File Slot

by Agent File Slot in Documents & files

x402 APIPassing, checked 2 h ago

Get a signed upload URL and a retrieval URL for one file, in one call. Your agent PUTs the bytes straight to storage — they never pass through this API, so there is no size ceiling imposed by a serverless runtime and no proxy in the middle. Declare bytes= and the size is signed into the URL. Up to 25 MB, retention 1-30 days, unguessable key. The step every agent hits the moment it produces a report, chart, CSV or build and has nowhere to put it.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.005.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://402.com.tr/api/x402/file-slot?bytes=20480&contentType=text%2Fcsv&name=report.csv&ttlDays=7'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - 'https://402.com.tr/api/x402/file-slot?bytes=20480&contentType=text%2Fcsv&name=report.csv&ttlDays=7' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
