Reimagining how developers can ethically access, search, and interact with millions of professional profiles.
As the digital world becomes increasingly fragmented, OPD is building a unified identity layer that puts users in control while enabling developers to build powerful tools and experiences.
Open Identity Protocol - A standardized way to discover and interact with profiles across the web.
AI-Mediated Access - AI doubles act as intelligent gatekeepers, protecting user privacy while enabling innovation.
User-Controlled Data - Every individual decides what information is public, private, or accessible via API.
Ethical API Design - Built with privacy and consent at its core, not as an afterthought.
Query millions of profiles with advanced filters for skills, location, availability, and more. Results are determined by user-defined visibility settings.
Access individual profiles in JSON format through simple RESTful endpoints, with data visibility controlled by profile owners.
Interact with user's AI representation to request information, schedule meetings, or make proposals - all filtered through user-defined preferences.
Establish connections between users, allowing for richer data access based on relationship context and user preferences.
Discover the right people with powerful, ethical, and consent-based search capabilities.
Search by specific skills, technologies, or areas of expertise with support for skill levels and verification status.
skills: ['react', 'typescript'], skill_level: 'advanced', verified: true
Filter by location, timezone, remote status, and current availability for different types of work.
location: {
city: 'Berlin',
remote: true,
radius_km: 50
},
available_for: ['freelance', 'consulting']
Search across industries, company sizes, roles, seniority levels, and professional interests.
industry: 'healthcare',
roles: ['CTO', 'VP Engineering'],
experience_years: { min: 5 }
// Natural language query example
const response = await fetch('https://api.opd.email/search/semantic', {
method: 'POST',
headers: { 'Authorization': 'Bearer YOUR_API_KEY' },
body: JSON.stringify({
query: "Find product designers with experience
in healthcare apps who are open to contract work
in the next 3 months and are in European timezones",
limit: 20
})
});
Our AI can interpret natural language requests and convert them into structured queries, making complex searches intuitive.
Results are filtered based on the searcher's relationship to profiles and the context of the request, ensuring relevant matches.
All searches respect user privacy settings. People are only discoverable according to their preferences, and AI doubles protect from unwanted contact.

},

});
AI doubles process incoming messages and respond based on user preferences:
The OPD API uses OAuth 2.0 and contextual permissions for secure, user-controlled access:
// Example of obtaining an access token
const tokenResponse = await fetch('https://api.opd.email/auth/token', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({
"client_id": "YOUR_CLIENT_ID",
"client_secret": "YOUR_CLIENT_SECRET",
"grant_type": "client_credentials",
"scope": "search.basic profile.read"
})
});
OPD's API includes built-in protection against abuse and ensures ethical data usage:
