Create a new project and optionally wire up a database connection, import MDL (schema), seed instructions, and SQL pairs.

Handling Partial Successes

Successful requests that fully succeed return 201 Created.
If the project is created but some sub-steps fail, the API returns 207 Multi-Status and includes error details for the failed steps.
Sensitive fields in connectionInfo are redacted in responses (e.g. shown as ******).

📘
Explanation & Best Practices

Why 207?: The 207 Multi-Status code is appropriate when you want to indicate that part of a request succeeded and part failed—this aligns with its definition in the HTTP spec, particularly in WebDAV and similar contexts.

Redacting sensitive data: It’s standard security practice to mask or redact sensitive fields (like credentials or other private connection info) in API responses.

Basic Usage

Basic parameters

language: use WrenAILanguage codes (e.g., EN, ES, FR, ZH_TW, ZH_CN, DE, PT, RU, JA, KO, IT, FA_IR, AR, NL). Internally these map to human-readable names on UI.
timezone: use a valid IANA time zone name (e.g., Europe/London, America/Los_Angeles). Non-IANA or unsupported zones are rejected.

Request

{
  "orgId": 1,
  "displayName": "Sales Analytics",
  "language": "EN",
  "timezone": "Europe/London"
}

Response

{
  "project": {
    "id": 123,
    "type": "POSTGRES",
    "displayName": "Sales Analytics",
    "createdAt": "2025-09-11T12:34:56Z",
    "updatedAt": "2025-09-11T12:34:56Z",
    "connectionInfo": null,
    "language": "EN",
    "timezone": "Europe/London"
  },
  "status": "succeeded"
}

Create with Connection Test

Set type, provide connectionInfo, and set testConnection to preflight the credentials. If the test fails, you’ll get a 400; if success, normal creation proceeds.

Request (Postgres)

{
  "orgId": 1,
  "displayName": "Ops DWH",
  "language": "EN",
  "timezone": "America/Los_Angeles",
  "type": "POSTGRES",
  "connectionInfo": {
    "host": "db.internal",
    "port": 5432,
    "user": "app",
    "password": "s3cret",
    "database": "warehouse",
    "ssl": true
  },
  "testConnection": true
}

Response (redacted connectionInfo)

{
  "project": {
    "id": 124,
    "type": "POSTGRES",
    "displayName": "Ops DWH",
    "createdAt": "2025-09-11T12:40:00Z",
    "updatedAt": "2025-09-11T12:40:00Z",
    "connectionInfo": {
      "host": "db.internal",
      "port": 5432,
      "user": "app",
      "password": "******",
      "database": "warehouse",
      "ssl": true
    },
    "language": "EN",
    "timezone": "America/Los_Angeles"
  },
  "status": "succeeded"
}

Create with Metadata (MDL)

Provide an MDL manifest to import models (and best-effort relationships/views).

Request (minimal)

{
  "orgId": 1,
  "displayName": "Retail BI",
  "language": "EN",
  "timezone": "Europe/London",
  "mdl": {
    "models": [
      {
        "name": "customers",
        "columns": [
          { "name": "customer_id", "type": "VARCHAR", "notNull": true },
          { "name": "customer_city", "type": "VARCHAR" }
        ],
        "primaryKey": "customer_id",
        "tableReference": { "catalog": "memory", "schema": "main", "table": "customers" },
        "properties": { "displayName": "Customers" }
      }
    ],
    "relationships": [],
    "views": []
  }
}

Response (partial example if some best-effort steps fail)

{
  "project": { "...": "..." },
  "status": "partial",
  "errors": [
    { "resource": "views", "message": "View \"sales_by_city\" failed: question is required" }
  ]
}

Create with MDL, Instructions, and SQL Pairs

Seed instructions and SQL pairs at creation.

Request

{
  "orgId": 1,
  "displayName": "Growth Insights",
  "language": "EN",
  "timezone": "Europe/London",
  "mdl": {
    "models": [
      { "name": "orders", "columns": [{ "name": "order_id", "type": "VARCHAR", "notNull": true }], "primaryKey": "order_id" }
    ],
    "relationships": [],
    "views": []
  },
  "instructions": [
    { "instruction": "Always include order_id in order analysis", "isGlobal": true },
    { "instruction": "Aggregate by month when asked 'by month'", "questions": ["by month", "monthly"] }
  ],
  "sqlPairs": [
    { "question": "Top 10 customers by orders", "sql": "SELECT customer_id, COUNT(*) c FROM orders GROUP BY customer_id ORDER BY c DESC LIMIT 10" }
  ]
}

Response

{
  "project": { "...": "..." },
  "status": "succeeded"
}
