What is GoAnyAPI?
GoAnyAPI brings SEO, website, search and advertising data into one developer platform. Use one API key and a shared credit balance to request structured JSON for traffic and ranking signals, backlinks, keyword research, Google and Bing search results, autocomplete suggestions, Google Trends, and advertising research. Additional APIs cover app reviews, short-video template trends, AI tool listings and web-page-to-Markdown conversion. Explore live and saved examples in the API Tester, then integrate through documented HTTP APIs, MCP or the CLI. Credits are usage-based, with no subscription required; each API page shows its current rate.
Developers use GoAnyAPI when they need several data sources without managing a separate vendor account for each one. A single key authenticates requests. A shared credit balance covers usage across the catalog, so a keyword lookup, a backlink check, a search-results pull, and an ads-research call draw from the same pool. Responses are structured JSON that can drop into SEO research, competitor analysis, and ad intelligence workflows.
The catalog includes traffic and ranking signals, backlink data, and keyword research for planning content and measuring visibility. Search coverage includes Google and Bing results plus autocomplete suggestions. Google Trends is available for demand over time. Advertising research APIs support creative and competitor ad checks. Other endpoints return app reviews, short-video template trends, listings of AI tools, and a conversion of a web page into Markdown.
Documentation is at https://goanyapi.com/docs. MCP integration is documented at https://goanyapi.com/mcp. A CLI is available for the same key and credit model. The API Tester on the site lets you run live calls and reopen saved examples before you write code. Pricing is pay as you go: there is no subscription, and the current credit rate is shown on each API page. Start at https://goanyapi.com. Each request spends credits from that shared balance, and you can read the live rate on the API page before you call an endpoint.
