DataForSEO is a pay-as-you-go SEO data API platform that sells raw SERP, keyword, backlink, on-page, and business data to developers building their own tooling rather than to analysts reading a dashboard. There is no subscription and no seat price: accounts prepay a balance against a $50 minimum, credits never expire, and every call is billed individually — a Standard-queue SERP request costs $0.0006, or $0.60 per thousand, with Priority and Live tiers priced up from there for faster turnaround.
The company positions itself as the infrastructure layer beneath the SEO tool market rather than a competitor to it, claiming 750+ software companies built on its endpoints, ISO/IEC 27001 certification, and a published uptime SLA. Its contrast with 📝Ahrefs and 📝Semrush is structural rather than featural: those platforms bundle data with an interface and charge roughly $129–$140 a month for a seat, while DataForSEO charges for the data alone and leaves the interface to the buyer. SERPs are drawn from Google, Bing, Yahoo, Baidu, and Yandex against an in-house keyword database in the billions. Like 📝OpenSEO, it exposes its endpoints through a 📝Model Context Protocol (MCP) server. A 2026 pricing revision raised rates across several endpoint families while removing the $100 monthly minimum that had gated the Backlinks and LLM Mentions APIs.
Key Features
- SERP API — Structured results from Google, Bing, Yahoo, Baidu, and Yandex across three speed tiers, from a roughly five-minute Standard queue to real-time Live calls.
- Keyword Data and Labs APIs — Search volume, difficulty, and keyword expansion drawn from an in-house database of several billion keywords, available per call or as bulk dumps.
- Backlinks API — Referring-domain, anchor, and link-profile data on the same metered terms; the $100 monthly commitment that once gated access was removed in 2026.
- LLM Mentions API — Tracks where a brand surfaces inside AI-generated answers, the answer-engine analogue of rank tracking, billed per call like every other endpoint.
- MCP Server — Exposes the endpoints as callable tools so an agent can pull live SEO data mid-session instead of a human reading it out of a dashboard.
