Building an SEO SaaS? You might not need another expensive keyword API subscription.
A question for indie hackers and developers:
How do you currently access keyword data for your applications?
If you're building programmatic SEO pages, content research automation, keyword discovery tools, or an AI-powered marketing product, you probably need structured search data.
We developed the SerpSpur Universal REST API to make this workflow more flexible.
The API provides access to:
Search volume and historical trends.
Keyword difficulty and backlink competition.
CPC and advertising competition.
Search intent and parent topics.
Related keyword clusters.
SERP features and forum weakness signals.
AI Overview-related information.
Bulk keyword enrichment.
It also supports different research depths, from a single keyword to larger semantic clusters.
One feature worth exploring is the 30-day cache Vault mode: cached lookups cost credits, while cache misses return without a credit deduction.
