Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/json/format?text=%7B%22b%22%3A2%2C%22a%22%3A1%7D"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/json/format?text=%7B%22b%22%3A2%2C%22a%22%3A1%7D&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

{
  "formatted": "{\n  \"a\": 1,\n  \"b\": 2\n}"
}
