I built 18 free, no-signup APIs for common utilities

说明与用途

开发者创建了18个免费、无需注册的API，整合了常用工具（哈希、邮箱验证、UUID生成等），托管在Cloudflare边缘网络，消除了对多家第三方服务的依赖，简化了集成流程。

问题

Developers repeatedly need simple utilities (hashing, email validation, UUID generation, etc.) but must either write boilerplate or sign up for multiple services with keys, rate limits, and credit cards.

结果

Developers can replace multiple paid or custom utilities with a single free API, reducing setup time, eliminating keys, and simplifying maintenance.

工作流

• 1. Identify required utilities. 2. Call the corresponding Presend endpoint via HTTP (e.g., GET /api/[email protected]). 3. Consume the JSON response in your application. 4. Optionally use the npm client (presend-api) to wrap calls.
• 5. For batch operations, use POST /api/url-clean with up to 100 URLs.
• 6. Monitor rate limits (20‑60 req/min per IP) and handle errors from dependent services like crt.sh.
• 7. Integrate into CI pipelines or client code as needed.

"No signup, no key, no dashboard to configure. You just call the endpoint."

"Everything runs on Cloudflare's edge network, so latency is generally low no matter where you're calling from."

"No SLA. This is a free, fair-use service running on Cloudflare's free tier. Endpoints are rate-limited (typically 20-60 req/min per IP)"
