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

Описание и применение

Разработчик создал 18 бесплатных API без регистрации, объединяющих часто используемые утилиты (хеширование, проверка email, генерация UUID и др.) и размещает их на сети Cloudflare, устраняя необходимость в ключах и ограничениях сторонних сервисов.

Задача

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.

Результат

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

Рабочий процесс

• 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.

Доказательства

"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."

Источник

"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)"
