Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/json/to-csv?text=%5B%7B%22name%22%3A%22Ada%22%2C%22age%22%3A36%7D%2C%7B%22name%22%3A%22Alan%22%2C%22age%22%3A41%7D%5D"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/json/to-csv?text=%5B%7B%22name%22%3A%22Ada%22%2C%22age%22%3A36%7D%2C%7B%22name%22%3A%22Alan%22%2C%22age%22%3A41%7D%5D&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

{
  "csv": "name,age\nAda,36\nAlan,41",
  "rows": 2,
  "columns": 2
}
