Developer resources

Everything needed to send traces programmatically, in one place.

API reference

The ingest API is described by an OpenAPI specification covering /v1/traces, /v1/logs, /v1/metrics, and /health on ingest.telemetry.dev.

Authentication

Send an Authorization: Bearer header with a project API key (td_live_...). Keys are created in the dashboard under a project's API keys page and apply to one environment or to all environments.

Quickstart

Install @telemetry-dev/sdk (npm) or telemetry-dev (PyPI), or point any OpenTelemetry exporter at the endpoint. Setup guides for Vercel AI SDK, LangChain, Claude Code, OpenTelemetry, and more live under integrations.

Versioning and deprecation policy

The ingest API is versioned by URL path (/v1). Breaking changes ship under a new /vN prefix while the previous version keeps working; this page and the OpenAPI document announce each deprecation, and deprecated versions answer with a Sunset header once a removal date is set.

For AI agents

Start from llms.txt for a machine-readable site overview, use pricing.md for plan limits, and use sitemap.xml for the full list of pages.
