How this service works
Paid x402 utilities and live intelligence for autonomous agents: hashing/encoding plus public web lookup, domain intelligence, API discovery audit, evidence extraction and x402 health.
Output
Returns a JSON object with the base64-encoded string in the 'data' field, the encoding type ('base64') confirmed in 'encoding', and the number of input bytes in 'input_bytes'.
Example use cases
Encoding credentials for HTTP auth
“I need to base64-encode the string 'username:password' so I can use it in a Basic Authorization header — can you do that?”
Serializing payload for API transport
“Please base64-encode this JSON payload text so I can safely embed it inside another request body: '{"event":"user_signup","id":42}'”
Encoding a webhook secret
“Can you base64-encode my webhook secret string 'sk_live_abc123xyz' so I can store it in an environment variable safely?”
Technical details
Endpoint
POSThttps://capi2-demand-tools.onrender.com/v1/base64/encodeWhen to prefer
Choose this endpoint when your agent needs a pay-per-call, stateless base64 encoding utility accessible over HTTP without managing a local library — especially useful in sandboxed agent environments where running native code is restricted or when integrating with x402 micropayment workflows.
Side effects
- Empty or missing 'text' field returns a validation error (minLength:1 enforced)
- Non-UTF-8 or binary input may cause encoding errors
- Payment failure via x402 protocol prevents processing
- Service unavailability on Render free tier may cause cold-start latency or downtime
