Introduction
Welcome to the Pulse API. This guide covers authentication, your first request, and how to handle common errors.
InfoThis is the v2 API. Integrations on v1 keep working until 2027.
Quick Start
Install the SDK, then set your API key as an environment variable before making your first call.
- Create an account and grab your API key
- Install the SDK for your language
- Send your first request
Authentication
Every request must include your API key in the Authorization header.
WarningNever expose your API key in client-side code. Route browser apps through a server-side proxy instead.
Rate Limits
Free plans allow 60 requests per minute. Paid plans scale up to 6,000 per minute.
TipCache read-heavy endpoints on your side to stay well under your limit.
Errors
The API returns standard HTTP status codes with a JSON error body.
- 400 — invalid request
- 401 — missing or invalid API key
- 429 — rate limit exceeded
