Free tier with 1,000 credits. Pro from $9.50/month (founding member pricing). Unified credit pool across all APIs.
DataForSEO ToolTraceToolTrace's answer:
ToolTrace combines multiple web intelligence capabilities under one API key and one credit pool. Most competitors offer just scraping or just SEO tools. ToolTrace covers scraping, content extraction, metadata, links, schema markup, SEO audits, sitemaps, and tech stack detection in a single platform. It's also built specifically for AI agent workflows with native integrations for LangChain, LlamaIndex, and MCP.
ToolTrace's answer:
Three reasons: breadth, simplicity, and price. You get a full suite of web intelligence APIs without juggling multiple providers and billing systems. The unified credit pool means you pay once and use any endpoint. Founding member pricing starts at $9.50/month for Pro. And every API has a matching free tool on the site so you can test before writing any code.
ToolTrace's answer:
Developers and small teams building AI agents, RAG pipelines, research tools, and web automation. Also SEO professionals who need programmatic access to on-page diagnostics, schema validation, and tech stack data at scale.
ToolTrace's answer:
I was building AI agents that needed reliable web data and got frustrated maintaining scrapers that broke every time a site updated its layout. I built an API to solve my own problem, then realized the same infrastructure could power SEO audits, metadata extraction, link analysis, and tech stack detection. ToolTrace grew from one endpoint into a full platform.
ToolTrace's answer:
Python 3.12, FastAPI, Playwright (headless Chromium for browser rendering), Redis, SQLite, and Astro for the website. Runs on a VPS behind Cloudflare.

I asked it to integrate with https://dataforseo.com/ api which is 10x cheaper than the ahrefs or semrush apis (it's real data). - Source: Hacker News / almost 2 years ago
So far I used dataforseo.com to get the data I need (they have a large database with 4.8 billion keywords), and I could create some cool tools with it! I share the first version of the tutorial on my website called amigocci.io but I started to make it only 2 months ago so I'm still figuring it out and trying to find the best way to make analysis with it.

I can't think of any free tools, but there are some APIs out there that are pretty cheap like https://dataforseo.com/ or https://serpapi.com/pricing. Source: over 3 years ago
Dataforseo.com you can get the same data as SEMrush and other similar tools. Source: over 3 years ago
I like to think that I'm typically aware of great tools to aid in SEO but I was just informed of one that's a game changer. https://dataforseo.com/. Source: over 3 years ago
