Run it yourself

Open the sample in the playground with the whole request filled in. It runs on your own account, within the budget shown, against the same read-only sample systems.

Budget for this sample: $0.03

How it works

Each theme has a count and at least one verbatim quote, so every claim can be checked against the source file. Praise and complaints are separated, and a response is counted under one theme only.

What the agent can and cannot do

The permissions are part of the request. Anything not listed here is not available to the run.

Setting	Allowed
Connections	None
Web	Off
Shell	Off
Files	feedback.txt (read-only)
Zero data retention	Off: the record is kept for 30 days
Budget	$0.03, a hard cap
Timeout	60 seconds

Credentials never enter the machine: a broker adds them to each call and enforces the methods above.

The code

This is the exact request the sample sends. Set EPHEMERAL_API_KEY to a member key of your organization.

curl -X POST $EPHEMERAL_URL/v1/runs \
  -H "Authorization: Bearer $EPHEMERAL_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $(uuidgen)" \
  -d @request.json

Files in the request

Passed inline, so nothing is uploaded first. The agent sees each one as a read-only file.
