Security Math Encoded Length Calculator
x402
Security Math Encoded Length Calculator is a paid API for AI agents from security-math.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-21).
Calculates the encoded character length of N bytes in hex, base64, base32, base58, base85, decimal, binary, octal, and optional custom base-N, plus bytes-per-100-characters ratios.

How this service works
Encoded length of N bytes in hex, base64, base32, base58, base85, decimal or any base-N alphabet, and bytes per N characters.
Output
Returns a JSON object with the number of characters produced by encoding the given byte count in hex, binary, octal, decimal, base32 (padded and unpadded), base64 (padded and unpadded), base85, and base58, plus bytes-per-100-characters ratios for major encodings, overhead percentages relative to hex and base64, and optionally a custom base-N length if alphabetSize was provided.
Example use cases
Token storage field sizing
“I'm designing a database schema and need to know how many characters a 16-byte UUID will take when stored as hex, base64 (padded and unpadded), and base58 — so I can pick the right column length.”
API payload size estimation
“If I have 1000 bytes of binary data, how many characters will it take in base64 versus base85, and what's the overhead percentage for each compared to raw bytes?”
Custom base-N encoding length
“How many characters will a 32-byte value produce in a base-62 encoding? Use alphabetSize 62 and bytes 32.”
Technical details
Endpoint
GEThttps://security-math.x402tookit.com/encoded-length?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to precisely calculate how many characters a given number of bytes will occupy across multiple standard encoding schemes (hex, base64, base58, base85, base32, etc.) or a custom base-N alphabet, especially when comparing encoding overhead or planning storage/field sizes in security-sensitive contexts.
Side effects
- Missing required 'bytes' query parameter returns an error
- bytes value out of range (negative or above 1e12) returns a validation error
- alphabetSize outside 2–256 returns a validation error
- Non-numeric bytes value causes a schema validation failure
- Payment not included or insufficient results in HTTP 402
