        What we build
        
Three product lines. One standard: production-grade.

        
Every Fluxa API is scoped to your architecture during consultation, then delivered with documentation, SDKs, and a dedicated integration engineer.

      

      

        

          

          
Cloud Provisioning API

          
Programmatic control over compute, storage, and managed environments — multi-region, idempotent, and policy-aware.

          See the Cloud API →
        

        

          

          
Secure Network & VPN API

          
Provision tunnels, rotate keys, and manage peer access across fleets — WireGuard-based, audited, zero-trust by default.

          See the Network API →
        

        

          

          
Update Delivery API

          
Signed, staged, and resumable software updates for any fleet — phased rollouts, instant rollback, delta patching.

          See the Update API →
        

      

    

  


  

    

      

        The Fluxa model
        
We don't sell off the shelf.
We sell what fits.

        
Every engagement starts with a consultation, because infrastructure APIs that aren't shaped to your stack become liabilities.

      

      

        
Scope
A working session with our architects to map your environment, constraints, and the exact API surface you need.

        
Architect
We design the integration — endpoints, auth model, failure modes, and SLAs — and hand you a written technical proposal.

        
Integrate
Your dedicated Fluxa engineer ships alongside your team until the API is live, monitored, and load-tested in production.

      

    

  


  

    

      

        
Built to be measured.
Every contract ships with hard numbers — and a dashboard that holds us to them.

        Solutions
        
Specialized APIs, not generic endpoints.

        
Each product line below is configured per engagement. The samples show real request shapes from production integrations.

      

      

        
        
        
      


      

        

          
Cloud Provisioning API

          
Stand up and tear down environments across providers with a single, policy-aware interface. Declarative requests, idempotent by design, with org-level guardrails enforced at the API layer — not in code review.

Secure Network & VPN API

          
Programmatic WireGuard-based networking for fleets, sites, and remote teams. Create tunnels, rotate keys on schedule, and revoke peers instantly — every action logged to an immutable audit trail.

Update Delivery API

          
Ship signed software updates to any fleet — servers, desktops, embedded devices — with phased rollouts, health-gated promotion, and one-call rollback. Delta patching keeps payloads small and windows short.

Which one fits your stack?
Bring us the problem — scoping it is what the consultation is for.

        How we work
        
Consultation isn't a sales step.
It's the engineering.

        
Fluxa has no checkout page on purpose. Infrastructure APIs touch your most sensitive systems — the fit has to be designed, not downloaded.

      

      

        

          
01

          
Discovery call
A 45-minute session with a Fluxa architect — not a sales rep. We map your current stack, compliance constraints, and what "done" looks like for you.
~ week 1

        

        

          
02

          
Technical proposal
You receive a written design: API surface, auth model, data flows, failure modes, SLAs, and a fixed integration timeline. Review it with your team — no obligation.
~ week 2

        

        

          
03

          
Guided integration
A dedicated Fluxa engineer joins your channel. Sandbox keys on day one, production credentials when your tests pass ours.

Quarterly architecture reviews, proactive capacity planning, and a 24/7 on-call line staffed by engineers who know your deployment by name.

        What you get
        
Every engagement includes

      

      

        
A named engineer
One person owns your integration end to end. You'll know their name, their timezone, and their Slack handle.

        
SLAs in writing
Uptime, latency, and support-response commitments are contractual — with credits, not apologies, when we miss.

        
No version surprises
Breaking changes never ship to your endpoints without a migration plan we build together, on your schedule.

      

    

  


  

    

      

        
Start with the discovery call.
It's free, it's technical, and it usually saves teams a quarter of integration time.

        Security & compliance
        
Security is the product.

        
Our APIs sit inside your network and update paths. That position demands a higher bar — here's how we hold it.

      

      

        
Encryption everywhere

          
  • TLS 1.3 on every endpoint, no downgrade paths
  • WireGuard (ChaCha20-Poly1305) for all tunnels
  • Customer data encrypted at rest with per-tenant keys
  • Ed25519 signing on every update payload

        
Access & identity

          
  • Short-lived, scoped API tokens — no static master keys
  • mTLS available for service-to-service calls
  • SSO / SCIM for team access management
  • Per-endpoint role policies enforced server-side

        
Auditability

          
  • Immutable audit log on every state-changing call
  • Streaming export to your SIEM
  • Key rotation events independently logged
  • Quarterly third-party penetration tests

        
Resilience

          
  • Active-active across 3+ regions
  • Health-gated deployments with automatic rollback
  • Documented RTO / RPO per contract
  • Status page with real-time incident history

      

      

        
SOC 2 Type II

        
ISO 27001

        
GDPR-ready

        
HIPAA-eligible deployments

      

      
Compliance documentation and audit reports are shared under NDA during consultation.

    

  







  

    

    

      

        About Fluxa
        
Built by the people who used to get paged.

        
Fluxa was founded by infrastructure engineers who spent a decade integrating brittle third-party APIs into systems that couldn't afford downtime. We started the company to build the APIs we always wished existed — specialized, documented, and backed by humans who answer.

        
Today we serve platform teams across fintech, healthcare, telecom, and the public sector, with a deliberately small client list. Consultation-only isn't a constraint — it's how we keep every deployment one we'd stake our name on.

      

      

        
Specialized over general
We'd rather do three things at production grade than thirty at demo grade.

        
Engineers answer the phone
Support tickets route to people who can read your logs, not a tier-one script.

        
Boring on purpose
Predictable releases, stable contracts, no surprise deprecations. Excitement belongs in your product, not your infrastructure.

        
Few clients, deep work
We cap concurrent engagements so every client gets senior attention.

No obligation
The discovery call and written proposal are free. You decide with your team afterward.
