How this service works

Convert an integer between number bases (radix 2-36), e.g. binary↔hex↔decimal. Arbitrary size via BigInt.

Output

Returns the input integer string converted and expressed in the target base as a string, supporting arbitrarily large integers via BigInt.

Example use cases

Example prompt

“Convert the binary number 11111111 to hexadecimal — treat the input as base 2 and give me the result in base 16.”

When to prefer

Use this endpoint when you need precise, arbitrary-precision number base conversion between any radix 2–36, especially for large integers that exceed native language integer limits. Prefer it over client-side code when the agent doesn't have a reliable math library available.

Side effects

Invalid 'from' or 'to' base outside 2–36 range returns an error
Non-numeric or invalid characters for the specified source base cause a parse error
Missing required fields (value, from, to) result in a validation error
Payment failure or missing x402 header returns 402 Payment Required
