Why edge-native?

Built different,
by design

Rust/WASM performance

No JIT warmup. No garbage collector pauses. Rust compiled to WebAssembly executes at near-native speed from the very first request. Cold starts under 5ms, always.

Cloudflare global edge

Your request is routed to the nearest of 300+ points-of-presence worldwide. No central server, no cross-continent round-trips. Latency is a solved problem.

10–200× cheaper

Serverless edge compute eliminates infrastructure overhead. We pass the savings to you. Crypto hashing at $0.10/1K requests isn't a promotional rate — it's the real cost structure.

Frequently asked

Questions,
answered.

What is Oxide APIs?
Oxide APIs is a collection of utility HTTP APIs — cryptographic hashing, data validation, barcode and QR generation — implemented in Rust, compiled to WebAssembly and deployed to Cloudflare Workers' 300+ edge locations. Cold starts run under 5 ms and pricing is 10–200× lower than legacy SaaS equivalents.
How do I get an API key?
Every API is distributed through RapidAPI. Subscribe to any free or paid plan on the RapidAPI marketplace, and your X-RapidAPI-Key is generated instantly. The same key works across all Oxide APIs.
Why is it so much cheaper than the competition?
Edge-native Rust/WASM eliminates the cost drivers of traditional API hosting: no idle servers, no JIT warm-up, no garbage-collection overhead. We pay Cloudflare a fraction of a cent per request and pass the savings on.
How fast are the APIs?
Cold starts are under 5 ms because WebAssembly has no JIT phase. Hot paths typically resolve in 1–3 ms inside the Worker. End-to-end latency depends on the user's distance to the nearest of Cloudflare's 300+ points of presence — usually 15 ms or less globally.
Do you support bcrypt and Argon2 for password hashing?
Yes. The Hash & Encryption Toolkit supports bcrypt (cost factor 12) and Argon2id, plus SHA-256/512, BLAKE3 and MD5. Verification is timing-safe.
Is there a free tier?
Yes. Every API has a Basic tier with 500–1,000 free requests per month and no credit card required.
