SISTRIX API review
Best European coverage
SISTRIX is the standard SEO dataset in German-speaking markets, and its Visibility Index is treated there roughly the way Domain Authority is treated in English-speaking ones: as the number everyone quotes. The historical series behind it goes back far enough to be genuinely useful for diagnosing algorithm impact.
The API exposes keyword, link, on-page and visibility data on a credit system. Credits are allocated weekly from the Plus package upward, which is an unusual cadence and one you need to design your job schedule around.
Who SISTRIX API is for
Agencies and in-house teams working German, Austrian, Swiss or wider European markets, where SISTRIX coverage beats the US-centric providers. Outside Europe there is little reason to choose it.
Strengths and limits
What it does well
- The best German and European SERP coverage available, well ahead of the US-centric alternatives.
- Visibility Index history long enough to correlate ranking changes with specific algorithm updates.
- Broad endpoint coverage across keywords, links, on-page and visibility from one credit balance.
- Widely recognised in European markets, which makes its numbers persuasive in client reporting.
Where it falls short
- Weak outside Europe. For US-focused work the mainstream providers are better.
- Credits are allocated weekly rather than monthly, so a heavy batch job can exhaust the week's allowance early.
- API access needs the Plus package or above, and pricing is quoted in euros with credit top-ups on top.
SISTRIX API pricing
Credits are the unit, allocated weekly from the Plus package upward, and consumed by both interface exports and API calls. Additional credits cost around €75 a month for 10,000 extra per week.
The weekly cadence is the thing to plan around. A monthly batch job that would sit comfortably inside a monthly allowance can blow through a single week's, so spread scheduled work across the month rather than running it all on the first.
Verdict
The right choice for European work and largely beside the point elsewhere. If you report on German-speaking markets, the Visibility Index is the metric clients already know and the historical depth is real. For US-focused SEO, spend the money on DataForSEO or SE Ranking instead.

SISTRIX's headline metric, tracking a domain's aggregate ranking visibility over time. In German-speaking markets it is the standard reference number, and its long history makes it useful for correlating traffic changes with algorithm updates.Is SISTRIX good for US SEO?
Not particularly. Its strength is German, Austrian, Swiss and wider European coverage. For US-focused work the mainstream providers have better data at a better price.How do SISTRIX credits work?
They are allocated weekly rather than monthly, and shared between interface exports and API calls. Schedule batch jobs across the month rather than running them all at once, or a single job can exhaust a week's allowance.SISTRIX or Semrush for European markets?
SISTRIX for German-speaking markets specifically, where its coverage and the recognition of the Visibility Index both count. Semrush covers more countries overall, so for pan-European work spanning many markets it may still be the better fit.
