Score an ad script before you spend on it.

Ad creative score rates a UGC or paid-social script on six things that decide whether it works: hook, clarity, call to action, platform fit, pacing and credibility. Then it rewrites the weak parts.

What you get back

• Six scores: hook, clarity, CTA, platform fit, pacing, credibility
• Concrete rewrites for the weak lines
• A risk flag for claims that may break ad policies
• Rule checks first, a model judge for what rules can't see

Call it over HTTP

No account and no API key. The first response is 402 Payment Required with the price; an x402-capable client pays in USDC on Base and retries. You're only charged when the call succeeds.

curl -i -X POST https://api.exepal.com/v1/ad-creative-score \
  -H "content-type: application/json" \
  -d '{"creative":{"platform":"tiktok","script":"POV: you finally found a planner that…"}}'
# → 402 Payment Required (price, network: base, pay-to address)
# An x402 client pays in USDC and retries → 200 with the JSON answer
