Serpstat API review
Simplest credit model
Serpstat is a full SEO platform that happens to expose most of itself through an API. Keyword research, backlinks, rank tracking, competitor analysis and site audit are all reachable programmatically, which makes it a reasonable single source for an agency dashboard.
Its best feature is the billing model. One credit equals one API request, with no field multipliers and no per-row increments. After modelling a two-part DataForSEO bill or an Ahrefs unit calculation, that simplicity is worth something real.
Who Serpstat API is for
Small and mid-sized agencies that want platform and API from one vendor without four-figure pricing. The Team plan at $100 a month is the entry point, since the cheaper Individual plan carries no API access at all.
Strengths and limits
What it does well
- One credit per request. No multipliers, no row increments, no modelling required to forecast a bill.
- Broad coverage from one vendor: keywords, links, ranks, competitors and audit all in a single API.
- Materially cheaper than Ahrefs or Semrush for comparable breadth.
- The platform interface is included, so non-technical team members are not locked out of the same data.
Where it falls short
- The $50 Individual plan has no API access, so the real entry point is $100 a month on Team.
- Data depth is behind Ahrefs and Semrush across most datasets, particularly backlinks.
- Smaller community than the market leaders, so there are fewer worked examples and libraries to borrow.
Serpstat API pricing
API access starts on the Team plan at $100 a month on annual billing, which carries 200,000 to 400,000 credits. Team x2 is $169 a month for 400,000 credits and Agency is $410 for 2 million. The $50 Individual plan does not include API access.
One credit is one request regardless of what comes back, which makes capacity planning genuinely simple: count your daily calls, multiply by thirty, pick the plan above it.
Verdict
A sensible middle option for agencies that want one vendor for both the interface and the API without paying market-leader prices. The credit model is the most transparent here. Choose it over SE Ranking only if you prefer the platform, because SE Ranking currently offers more for less, particularly on AI search.
