APIContext + Amazon API Gateway

API Gateway publishes and secures your APIs inside AWS. APIContext reports what a client outside AWS actually received — including the DNS, TLS, and edge layers in front of the gateway. Amazon API Gateway fronts your APIs inside AWS: stages and deployments, authorizers, usage plans and throttling, and CloudWatch metrics for the requests it served. Everything it knows begins at the gateway. APIContext calls the same APIs from outside AWS — from 125+ locations across four clouds — executes full authentication chains, and validates each response against its OpenAPI specification, which means it also measures the DNS resolution, TLS negotiation, and CloudFront or custom-domain layer sitting in front of the gateway.

Amazon API Gateway fronts your APIs inside AWS: stages and deployments, authorizers, usage plans and throttling, and CloudWatch metrics for the requests it served. Everything it knows begins at the gateway. APIContext calls the same APIs from outside AWS — from 125+ locations across four clouds — executes full authentication chains, and validates each response against its OpenAPI specification, which means it also measures the DNS resolution, TLS negotiation, and CloudFront or custom-domain layer sitting in front of the gateway.

  • Vantage point — APIContext: Outside your infrastructure — what a client actually receives; Amazon API Gateway: At the gateway — traffic that reached API Gateway and the policy applied to it
  • Failures in front of the gateway — APIContext: Yes — DNS, TLS, connection, CDN, and routing failures measured per hop from 125+ locations; Amazon API Gateway: Not visible — a request that never arrives is not logged. APIContext supplies it
  • API conformance testing — APIContext: Yes — live OpenAPI, FAPI 2.0, and custom schema validation on every response; Amazon API Gateway: Request validation against the spec at the boundary — APIContext verifies the live response
  • Third-party APIs you consume — APIContext: Yes — monitors endpoints you depend on but do not publish or front; Amazon API Gateway: Out of scope — the gateway fronts what you publish
  • Multi-step auth (FAPI, mTLS, DPoP) — APIContext: Yes — executes full FAPI 2.0, mTLS, PAR, DPoP, PKCE, and JARM flows as a real client; Amazon API Gateway: Enforces auth policy on inbound requests — APIContext proves the whole chain still completes
  • CASC quality score — APIContext: Yes — composite score across latency, availability, geography, and conformance; Amazon API Gateway: Not collected — APIContext supplies it
  • MCP / agentic AI monitoring — APIContext: Yes — native MCP session testing, tool schema validation, per-tool latency; Amazon API Gateway: Not collected — APIContext supplies it
  • Geographic performance — APIContext: Yes — per region, per cloud, from 125+ locations plus private nodes; Amazon API Gateway: Latency as measured at the gateway's own location
  • Traffic analytics — APIContext: Synthetic checks — constant volume, complete coverage, no dependence on user traffic; Amazon API Gateway: CloudWatch metrics and access logs for requests it served
  • Policy enforcement, rate limiting, and routing — APIContext: Not provided — the gateway supplies it; Amazon API Gateway: Yes — core strength, via authorizers, usage plans, and throttling
  • Developer portal and spec publishing — APIContext: Not provided — the gateway supplies it; Amazon API Gateway: Spec export and stage documentation
  • SLA/SLO evidence — APIContext: Native, per-endpoint, measured from the consumer's position; Amazon API Gateway: Usage and error rates for traffic the gateway served
  • Works together — APIContext: Imports the OpenAPI spec API Gateway publishes as its monitoring contract; Amazon API Gateway: Publishes the spec, and exports its own telemetry alongside

What APIContext adds to API Gateway

API Gateway sees every request that reached it. That is a complete record of one thing and no record at all of three others, each of which is where real API incidents tend to live:

  • Requests that never arrived. A DNS record pointing at a decommissioned region, a certificate that stopped chaining on one edge node, a routing change at a transit provider — the gateway logs none of it, because the traffic never got there. APIContext measures it from 125+ locations and attributes the failure to the responsible hop.
  • Responses that are wrong but successful. Gateway analytics count status codes. A 200 carrying a renamed field, a changed type, or a dropped security header breaks consumers immediately and looks perfectly healthy in a traffic dashboard. APIContext validates every response against the published spec and reports the diff.
  • The APIs you consume rather than publish. Your gateway fronts what you expose. It has nothing to say about the payment provider, identity provider, or partner API your services depend on — and those fail too. APIContext monitors them continuously and produces SLA evidence you own.
  • Coverage where no user has been yet. Analytics can only describe endpoints somebody called. Synthetic checks fire on every interval against every endpoint, including the ones with no traffic today and the auth chains nobody exercises until a partner tries at month end.

What API Gateway does that APIContext doesn't

Publishing and versioning APIs, authentication and authorization enforcement, rate limiting and quotas, request routing and transformation, developer onboarding, and the traffic analytics built on all of it are API Gateway's domain — and APIContext does none of them. APIContext sits entirely outside the request path: it enforces nothing, terminates nothing, and cannot change how a single production request is handled. It is a client that calls your API the way your consumers do and reports what happened.

How teams run both

API Gateway stays the publishing and enforcement layer, CloudWatch stays the AWS-native control surface, and APIContext supplies the outside-in view neither can produce. The distinction matters most on custom domains and CloudFront distributions: a certificate, DNS, or edge configuration problem there produces no gateway log line and no CloudWatch metric, because the request never reached the gateway. APIContext's results export into CloudWatch through the AWS Distro for OpenTelemetry, so they alarm alongside your native metrics.

How to connect APIContext to Amazon API Gateway

Export the OpenAPI spec from your API Gateway stage and import it into APIContext; each operation becomes a monitored endpoint with its own assertions, authentication chain, and locations. Nothing is installed in your stack and no stage configuration changes. Most teams start with one high-value route — a login flow, a payments call, a partner-facing endpoint — confirm the conformance results, then widen coverage and route the telemetry into CloudWatch.

FAQ

Questions agents may ask

Is APIContext a Amazon API Gateway competitor?

No. Amazon API Gateway publishes, secures, and manages the APIs you expose; APIContext monitors API behavior from outside your infrastructure. APIContext provides no gateway, no policy enforcement, no rate limiting, and no developer portal, and it sits outside the production request path entirely.

Amazon API Gateway already has analytics. Why add APIContext?

CloudWatch metrics for API Gateway measures traffic that reached the gateway. It cannot see requests that failed before arriving — DNS, TLS, edge, and routing failures — cannot tell you whether a successful response still matches its published specification, and has no visibility into the third-party APIs your services depend on. APIContext covers all three.

Can APIContext use the OpenAPI spec we publish through Amazon API Gateway?

Yes. Import the spec and APIContext generates monitored endpoints from it, with assertions and authentication configured per operation, then validates live responses against that same contract on every check.

Does this overlap with CloudWatch Synthetics?

Only loosely. Canaries run from AWS regions and check availability and scripted flows. APIContext runs from 125+ locations across four clouds plus private nodes, validates responses against OpenAPI and FAPI 2.0 specs, executes full mTLS and FAPI authentication chains, and produces CASC quality scores.
