Similarweb API pricing and the alternative for agencies that want a published price
Similarweb does not publish a price for its API. Access is billed in data credits, each endpoint has its own credit cost, and the amount depends on a quote from sales, either as part of a Business or Enterprise package or as a standalone API package. SeoData Agency lists its price: 149 USD per month on yearly billing (299 USD monthly) with 100 000 API rows, 10 seats and white-label PDFs, so you know the bill before you start.

Similarweb API pricing at a glance
Similarweb is a market intelligence platform. Its API covers traffic and engagement, keyword analysis, app analysis, technographics and company data, and it also offers a Batch API for large historical pulls. You pay in data credits for the data returned rather than for a fixed number of calls, and credits normally reset monthly. The credit allowance, the cost per credit and any minimum term are not on the public pages, so the price you pay is whatever sales quotes. Choose Similarweb when you need its panel-based traffic and app data across many markets. Choose SeoData when the work is SEO for client sites and you want backlinks, keywords, daily positions and audits with seats and branded reports in one published price.

Where Similarweb wins: it is built for market-level questions such as which competitors a category leader draws visitors from, how an app is growing, or which technologies a prospect runs. If those are the questions your clients pay you to answer, SeoData is not a replacement.
Why a quote-only credit model is hard to plan around
Without a published rate you cannot cost a client workload before you commit. You find out the cost per endpoint in the API reference, then estimate how many calls a weekly refresh makes for each client, then ask sales what a credit costs. Similarweb offers a Request Validate endpoint that estimates the cost of a large query before you run it, which helps once you have access. For a retainer you quote this month, a price list beats a sales call. On SeoData a row is a row, and the number left comes back in every API response.
Why agencies look beyond a quote-only API
- The work is SEO. Clients ask about links, rankings and keywords, which the SEO API returns directly.
- Reports need your brand. White label SEO reports are part of the Agency plan.
- Your team needs an interface. The SEO software for agencies workspace gives account managers a place to work without writing code.
- You want traffic context too. The website traffic checker shows estimated organic traffic, top pages and trend for any domain.
What 20 client dashboards cost on each model
An agency refreshes 20 client dashboards weekly with link, keyword and position data. On Similarweb that workload is a custom quote, and the API does not cover backlinks or rank tracking, so a second tool is needed for those. On SeoData Agency the same load uses a fraction of the 100 000 rows, and the bill is 149 USD per month on yearly billing with seats and reports included. For other vendors see the SE Ranking API pricing ladder, the Semrush API pricing breakdown, the Moz API pricing tiers and the Ahrefs API alternative, or compare plans on SeoData pricing.
