This reference is for the nerds who want to know all the internals.

Common Concepts

Database name — Always "Space/Database" format, e.g. "SoftDev/bug", "Product Management/feature". Names are case-sensitive. Field name — Always "Space/FieldName" format. The space prefix does not necessarily match the database’s own space. Fields inherited from system apps use their own prefixes: user/name, assignments/assignees, workflow/state, comments/comments, icon/icon. Always derive field names from schema_detailed output, never guess them. fibery/id — Internal UUID for an entity (e.g., "5766cc9a-ae80-4893-82d3-db8b78fdfa13"). Required for updates, state changes, and document operations. Retrieved via query. fibery/public-id — Human-readable string ID (e.g., "13961"). Used in web URLs and get_entity_links. System fields — Auto-populated and read-only: fibery/id, fibery/public-id, fibery/creation-date, fibery/modification-date, fibery/created-by, fibery/modified-by. Formula fields — Always read-only. Identified by the formula: comment in schema_detailed output. Typical sequence for entity work — schema → schema_detailed → query (to get IDs) → write tools.

Workspace & Schema

`schema`

Returns the high-level structure of the workspace: all spaces and their databases, without field details. Parameters — None. Returns — All spaces and database names in the workspace. Example output (excerpt)

space SoftDev {
    database SoftDev/Commit
    database SoftDev/Deployment
    database SoftDev/Dev Task
    database SoftDev/bug
}

space Product Management {
    database Product Management/Insight
    database Product Management/Product Area
    database Product Management/feature
}

Note — Call this first before any other tool. It is the source of truth for valid database names.

`schema_detailed`

Returns field definitions and enum values for specific databases in YAML format. Parameters

Name	Type	Required	Description
`databases`	string[]	Yes	Database names in `"Space/Database"` format
`includeRelatedDatabases`	boolean	No	Also include related databases with their fields. Default: `false`

Returns — Per-database YAML with field names, types, and metadata comments: read-only, formula, collection, UI title, default. Example

{
  "databases": [
    "SoftDev/bug"
  ],
  "includeRelatedDatabases": false
}

Example output (excerpt)

SoftDev/bug: # Bug is an issue in a product.
  fields:
    fibery/id: fibery/uuid                # read-only
    fibery/public-id: fibery/text         # read-only
    fibery/creation-date: fibery/date-time # read-only; default: $now
    user/name: fibery/text                # UI title
    user/Owner: fibery/user               # default: $my-id
    user/urgent: fibery/bool
    user/Product Area: Product Management/Product Area
    user/feature: Product Management/feature
    SoftDev/Regression: fibery/bool
    SoftDev/Created By AI: fibery/bool
    SoftDev/Dev Task: SoftDev/Dev Task
    assignments/assignees: fibery/user    # collection
    workflow/state: workflow/state_SoftDev/bug # default: Icebox
    comments/comments: comments/comment  # collection

Key reading rules for this output

Fields marked read-only or formula: cannot be written.
Fields marked collection require add_collection_items / remove_collection_items to modify.
workflow/state fields require set_state to modify.
Collaboration~Documents/Document fields require set_document_content or append_document_content.
The field name as shown (including its space prefix) is exactly what goes in q/select, update_entities, etc.

`get_me`

Returns information about the currently authenticated user. Parameters — None. Returns — fibery/id, user/name, user/email, fibery/role, fibery/admin?. Example output

{
  "fibery/admin?": true,
  "user/email": "michael@fibery.io",
  "fibery/role": "role/admin",
  "fibery/id": "0000000",
  "user/name": "Michael Dubakov"
}

Querying & Searching

`query`

Executes a Fibery Query API command against any database. Supports field selection, filtering, sorting, pagination, sub-queries, and aggregation. Parameters

Name	Type	Required	Description
`query`	object	Yes	Query definition (see below)
`params`	object	No	Parameter values referenced in `q/where` via `$param` syntax. Default: `\{\}`

query object fields

Field	Type	Required	Description
`q/from`	string	Yes	Source database, e.g. `"SoftDev/bug"`
`q/select`	object \| string[]	Yes	Fields to retrieve
`q/where`	array	No	Filter expression
`q/order-by`	array	No	Sort criteria
`q/limit`	number	No	Results per page. Default: `100`. Max: `1000`
`q/offset`	number	No	Results to skip for pagination. Default: `0`

