How this service works

Machine-readable contract for active Forest paid capabilities. Unsigned paid calls return HTTP 402 with a PAYMENT-REQUIRED x402 challenge.

Output

Returns the transformed string — either the Base64-encoded representation of the input UTF-8 text, or the decoded UTF-8 text recovered from a valid Base64 input. The service performs the transform locally and returns a result or a clear error if the input is invalid, non-UTF-8, or exceeds the 100 KiB size limit.

Example use cases

Encode API token for HTTP header

“I need to Base64-encode this string using standard mode so I can put it in an Authorization header: 'myuser:mysecretpassword'”

Decode Base64 config blob

“Can you decode this Base64 string back to plain text for me? It's in standard format: 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9'”

URL-safe Base64 for web token

“Encode this JSON string as URL-safe Base64 so I can safely embed it in a URL parameter: '{"user_id":42,"role":"admin"}'”

Technical details

Endpoint

POSThttps://http--forest-gas-station-mainnet--lcjl27p8lmjs.code.run/text/base64?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need a fast, deterministic, server-side Base64 encode or decode with strict UTF-8 and size validation, and you want to avoid bundling a local library or running untrusted transform code. It handles both standard and URL-safe Base64 variants explicitly, making it suitable for preparing URL query parameters, HTTP headers, or data payloads in agent pipelines.

Side effects

Input exceeds 100 KiB limit — rejected with a size error
Decode mode receives an invalid Base64 string — rejected with encoding error
Decoded bytes are not valid UTF-8 — rejected with UTF-8 validation error
Missing or invalid mode field — request rejected
Missing value field — request rejected
Network or payment failure (HTTP 402 if payment not attached)
