Text Paraphrase

by SiteCheck in AI models & inference

x402 APIPassing, checked 3 h ago

Rewrite a text in a chosen tone (neutral, formal, casual, simple, persuasive) and length (shorter, same, longer), keeping its meaning and language. Up to 3 variants. Workers AI (Llama 3.3 70B) writes the rewrite; only the rewritten text is returned. Up to 8,000 characters. Not live-checked: the owner tests it on the Worker after the merge. The model can change nuance, so read the result.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.003.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://api.sitecheck-api.workers.dev/api/text/paraphrase' \
  -H 'content-type: application/json' \
  --data-raw '{"length":"same","text":"The meeting has been moved to Thursday because several people are away.","tone":"formal"}'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
