How this service works
Crypto, AI, Social Media, Finance, Weather, Tools & more. Pay per call in USDC on Base. No API keys.
Output
Returns a Base64-encoded representation of the input string, which can be used in HTTP headers, JSON payloads, data URIs, or any context requiring Base64-encoded data.
Example use cases
Encoding API credentials for HTTP headers
“I need to Base64 encode my username and password 'admin:supersecretpassword123' so I can use it in a Basic Auth header — can you encode that string for me?”
Preparing binary payload for JSON embedding
“Can you Base64 encode this raw data string 'image_data_bytes_xyz_raw' so I can safely embed it inside a JSON field without breaking the format?”
Encoding configuration file content
“Take this config value 'host=localhost;port=5432;db=myapp' and Base64 encode it so I can store it safely as an environment variable.”

Endpoint
POSThttps://nexus-api-virid.vercel.app/api/tools/base64/encodeWhen to prefer
Use this endpoint when you need a quick, pay-per-call Base64 encoding operation without managing API keys or setting up a local encoding library — particularly useful inside AI agent workflows on Base that already use USDC micropayments via x402.
Side effects
- Empty or missing input string returns an error
- Malformed input schema returns a 400 bad request
- Payment failure or insufficient USDC balance results in a 402 response
- Very large inputs may be truncated or rejected
