SDKs & Libraries

Client libraries and code examples for integrating CrawlKit into your applications. Build data pipelines, deploy spiders, run enrichment, and analyze websites in your language of choice.

Official SDKs are coming soon. The packages below show the planned installation paths. In the meantime, every example uses the REST API directly — copy-paste ready with no dependencies.
🔵

TypeScript SDK

Fully typed client with generics, async/await, and typed error handling. Best for Node.js backends, Next.js API routes, and Deno. npm install @crawlkit/sdk

 🅐

JavaScript SDK

Lightweight fetch-based client for Node.js and browsers. Zero dependencies, built-in retry logic, and streaming support. Works everywhere fetch is available.

 🐍

Python SDK

Sync and async clients with requests and httpx. Pandas integration for dataset export. Ideal for data science, automation scripts, and Jupyter notebooks. pip install crawlkit

 ⚙

Rust SDK

Async reqwest-based client with serde deserialization and typed errors. First-class tokio support. cargo add crawlkit-client

 💻

curl Examples

Copy-paste curl commands for every major endpoint group. Includes jq recipes for parsing responses and shell scripts for automation. No SDK required.

Quick Comparison

SDK Runtime Async Types Best For
TypeScript Node.js, Deno, Bun async/await Full generics Production backends, type-safe integrations
JavaScript Node.js, Browser async/await — Quick scripts, browser apps, prototyping
Python CPython 3.9+ asyncio + httpx Type hints Data science, automation, Jupyter notebooks
Rust Native tokio Full structs High-performance services, CLI tools
curl Any shell — — Testing, CI/CD scripts, quick debugging

Authentication

All SDKs authenticate with a Bearer token in the Authorization header. Get your API key from the CrawlKit dashboard.

Authorization: Bearer ck_live_YOUR_API_KEY

See the Authentication guide for details on API key vs. JWT auth, subscription tiers, and local development setup.

Base URL

All API requests use the base URL:

https://api.crawlkit.app/api/v1/
