integration volume grows. Share your endpoints and consumers on the contact form and we will propose milestones.
How we engage
Engagement models that match how you buy
Dedicated product squad
Best for evolving roadmaps. A tech lead plus engineers work as an embedded team with sprint cadence, shared backlog, and transparent velocity.
Retainer & care plans
Best after launch. Keep a reserved capacity for features, performance, security patches, and dependency updates so the product does not stall.
How we work
A clear path from idea to launch
Contract
Define resources, auth, and SLAs with stakeholders.
Build
Implement endpoints with tests and observability.
Secure
Harden auth, validation, and abuse controls.
Publish
Ship docs, keys, and monitoring for consumers.
FAQ
Questions about API Development
REST or GraphQL?
We choose based on client needs, caching, and team skills. Many products use REST for public partners and GraphQL for rich product UIs. Both can coexist behind the same auth and rate-limiting layer if your roadmap needs it.
Do you provide SDKs and developer portals?
We can ship OpenAPI-based docs, example clients, and portal basics when partner onboarding is part of the success metric. We also set up versioning and deprecation policies so partner integrations don't break silently.
How do you handle authentication?
OAuth2/OIDC, API keys, or mTLS patterns depending on audience — always with least privilege and rotation guidance. We document token lifetimes and scopes clearly so client teams don't have to reverse-engineer your auth flow.
Can you integrate third-party APIs for us?
Yes. We build resilient adapters with retries, idempotency, and clear failure modes for sales and support. We also add monitoring so a partner outage shows up in your dashboards before a customer reports it.
