How this service works
$0.0002/MB. Base64 encode or decode a string — simple, bounded, fast. 1¢ x402 min; remainder auto-credits — relaystation.ai/penny
Output
Returns the base64-encoded or base64-decoded version of the input string. The response is a simple, bounded text result — the transformed string — delivered synchronously with no side effects.
Example use cases
Encode payload for API auth
“Base64-encode this credential string for me so I can put it in a Basic Auth header: 'myusername:s3cr3tpassword'”
Decode received base64 message
“I got this base64 string from a webhook and I need to know what it says — can you decode it? SGVsbG8gZnJvbSBSZWxheVN0YXRpb24h”
Prepare image data for embedding
“Take this raw image data string and base64-encode it so I can embed it in an HTML img src tag as a data URI.”
Technical details
Endpoint
POSThttps://api.relaystation.ai/v1/utils/base64When to prefer
Choose this endpoint when you need a reliable, metered, no-setup base64 encode/decode operation within an agentic workflow that already uses x402 micropayment infrastructure. Ideal for one-off conversions where spinning up a local utility is unnecessary or unavailable in the execution environment. The per-MB pricing makes it cost-effective for small strings (typical API payloads).
Side effects
- Invalid base64 input when decoding (malformed characters or incorrect padding) — returns an error response
- Oversized payload exceeding size limits — may return a payload-too-large error
- Missing or malformed request body — returns a 400-level error
- Payment/x402 failure if insufficient USDC balance — call is rejected before processing
