The 50 Most Valuable Domains to Mine With Unbrowse

Not all websites are created equal when it comes to API mining. Some domains have dozens of rich, structured endpoints that agents query thousands of times per day. Others have a single monolithic page load with no useful API surface.

This is a ranked guide to the 50 most valuable domains for Unbrowse miners. Each entry includes a difficulty rating (how complex the auth and capture process is), an estimated endpoint density (how many routes a full browse session typically discovers), and why the domain matters to AI agents.

How We Ranked These

Value is a function of three variables:

1. Agent demand — How often AI agents need data from this domain
2. Endpoint density — How many distinct API routes a browse session uncovers
3. Auth complexity — More complex auth means fewer competing miners and higher per-route value

Domains with high demand, rich API surfaces, and moderate auth barriers are the sweet spot.

Tier 1: The Giants (Highest Value)

These are the most-requested domains in the Unbrowse marketplace. Every AI agent eventually needs data from at least one of these.

1. GitHub (github.com / api.github.com)

• Difficulty: Low
• Endpoint density: Very High (50+ routes per session)
• Why it matters: Every developer agent needs repo data, issues, PRs, code search, user profiles, and release info. GitHub's REST and GraphQL APIs are extremely well-structured. The shadow API surface mirrors the public API closely but includes additional internal endpoints for trending, recommendations, and activity feeds.
• Mining tip: Browse through different sections — repos, issues, pull requests, Actions, Packages. Each section exposes different API clusters.

2. Google Search (google.com)

• Difficulty: High
• Endpoint density: Medium (10-15 routes)
• Why it matters: The single most requested data source for any AI agent. Google's search results page makes internal API calls for autocomplete, knowledge panels, People Also Ask, and related searches. These structured endpoints are gold for agents that need search data without rendering a full browser page.
• Mining tip: Use different search types — web, images, news, shopping, maps. Each has distinct API endpoints.

3. Reddit (reddit.com / oauth.reddit.com)

• Difficulty: Low-Medium
• Endpoint density: High (30+ routes)
• Why it matters: Reddit is the internet's largest public forum. Agents need subreddit listings, post content, comments, search results, and user profiles. Reddit's internal API is JSON-first and well-structured.
• Mining tip: Browse multiple subreddits, use search, and navigate comment threads. The pagination endpoints are particularly valuable.

4. LinkedIn (linkedin.com)

• Difficulty: High
• Endpoint density: High (40+ routes)
• Why it matters: Professional data is extremely valuable for sales agents, recruiting agents, and research agents. LinkedIn's Voyager API exposes structured profile data, company info, job listings, and connection graphs.
• Mining tip: LinkedIn's anti-bot measures are aggressive. Use your real logged-in session through Unbrowse. The auth complexity means fewer miners compete for these routes — higher earnings per hit.

5. Amazon (amazon.com)

• Difficulty: Medium
• Endpoint density: Very High (60+ routes)
• Why it matters: Product search, pricing, reviews, recommendations, and availability data. E-commerce agents query Amazon endpoints constantly. The internal API surface is massive — product detail pages alone trigger 15+ API calls.
• Mining tip: Browse different product categories, use search with filters, and navigate through reviews and Q&A sections.

Tier 2: Developer Infrastructure

These domains serve the developer ecosystem. Agents building, deploying, and monitoring software need these routes constantly.

6. Stack Overflow (stackoverflow.com)

• Difficulty: Low
• Endpoint density: Medium (20+ routes)
• Why it matters: Code Q&A is the #1 use case for developer agents. Stack Overflow's internal API exposes question search, answer content, vote counts, tags, and user reputation — all structured.

7. npm (npmjs.com)

• Difficulty: Low
• Endpoint density: Medium (15+ routes)
• Why it matters: Package metadata, version history, download counts, dependency trees. Every Node.js agent needs npm data.

Content platforms generate high agent traffic for summarization, monitoring, and analysis.

13. YouTube (youtube.com)

• Difficulty: Medium
• Endpoint density: High (30+ routes)

Mining Strategy by Tier

For Maximum Earnings

Focus on Tier 1-2 domains with the depth strategy. These have the highest agent traffic, so even with competition, volume makes up for it. Spend extended sessions browsing every section and triggering every interaction.

For First-Mover Bonus

Target Tier 5-8 domains. Many SaaS dashboards remain un-indexed. If you have accounts on platforms like Datadog, Mixpanel, or Linear, you are sitting on uncontested mining territory. Browse your dashboards through Unbrowse and lock in the 2x bonus.

For Long-Tail Value

Tier 9-10 domains and niche SaaS tools have low competition and steady demand. Government data portals, in particular, have clean API surfaces that almost no one has indexed.

For Portfolio Diversification

Do not put all your mining effort into one domain. Spread across tiers. A few high-traffic Tier 1 routes for volume, several Tier 5-6 first-mover claims for premium rates, and a handful of niche Tier 8-10 routes for stability.

What to Avoid

Some domains look valuable but are not worth the mining effort:

• Single-page apps with no API calls — Some sites render everything server-side. No shadow APIs to capture.
• Heavily rate-limited domains — If the site aggressively throttles, your endpoints will fail verification checks and lose reliability score.
• Domains with rapidly changing APIs — If the internal API surface changes weekly, your routes will drift and need constant re-mining.
• Sites behind CAPTCHA walls — If every page load requires human verification, the routes are not useful to automated agents.

Getting Started

Pick 5 domains from this list across different tiers. Install Unbrowse (npx unbrowse setup), connect your wallet, and spend 30 minutes browsing each one. Check your discovered endpoints with unbrowse skills list, and watch the marketplace start working for you.

The best time to start mining was when the marketplace launched. The second best time is now — before the first-mover bonuses on your target domains expire.
