We have just added five new SEO endpoints that fill the most-requested gaps in our keyword and domain coverage. Score keyword difficulty for up to 1,000 keywords at once, pull full keyword metrics (volume, KD, intent, CPC, and backlinks) in a single call, classify search intent, and estimate organic and paid traffic for one domain in detail or 1,000 domains in bulk. Every one is a POST under `/v1/seo/*`, returns clean JSON under the same `{ ok, data }` envelope, uses the same `yep_sk_` key, and is priced per call from $0.02.
What's new
- Bulk Keyword Difficulty — KD (0–100) for up to 1,000 keywords per call
- Keyword Overview — volume, difficulty, intent, CPC, competition, avg backlinks and 12-month trend per keyword
- Search Intent — informational / commercial / navigational / transactional with a confidence score
- Domain Rank Overview — organic & paid traffic, keyword counts, full position distribution and movement (new/up/down/lost)
- Bulk Traffic Estimation — organic & paid traffic + keyword counts for up to 1,000 domains at once
- Same `yep_sk_` key, same `{ ok, data }` envelope, pay per call from $0.02
What you can build with them
Build a keyword research tool that scores difficulty and intent across a whole seed list, prioritize content by KD and search intent, or size up competitors by estimating the organic traffic of a thousand domains in one request. Domain Rank Overview gives you the position-distribution and movement data behind an Ahrefs-style domain report; Bulk Traffic Estimation is built for prospecting and market sizing at scale.
How to call them
Each is a POST under `/v1/seo/*`. Score keyword difficulty for a whole list:
curl -X POST https://api.yepapi.com/v1/seo/keywords/difficulty \
-H "x-api-key: $YEPAPI_KEY" \
-H "Content-Type: application/json" \
-d '{
"keywords": ["seo api", "keyword research api", "backlink checker"]
}'Pricing
Pay per call from your prepaid balance, billed on what you get back: the keyword endpoints and bulk traffic start at $0.02 and scale with the number of items returned; domain rank overview is a flat $0.04. No subscription, no minimums.
