Number Base Conversion API

The Number Base Converter is available as a REST API for scripts, CI pipelines, and automated workflows. Send a JSON body with the number and its base; receive all four representations in the response. No API key required.

Step-by-step guide

1. Send a POST request: POST to https://quickhelp.dev/api/number-base-converter with Content-Type: application/json.
2. Set the input fields: Set input to your number as a string, and from_base to 2, 8, 10, or 16.
3. Parse the response: The response JSON contains decimal, binary, octal, and hexadecimal fields with all converted values.
4. Use grouped fields for readability: binary_grouped and hex_grouped split values into nibbles and bytes — useful for logs and reports.

Frequently asked questions

What does the API request look like?

curl -X POST https://quickhelp.dev/api/number-base-converter -H 'Content-Type: application/json' -d '{"input":"FF","from_base":16}'. The response includes all four representations plus bit_length and is_power_of_two.

Is there a rate limit on the API?

The anonymous free tier has a per-IP rate limit suitable for personal projects and scripts. For higher volume, contact us.

Can I use this in a CI pipeline?

Yes. The API is stateless and deterministic — the same input always produces the same output, making it safe for reproducible CI environments.
