Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/base64/encode?text=hello%20world"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/base64/encode?text=hello%20world&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum, Monad, World Chain or Tempo) and retries.

Example result

{
  "base64": "aGVsbG8gd29ybGQ=",
  "base64url": "aGVsbG8gd29ybGQ"
}
