What Vaughn & Mercer Actually Delivers
A concrete overview of the platform's capabilities, architecture, and what you receive on day one.
Vaughn & Mercer is a managed API infrastructure platform delivered as a set of composable services: a high-throughput gateway, an SDK factory, an auth-and-policy engine, and a real-time observability suite. You connect your existing codebase via a CLI or GitHub Action, define your API surface in OpenAPI 3.1, and the platform handles routing, versioning, authentication scaffolding, and client SDK generation automatically. Typical onboarding for a single service takes between 45 minutes and two hours. You receive a dedicated subdomain, a private SDK registry, a monitoring workspace, and access to our support channel within the first 24 hours.
Platform Architecture at a Glance
Four discrete modules that compose cleanly and can be adopted incrementally.
Gateway Engine
A multi-tenant, edge-aware API gateway built on Envoy proxy. Handles TLS termination, request transformation, load balancing across upstream origins, and circuit-breaking. Configurable entirely through a declarative YAML file checked into your repo.
SDK Factory
Upload or point to your OpenAPI spec and receive versioned client libraries in TypeScript, Python, and Go within 60 seconds. Each library includes type stubs, retry logic, and inline documentation blocks. Published automatically to your organization's private registry.
Auth & Policy Engine
Centralised OAuth 2.0 flows, API key issuance, JWT validation, and per-route policy definitions in one panel. Supports per-consumer quotas, IP allowlisting, and audit logging exportable in JSON or CSV.
Observability Suite
Trace-level visibility across every hop in your request path. Real-time latency percentiles, error clustering, and anomaly flagging surface in the dashboard within 3 seconds of occurrence. Compatible with OpenTelemetry, Prometheus, and Datadog.
Platform Screens
Clean, sand-olive toned dashboards designed to show you signal, not noise.
“The Gateway Engine replaced an in-house Nginx setup we had been maintaining for over 18 months. Configuration that used to require a senior DevOps engineer to modify now lives in a single YAML file that any developer on our team can read and edit. We went from three deploy-related incidents per month down to zero in the first six weeks after migration.”

Common Technical Questions
Straight answers to the questions engineering leads ask before signing up.
Does the gateway support WebSocket and gRPC, or only REST?
The Vaughn & Mercer gateway natively proxies HTTP/1.1, HTTP/2, WebSocket upgrade connections, and gRPC streams. You configure protocol-specific settings in the same declarative YAML that governs your REST routes — no separate configuration file or plugin required.
Where are the infrastructure nodes located?
We operate primary nodes in Singapore, Frankfurt, and Northern Virginia, with read-replica cache nodes in Tokyo and Sydney. Requests are routed to the nearest healthy node automatically. Customers on the Enterprise tier can request private node placement in a specific cloud region.
How does versioning work when we break our API schema?
The SDK Factory diff-checks every new spec against the prior published version and flags breaking changes before it generates new SDKs. You choose whether to cut a new major version or patch in place. Old SDK versions remain available in the private registry until you explicitly deprecate them.
Can we bring our own domain and TLS certificate?
Yes. You can map any custom domain to your Vaughn & Mercer gateway endpoint and either supply your own certificate or let the platform auto-provision one via Let's Encrypt. Certificate renewal is handled automatically with no downtime.
