README

MockHero

Synthetic test data API. Generate realistic, relational data for any database schema.

What it does

156 field types across 15+ categories (identity, location, financial, temporal, and more)
Relational data — foreign keys just work. Orders reference real user IDs, reviews link to real products. One API call seeds your entire database.
3 input modes — structured schema, plain English prompt, or pre-built templates
Auto-locale — add a country enum field and names, emails, phones match each row's nationality. 22 locales supported.
JSON, CSV, SQL output — Postgres, MySQL, SQLite dialects
Deterministic seeds — same seed + same schema = identical data every time
MCP server — use from Claude Desktop, Cursor, Windsurf, or any AI agent

Quick start

curl -X POST https://mockhero.dev/api/v1/generate \
  -H "Authorization: Bearer mh_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "tables": [
      {
        "name": "users",
        "count": 50,
        "fields": [
          { "name": "id", "type": "uuid" },
          { "name": "name", "type": "full_name" },
          { "name": "email", "type": "email" },
          { "name": "country", "type": "enum", "params": { "values": ["US", "DE", "FR", "JP"] } },
          { "name": "created_at", "type": "datetime" }
        ]
      },
      {
        "name": "orders",
        "count": 200,
        "fields": [
          { "name": "id", "type": "uuid" },
          { "name": "user_id", "type": "ref", "params": { "table": "users", "field": "id" } },
          { "name": "total", "type": "price" },
          { "name": "status", "type": "enum", "params": { "values": ["pending", "shipped", "delivered"] } }
        ]
      }
    ]
  }'

Or use plain English:

curl -X POST https://mockhero.dev/api/v1/generate \
  -H "Authorization: Bearer mh_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "prompt": "50 users with German names and 200 orders linked to them" }'

Templates

Pre-built schemas for common patterns — no schema definition needed:

curl -X POST https://mockhero.dev/api/v1/generate \
  -H "Authorization: Bearer mh_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "template": "ecommerce", "scale": 2, "locale": "de" }'
