bugsnag

Bugsnag is an application stability monitoring platform that helps software teams detect, diagnose, and fix errors in web, mobile, and back-end applications.

agent ready

Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.

Kin Score

API Evangelist profiles bugsnag the way a machine reads it — 94 machine-readable artifacts across 16 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.

Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — bugsnag scores 45.4/100 (developing), with a separate agent-readiness read of 54/100 (agent ready). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile bugsnag

Each block below is one kind of artifact we hold for bugsnag. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

APIs 16

Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Individual APIs this provider publishes, each with its own machine-readable definition.

bugsnag Builds API

Notify Bugsnag about application builds and deployments. Build notifications are used to track releases, identify regressions, and associate source control information with erro...

bugsnag Collaborators API

Manage collaborators within an organization or project. Collaborators are users who have access to view and manage Bugsnag data.

bugsnag Comments API

Manage comments on errors. Comments allow team members to discuss and annotate specific errors.

bugsnag CurrentUser API

Access information about the currently authenticated user.

bugsnag Errors API

Access and manage errors within projects. Errors represent groups of similar events that have been detected by Bugsnag.

bugsnag EventFields API

Access event field definitions for projects. Event fields describe the available data dimensions for filtering and searching events.

bugsnag Events API

Access individual error events. Events represent individual occurrences of an error within a project.

bugsnag Notifications API

Send error and exception notifications to Bugsnag. Each notification can contain one or more events representing individual error occurrences.

bugsnag Organizations API

Access and manage organizations. An organization is the top-level entity in Bugsnag that contains projects and collaborators.

bugsnag Pivots API

Access pivot data for errors. Pivots allow you to group and analyze error data by various dimensions such as browser, device, or location.

bugsnag Projects API

Access and manage projects within an organization. Projects represent individual applications being monitored by Bugsnag.

bugsnag Releases API

Access release information for projects. Releases represent deployed versions of your application and their associated error data.

bugsnag Sessions API

Report session data to Bugsnag for stability score calculations. Sessions represent periods of user activity and are used to compute crash-free session and user percentages.

bugsnag Stability API

Access stability metrics for projects. Stability data provides crash-free session and user percentages across releases.

bugsnag Traces API

Send OpenTelemetry trace data to Bugsnag for performance monitoring. Spans represent individual operations and are assembled into traces that visualize request flow and latency.

bugsnag Trends API

Access trend data for errors and projects. Trends provide time-series data showing how error rates and stability change over time.

Open Collections 5

Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.

Pricing Plans 1

Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.

Published pricing tiers and plan structures.

Rate Limits 1

Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.

Documented rate limits and quota policies.

FinOps 1

Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.

Event Specifications 1

Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

AsyncAPI definitions for this provider's event-driven and streaming APIs.

Bugsnag Webhook Events

Bugsnag webhooks deliver real-time notifications about error events to a configured callback URL via HTTP POST. The webhook integration sends JSON payloads containing informatio...

Semantic Vocabularies 1

JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.

JSON Schema 45

Standalone JSON Schema definitions describe the data models behind the API. We profile them so the shapes are validatable on their own — useful long after a single request is forgotten.

Security Posture 3

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

Agentic Access 1

An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
