🔗 Tundra Connect

Vendor API integrations for Deno, Bun, and Node — built on @tundralibs/restler and @tundralibs/guardian

Tundra Connect wraps popular third-party vendor APIs in typed, tested, cross-runtime TypeScript clients. Each connect is an independently versioned package published to JSR under the @tundraconnect scope. Requests and responses are validated at runtime, and failures surface as one typed error class per vendor.

• Payments: Stripe, PayPal, Razorpay, Dodo Payments
• Object storage: AWS S3 and S3-compatible stores (Cloudflare R2, MinIO, DigitalOcean Spaces), Google Cloud Storage, Azure Blob Storage
• Messaging and notifications: Slack, Discord, Telegram, Twilio SMS and voice, SendGrid and Cloudflare email, ntfy push
• Market data and prediction markets: CoinGecko, Open Exchange Rates, Kalshi, Polymarket
• Search, data and operations: Algolia, Upstash Redis, Sentry, OpenWeatherMap
• URL safety: Google Web Risk, URLhaus (abuse.ch)
• Analytics: Google Analytics 4 server-side events (Measurement Protocol)
• Cloudflare platform: DNS records and zones, Cloudflare for SaaS custom hostnames, Turnstile token verification

See CONVENTIONS.md for the shared structure and CONTRIBUTING.md for the workflow.

Runs on Deno, Bun and Node; Web-APIs-only, so it also works on Cloudflare Workers (smoke-tested in CI inside workerd) and in the browser (not CI-verified).
