x402 APIPassing, checked 4 h ago

Takes an audio or video file by URL or inline base64 and reports who spoke when. Every turn comes back with its speaker label, start and end time, duration, word count and text, and consecutive words from the same speaker are merged into one turn rather than left as a word list.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.025.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://medien.halowerk.com/v1/diarize' \
  -H 'content-type: application/json' \
  --data-raw '{"duration_minutes":1,"language":"en","source":{"url":"https://samplelib.com/lib/preview/mp3/sample-3s.mp3"}}'

# 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 - -X POST 'https://medien.halowerk.com/v1/diarize' \
