How this service works
Buyer-first MCP procurement gateway that discovers, compares and routes live x402 APIs without making the buyer choose a provider.
Output
Returns a JSON object containing the transformed output string, the operation performed (encode or decode), the input byte count, a product identifier ('kevaremesh_base64_transform_v2'), the service name ('KEVAREMESH'), and a timestamp of when the result was generated.
Example use cases
Encoding credentials for HTTP auth
“I need to base64-encode the string 'myuser:mypassword' so I can use it in a Basic Authorization header — can you run that encode operation through KEVAREMESH?”
Decoding a mystery base64 payload
“I got this base64 string 'SGVsbG8sIFdvcmxkIQ==' in an API response and I can't read it — can you decode it back to plain text using the KEVAREMESH base64 transformer?”
Encoding a JSON config blob
“Encode this JSON string '{"api_key":"abc123","env":"prod"}' to base64 using KEVAREMESH so I can embed it safely in a URL parameter.”
Technical details
Endpoint
POSThttps://kevaremesh-web.vercel.app/api/x402/base64-transform?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-use base64 encode or decode operation without provisioning your own infrastructure, especially within an x402 micropayment-enabled agent workflow. It is best suited for UTF-8 text payloads under 256KB where simplicity and low cost per call ($0.001 USDC) matter more than high-volume batching.
Side effects
- Non-UTF-8 binary input will be rejected (UTF-8 text only limitation)
- Text exceeding 262,144 characters will fail input validation
- Invalid operation enum value (anything other than 'encode' or 'decode') will cause a schema error
- Payment failure via x402 protocol will prevent the call from executing
- Malformed base64 input string when decoding will produce an error