Field selection — basic

{
  "Name": "user/name"
}

Field selection — related entity field

{
  "OwnerName": [
    "user/Owner",
    "user/name"
  ]
}

Field selection — sub-query (q/limit is required)

{
  "Assignees": {
    "q/from": "assignments/assignees",
    "q/select": {
      "Who": "user/name"
    },
    "q/limit": 10
  }
}

Field selection — aggregation

{
  "TotalBugs": [
    "q/count",
    "fibery/id"
  ]
}

Available aggregate functions: q/count, q/sum, q/avg, q/min, q/max. q/sum/q/avg/q/min/q/max require a numeric sub-field: ["q/sum", ["Related Field", "Number Field"]]. Filter operators by field type

Field type	Operators
Number, Date	`=`, `!=`, `<`, `<=`, `>`, `>=`, `q/null?`
Text	`q/equals-ignoring-case?`, `q/not-equals-ignoring-case?`, `q/contains`, `q/not-contains`, `q/starts-with-ignoring-case?`, `q/ends-with-ignoring-case?`, `q/null-or-empty?`
Boolean / null check	`["=", ["q/null?", ["FieldPath"]], "$boolParam"]`
Reference	`q/in`, `q/not-in`, `q/count`
Date-range start/end	`["q/start", ["FieldPath"]]`, `["q/end", ["FieldPath"]]`
Location	`["q/address", ["FieldPath"]]` — parses to string, then use text operators

Filter combinators q/and and q/or take multiple filter clauses as operands:

["q/and", ["=", ["State"], "$state"], [">", ["Priority"], "$min"]]

Constraint — All filter values in q/where must use $param references. Inline literals will cause an error. Constraint — q/limit is required in every sub-query. Example — bugs currently In Progress with assignees

{
  "query": {
    "q/from": "SoftDev/bug",
    "q/select": {
      "Name": [
        "user/name"
      ],
      "Status": [
        "workflow/state",
        "enum/name"
      ],
      "PublicId": [
        "fibery/public-id"
      ],
      "Urgent": [
        "user/urgent"
      ],
      "Assignees": {
        "q/from": "assignments/assignees",
        "q/select": {
          "Who": "user/name"
        },
        "q/limit": 10
      }
    },
    "q/where": [
      "q/equals-ignoring-case?",
      [
        "workflow/state",
        "enum/name"
      ],
      "$status"
    ],
    "q/order-by": [
      [
        [
          "fibery/creation-date"
        ],
        "q/desc"
      ]
    ],
    "q/limit": 20
  },
  "params": {
    "$status": "In Progress"
  }
}

Example output

[
  {
    "Name": "Inline comment icons shift to a wrong position",
    "Status": "In Progress",
    "PublicId": "13959",
    "Urgent": false,
    "Assignees": [
      {
        "Who": "Nastya Karabitskaya"
      }
    ]
  }
]

Example — count all bugs

{
  "query": {
    "q/from": "SoftDev/bug",
    "q/select": [
      "q/count",
      "fibery/id"
    ]
  }
}

Example — recent features with owner and planned dates

{
  "query": {
    "q/from": "Product Management/feature",
    "q/select": {
      "Name": [
        "Product Management/name"
      ],
      "Status": [
        "workflow/state",
        "enum/name"
      ],
      "Owner": [
        "Product Management/owner",
        "user/name"
      ],
      "PlannedDates": [
        "Product Management/planned-dates"
      ]
    },
    "q/order-by": [
      [
        [
          "fibery/creation-date"
        ],
        "q/desc"
      ]
    ],
    "q/limit": 5
  }
}

Example output

[
  {
    "Name": "Handle Large Datasets in Tables",
    "Status": "Icebox",
    "Owner": "Victor Zhuk",
    "PlannedDates": null
  },
  {
