Access levels

No account needed

Search and read all public profiles, verification data, and metadata. Anyone — human or agent — can query OnlyData without authentication.

• Browse and search all public profiles
• Read full profile data (name, headline, about, roles, skills, projects)
• Get verification and provenance JSON for any profile
• Access OpenAPI spec, llms.txt, MCP manifest, sitemap

With account (API key)

Create an account at /join, then generate an API key in your profile settings. With a key you can:

• Create and update your own profile
• Set availability signals (open to recruiting, advisory, partnerships)
• Send and receive messages from other members
• Enable cooperative sharing (opt your profile into partner networks)
• Configure what's shareable (email, phone, signals are all user-controlled)

REST API

Full OpenAPI 3.0 spec at /openapi.json. Key endpoints:

# List all profiles
curl https://onlydata.club/api/profiles

# Get a profile by slug
curl https://onlydata.club/api/profile/jane-doe

# Authenticated request
curl -H "x-api-key: od_your_key" \
  https://onlydata.club/api/me

// List all profiles
const res = await fetch('https://onlydata.club/api/profiles');
const { profiles } = await res.json();

// Authenticated request
const res = await fetch('https://onlydata.club/api/me', {
  headers: { 'x-api-key': 'od_your_key' }
});

import requests

# List all profiles
res = requests.get('https://onlydata.club/api/profiles')
profiles = res.json()['profiles']

# Authenticated request
res = requests.get(
    'https://onlydata.club/api/me',
    headers={'x-api-key': 'od_your_key'}
)

Authentication

Two methods — API key is recommended for MCP integrations and scripts. Supabase JWTs are used for browser sessions.

# API key (recommended)
curl -H "x-api-key: od_your_key" \
  https://onlydata.club/api/me

# Supabase JWT (browser sessions)
curl -H "Authorization: Bearer eyJ..." \
  https://onlydata.club/api/me

// API key
const res = await fetch('https://onlydata.club/api/me', {
  headers: { 'x-api-key': 'od_your_key' }
});

// Supabase JWT
const res = await fetch('https://onlydata.club/api/me', {
  headers: { 'Authorization': `Bearer ${token}` }
});

import requests

# API key
res = requests.get(
    'https://onlydata.club/api/me',
    headers={'x-api-key': 'od_your_key'}
)

# Supabase JWT
res = requests.get(
    'https://onlydata.club/api/me',
    headers={'Authorization': f'Bearer {token}'}
)

Domain Verification

Prove ownership of a company domain to get a verified badge. Three methods available — pick whichever fits your setup. Verified companies also auto-elevate team members whose email domains match.

Step 1: Get instructions

curl https://onlydata.club/api/verify-domain/instructions/your-company

Step 2: Choose a method

Step 3: Trigger verification

# DNS verification
curl -X POST https://onlydata.club/api/verify-domain/your-company \
  -H "x-api-key: od_your_key" \
  -H "Content-Type: application/json" \
  -d '{"method": "dns"}'

# File verification
curl -X POST https://onlydata.club/api/verify-domain/your-company \
  -H "x-api-key: od_your_key" \
  -H "Content-Type: application/json" \
  -d '{"method": "file"}'

# Meta tag verification
curl -X POST https://onlydata.club/api/verify-domain/your-company \
  -H "x-api-key: od_your_key" \
  -H "Content-Type: application/json" \
  -d '{"method": "meta"}'

const res = await fetch('https://onlydata.club/api/verify-domain/your-company', {
  method: 'POST',
  headers: {
    'x-api-key': 'od_your_key',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({ method: 'dns' })
});

import requests

res = requests.post(
    'https://onlydata.club/api/verify-domain/your-company',
    headers={'x-api-key': 'od_your_key'},
    json={'method': 'dns'}
)

On success

• Profile gets verified status with green badge
• Verification proof stored in profile_data.domain_verification
• Team members with matching email domains are auto-elevated to verified

Admin override

Admins can verify any profile directly — no DNS/file check needed:

curl -X POST https://onlydata.club/api/admin/verify/your-company \
  -H "x-admin-key: YOUR_ADMIN_KEY" \
  -H "Content-Type: application/json" \
  -d '{"status": "verified", "domain": "yourcompany.com"}'

MCP tool

Agents can verify domains through the MCP server:

// Get instructions (omit method)
{ "tool": "verify_domain", "args": { "slug": "your-company" } }

// Attempt DNS verification
{ "tool": "verify_domain", "args": { "slug": "your-company", "method": "dns" } }

Agent Readiness Scores

Every OnlyData profile with a website is scanned for agent-readiness signals. Scores range 0–100 across six categories:

# All scores (ranked)
curl https://onlydata.club/api/agent-readiness

# Single profile
curl https://onlydata.club/api/agent-readiness/producthacker

// All scores
{ "tool": "get_agent_readiness" }

// Single profile
{ "tool": "get_agent_readiness", "args": { "slug": "producthacker" } }

Scans run on a periodic schedule. Scores include an AI-generated summary and full check details per profile.
