ToolTrace is a developer-first platform of web intelligence APIs. Instead of building and maintaining scrapers, developers get clean, structured data from any public webpage through simple API calls.
Production APIs: - Web Scraping API — extract Markdown, text, and HTML with static or browser rendering - Content Extraction API — pull clean article content from any URL - Metadata Extraction API — titles, descriptions, Open Graph, Twitter Cards - Link Extraction API — all links from a page, classified and normalized - Schema Extraction API — JSON-LD structured data from any page - SEO Audit API — on-page SEO diagnostics and scoring - Sitemap Inspector API — parse and validate XML sitemaps - Tech Stack Detection API — identify technologies across 16 categories
Built for AI agents with native integrations for LangChain, LlamaIndex, MCP, CrewAI, and Vercel AI SDK. RAG-ready chunked output. Handles JavaScript-rendered pages with headless browser rendering.
Free tier with 1,000 credits. Pro from $9.50/month (founding member pricing). Unified credit pool across all APIs.

ToolTrace'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 often use the Hunter Google Chrome extension to assist me in discovering the contact details of new outreach targets. The only drawback is that I quite often exceed my free monthly allowance of lead requests.

A few things worth flagging: PDL beats Clearbit's historical rates for US and Western European companies, but drops to ~52% match rate for Japan and South Korea specifically. Apollo underperforms on raw company matching but returns significantly more contacts per domain in Prospector-style queries than Clearbit's Prospector ever did — the tradeoff is more stale titles in the result set. Hunter.io is fast and cheap... - Source: dev.to / 3 months ago
The real conclusion I'd push back on from every vendor comparison I've read: there is no single tool that solves reverse lookup at 80%+ accuracy with clean data. The waterfall is the answer. The question is whether you build it yourself with PDL + Hunter.io + Prospeo, or use a platform like Clay to abstract the plumbing — and whether you're willing to pay FullEnrich's premium for that abstraction. - Source: dev.to / 4 months ago
Last year I ran the same LinkedIn Sales Navigator export through three enrichment APIs. Apollo matched 61% of the emails. Hunter.io matched 54%. An OSINT-first pipeline I'd built in n8n — pulling from public sources before hitting any paid API — matched 79% and cost roughly $0.003 per contact. The delta wasn't magic. It was sequence. - Source: dev.to / 4 months ago
Start with diligent email list hygiene. Remove invalid, dormant, or unengaged addresses regularly. Use free verification tools like NeverBounce or Hunter.io — many of which offer limited free API calls — or build your own heuristics. - Source: dev.to / 7 months ago
By putting a mailto link out there, you also share your contact details with any legitimate outreach specialists that wish to reach you. Finding all your company emails hidden in the html code is as easy as a single tap on a hunter.io widget (many similar tools are also available). - Source: dev.to / almost 2 years ago
