API Discovery

Connect your sources

Link your GitHub repositories and API gateways, and install the Treblle SDK. No agents, no config files, no per-service setup.

Treblle inventories everything

Every API is discovered, classified, and tagged with owner, environment, and technology metadata, applied automatically across all three sources simultaneously.

The catalog stays current

New APIs appear when deployed. Decommissioned services fall off. No manual updates, no spreadsheets, no wiki maintenance required.

What is API Discovery?

The automated process of finding every API in your infrastructure

API discovery is the automated process of identifying and cataloging every API operating within an organization's infrastructure, across source code, gateways, and live traffic. In large engineering organizations, APIs accumulate faster than they're documented, creating inventory gaps that expose security risks and block governance efforts. Treblle's API discovery runs continuously across code repositories, API gateways, and traffic data to maintain a structured, always-current record of every API you run.

Buyer's Guide to API Observability

Multi-Source Discovery

Automated API discovery across code, gateways, and cloud

Most organizations discover APIs when something breaks. Treblle scans your GitHub repositories, connects to every major API gateway, and cross-references live traffic, building one inventory across AWS, Azure, GCP, and on-prem simultaneously. No per-cloud tooling. No manual reconciliation.

Code-based API Discovery

Scans GitHub repositories to detect APIs directly from source code, regardless of framework, language, or deployment status.

Gateway-based API Discovery

Connects to any API gateway to inventory every registered API automatically, with no vendor lock-in.

Cross-Cloud Inventory

Discovers APIs across AWS, Azure, GCP, and hybrid environments in a single view, with no per-cloud tooling required.

Automatic Metadata

Complete ownership and metadata, applied automatically

Treblle doesn't just find APIs: it attaches ownership, domain classification, environment tags, and technology metadata to each one. Every team, every environment, every service, organized from the first scan, without a spreadsheet in sight.

Owner Attribution

Associates every API with its responsible team or individual automatically, closing the accountability gap that grows with sprawl.

Automatic Categorization

Groups discovered APIs by domain, business function, and technology stack, giving architects a structured taxonomy without manual effort.

Metadata Mapping

Automatically captures owners, environments, categories, and technologies for each API, with no manual tagging or maintenance.

Shadow API Detection

Surface what's hiding in your infrastructure

Shadow APIs, including undocumented services, zero-traffic endpoints, and deprecated routes still accepting calls, are where breaches start. Treblle surfaces them at the route level, not just the service level, so your security team can act before anyone else does.

Shadow API Detection

Identifies APIs with zero traffic or no documentation that still exist in your infrastructure, eliminating blind spots before they become exposure.

Endpoint Discovery

Maps every individual endpoint across each discovered API, giving route-level visibility rather than service-level awareness alone.

Continuous Discovery

An API inventory that keeps itself current

As services deploy and decommission, the catalog updates itself. New APIs appear the moment they're detected. Removed services fall off automatically. No one has to remember to update a wiki, a spreadsheet, or a Confluence page.

Continuous Discovery

Keeps your API inventory current as new services are deployed or decommissioned: your catalog reflects reality, not a point-in-time snapshot.

Zero Configuration

Discovery runs out of the box. Connect your sources and Treblle does the rest, with no agents, scripts, or config files to maintain.

API Discovery: Common Questions

API discovery is the automated process of identifying and cataloging all APIs in an organization's infrastructure, across source code, gateways, and live traffic. Manual approaches (spreadsheets, wiki pages) fall behind as APIs proliferate. Automated discovery keeps a complete, current record without manual effort.

Treblle connects to three sources simultaneously: GitHub repositories (code-based discovery), API gateways (gateway-based discovery), and live traffic via its lightweight SDK. Each source populates the same inventory, and Treblle reconciles them into a single, deduplicated record with metadata automatically applied.

API discovery is the automated process of finding APIs. An API catalog is the curated, published view of approved APIs made available to consumers. Treblle handles both: discovery feeds the inventory, and teams promote APIs from inventory to the public-facing catalog when they're ready.

Shadow APIs are undocumented or unmanaged APIs operating within your infrastructure: services deployed outside formal processes, deprecated endpoints still accepting traffic, or internal routes exposed unintentionally. Shadow API detection automatically flags these, giving security and platform teams the visibility to address them before they become a risk.

Yes. Treblle discovers APIs across AWS, Azure, GCP, and hybrid on-prem environments in a single inventory view. No per-cloud tooling is required.

No. Treblle's discovery connects directly to your code repositories and gateways. There are no agents to install, no scripts to write, and no configuration files to maintain.
