MIME type for a file

$0.003 per call · failed calls are never charged · no account or API key needed

MIME (content) type for a file name or extension, e.g. report.pdf → application/pdf, and whether browsers usually display it inline. Use when uploading or serving files.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/mime?file=report.xlsx"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/mime?file=report.xlsx&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

{
  "extension": "xlsx",
  "mime": "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet",
  "inline": false
}
