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 โ extract Markdown, text, and HTML with static or browser rendering - Content Extraction API โ pull clean article content from any URL - Metadata Extraction API โ titles, descriptions, Open Graph, Twitter Cards - Link Extraction API โ all links from a page, classified and normalized - Schema Extraction API โ JSON-LD structured data from any page - SEO Audit API โ on-page SEO diagnostics and scoring - Sitemap Inspector API โ parse and validate XML sitemaps - Tech Stack Detection API โ 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.
We use Apollo with our Sales and BDR team to manage our cold outreach. The strength of the platform is the sequences and cadences that you can set up. Compared to other tools we have used in the past like Salesloft the UI is much easier to navigate. The main limitation is that the quality of data isn't as vast and often I can find prospects on Linkedin but not in Apollo.

Personal email domains destroy this. Clearbit's Enrichment API returns a null company when it hits gmail.com. Apollo routes personal domains straight to a consumer bucket and skips B2B fields entirely. Even PDL's /person/enrich endpoint โ the most permissive of the major providers โ gives you around 32% hit rate on Gmail addresses versus 74% on corporate domains. I measured this across 6,200 signups for a... - Source: dev.to / 3 months ago
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 โ the tradeoff is more stale titles in the result set. Hunter.io is fast and cheap... - Source: dev.to / 3 months ago
One thing comparison guides consistently get wrong: Clay is not an enrichment API. It's a waterfall orchestration tool that calls People Data Labs, Apollo, Clearbit, and others in sequence for you. It's useful, but it adds 2โ8 seconds of latency per row in my runs and costs more per match than going direct. For a CRM webhook flow where you need sub-second enrichment calls, Clay is the wrong layer to hit first. - 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 โ pulling from public sources before hitting any paid API โ matched 79% and cost roughly $0.003 per contact. The delta wasn't magic. It was sequence. - Source: dev.to / 4 months ago
Despite having its LinkedIn Page removed in 2025, Apollo remains a functional enrichment and outreach platform with 275M+ contacts. The free tier includes 10,000 credits and the $49/month basic plan is the cheapest entry point for a combined enrichment-plus-sequencing workflow. Apollo's data collection methods have attracted LinkedIn's attention, but the product continues to operate. The risk I'd assign it:... - Source: dev.to / 4 months ago
