PikaSEO API

Send the key on every request, either way works:

Authorization: Bearer pk_live_xxxxxxxx
# or
x-api-key: pk_live_xxxxxxxx

Runs are billed to your account's credit balance — identical costs to the web UI, and a failed run never charges. New accounts start with 50 free credits; top-ups are on the pricing page.

Example — AI Humanizer:

curl -X POST https://pikaseo.com/api/humanize-text \
  -H "x-api-key: pk_live_xxxxxxxx" \
  -H "Content-Type: application/json" \
  -d '{
    "text": "Your AI-generated text here...",
    "tone": "casual",
    "premiumModel": false
  }'

Example — Keyword Search Volume:

curl -X POST https://pikaseo.com/api/keyword-search-volume \
  -H "x-api-key: pk_live_xxxxxxxx" \
  -H "Content-Type: application/json" \
  -d '{ "keywords": "seo tools, keyword research, backlink checker" }'

Check your balance:

curl https://pikaseo.com/api/billing/balance \
