How this service works
A compact x402 utility surface for agents that need cheap, repeatable non-LLM transformations before spending on heavier routes: CSV cleanup, JSON Schema checks, timestamp conversion, JWT decode, URL normalization, hashes, codecs, and text utilities.
Output
Returns a JSON object with ok=true, the tool name ('base64-codec'), the echoed input (mode and text), the route used, and a result object containing the mode applied, the byte length of the input, and the output string (encoded or decoded). The response is deterministic for the same input.
Example use cases
Encode API credentials for auth header
“I need to Base64-encode the string 'myuser:mypassword' in encode mode so I can use it in a Basic Authentication header.”
Decode an unknown Base64 payload
“Can you decode this Base64 string for me using decode mode: 'eDQwMiB0b29scw=='? I need to see what the original text says.”
Prepare text for embedded JSON transmission
“Encode the text 'Hello, World! Special chars: <>&' to Base64 encode mode so I can safely embed it in a JSON field without escaping issues.”
Technical details
Endpoint
POSThttps://x402-utils.558686.xyz/v1/tools/base64-codec?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap ($0.002 USDC), deterministic, repeatable Base64 encode/decode operation without spinning up an LLM or a full data pipeline. It is ideal for agents that need to prepare strings for HTTP headers, embed data in JSON, or decode opaque payloads as a preprocessing step before heavier operations.
Side effects
- Invalid mode value (not 'encode' or 'decode') may result in an error or unexpected output
- Missing 'text' field returns an error response
- Malformed Base64 input in decode mode may return a decoding error
- Payment failure (402) if x402 micropayment is not properly attached
- Network timeout on the upstream host
