Preview request

The preview path is rate-limited and does not charge. Production requests use the same parameters and return a standard x402 challenge when no payment signature is present.

  "https://ai-data-marketplace-1042299154756.us-central1.run.app/api/v1/sentiment_bulk?preview=true" \
  --header "content-type: application/json" \
  --data '{"texts":["Love this app!","Crashes on startup.","It's okay, nothing special."]}'
