Customer-level API monitoring

See which customers are affected by every API issue.

Apirelio connects errors, latency, releases and API versions to the customer accounts behind each request, so engineering and customer teams can respond with context.

Customer-aware observability

Turn API telemetry into customer decisions.

Global averages tell you that something broke. Customer-level monitoring tells you who is experiencing it, how serious it is and where your team should act first.

01

Identify affected customers

Move from an error-rate graph to the exact accounts and integrations experiencing failed or slow API requests.

02

Prioritize by business impact

Separate an isolated retry from an incident affecting high-activity production customers.

03

Explain customer health

Combine reliability, latency, activity and adoption into transparent health signals your whole team can understand.

04

Compare releases

See which endpoints and customer accounts regressed after a deployment instead of relying on a global average.

05

Track API versions

Find every customer still sending traffic to a legacy API version before you plan its retirement.

06

Protect sensitive data

Capture operational metadata and customer identifiers without storing request bodies, response bodies or credentials.

Setup

From requests to customer impact.

Keep your current logging and tracing stack. Add the customer context that generic infrastructure monitoring cannot provide.

  1. 1

    Install a framework SDK

    Add Apirelio to Laravel, Symfony, Nette, Express, Fastify, NestJS, Nuxt, FastAPI or Django.

  2. 2

    Resolve the customer

    Map each authenticated request to the account and consuming application already known by your API.

  3. 3

    Investigate customer impact

    Use customer health, incident impact and release comparisons to decide what deserves attention first.

Questions

Frequently asked questions.

What is customer-level API monitoring?+

Customer-level API monitoring connects operational signals such as errors, latency, endpoints and releases to the B2B customers and integrations affected by them. It adds business context to traditional infrastructure and application monitoring.

Does Apirelio capture API payloads?+

No. Apirelio is designed around bounded operational metadata. Request bodies, response bodies, credentials, cookies and query strings are not captured.

Does this replace logs, traces or APM?+

No. Apirelio complements your existing observability stack. Logs and traces help engineers debug code; Apirelio helps teams understand which customers are affected and how urgently they should respond.

Which frameworks are supported?+

Apirelio provides integrations for Laravel, Symfony, Nette, Express, Fastify, NestJS, Nuxt, FastAPI, Django/DRF, Spring Boot and ASP.NET Core, covering PHP, TypeScript, Python, Java and .NET applications.
