# Start the agent
npx @apitree/connector start

How It Works

flowRequest path

Buyer calls apitree proxy
        ↓
apitree forwards to your agent (HMAC signed)
        ↓
Agent queries your DB (read-only, parameterized)
        ↓
Response returned through apitree proxy
        ↓
You earn 80% of API call revenue

Supported Databases

PostgreSQL — Full support (primary)
MySQL / MariaDB — Full support
More coming: MongoDB, MSSQL, Oracle

Security

Read-only database connections enforced at adapter level
Column/table whitelist — only selected fields are queryable
PII auto-detection (Korean RRN, phone, email, credit card, SSN)
HMAC-SHA256 request signing between apitree and agent
Encrypted config file (~/.apitree/connector.json via AES-256-GCM)
Parameterized queries — zero SQL injection risk

Query API

Once your agent is running, buyers can query your data through the apitree proxy:

bashcurl

# List records with filters
curl "https://apitree.ai/api/v1/proxy/your-data?filter[city]=Seoul&sort=price&order=desc&limit=10" \
  -H "Authorization: Bearer nxs_live_YOUR_KEY"

# Response
{
  "data": [
    { "id": 1, "city": "Seoul", "price": 450000000, "area_sqm": 85 }
  ],
  "meta": { "total": 1523, "limit": 10, "offset": 0 }
}
