## Query parameters

- **`integrated_account_id`** _(string, required)_
  The ID of the integrated account to use for the request.
- **`truto_response_format`** _(string)_
  The format of the response. - `unified` returns the response with unified mappings applied. - `raw` returns the unprocessed, raw response from the remote API. - `normalized` applies the unified mappings and returns the data in a normalized format. - `stream` returns the response as a stream, which is ideal for transmitting large datasets, files, or binary data. Using streaming mode helps to efficiently handle large payloads or real-time data flows without requiring the entire data to be buffered in memory. - `debug` returns the final unified result alongside raw remote fetch information. The response is an envelope containing `result` (identical to unified mode output) and `debug` (with `requestUrl`, `requestOptions`, `data`, `responseHeaders`, and for list operations: `nextCursor`, `isLooping`, `isEmptyResult`, `resultCount`). When the upstream body exceeds 1 MiB, `data` is replaced by `{ truto_truncated: true, truto_max_bytes, truto_excerpt }`. `debug` is `null` for static responses or when `truto_skip_api_call=true`. Defaults to `unified`.
  Allowed: `unified`, `raw`, `normalized`, `stream`, `debug`
- **`truto_key_by`** _(string)_
  By default the `result` attribute is an array of objects. This parameter allows you to specify a field in each `result` objects to use as key, which transforms the `result` array into an object with the array items keyed by the field. This is useful for when you want to use the result as a lookup table.
- **`truto_ignore_limit`** _(boolean)_
  Ignores the `limit` query parameter.
- **`truto_ignore_remote_data`** _(boolean)_
  Excludes the `remote_data` attribute from the response.
- **`truto_exclude_fields`** _(array<string>)_
  Array of fields to exclude from the response.
- **`remote_query`** _(object)_
  Query parameters to pass to the underlying API without any transformations. Refer [this guide](https://truto.one/docs/api-reference/overview/querying#remote-query-parameters) to see how to structure the query parameters.
- **`region`** _(string)_
  AWS region to read. Lambda is regional; one call reads one region.

## Response body

- **`result`** _(array<object>)_
  List of Serverless functions
  - **`id`** _(string, required)_
    Truto's stable unified identifier for this object. Opaque; use provider_id to address the object in the provider's own console or API.
  - **`provider_id`** _(string)_
    The provider's own identifier, passed through verbatim — a full ARN, resource id, or self-link. Never truncated, prefixed, or normalized.
  - **`provider`** _(string)_
    Which cloud this object was read from.
    Allowed: `aws`, `azure`, `gcp`
  - **`account`** _(string)_
    The account, subscription or project this object belongs to.
  - **`region`** _(string)_
    Where the object is located. 'global' denotes genuinely global resources (e.g. IAM, GCP VPC networks) rather than a guessed region. A substituted region (when none is derivable) is flagged in unreadable_fields.
  - **`native_type`** _(string)_
    The provider's own type string, unmodified — for example 'AWS::S3::Bucket', 'aws_iam_role', 'Microsoft.Sql/servers'. Used for display and drill-down.
  - **`tags`** _(object)_
    Key-value pairs exactly as the customer set them: no case folding, key/value normalization, or merging of separate provider concepts. An empty object means no tags; tags that could not be read appear in unreadable_fields instead.
  - **`collected_at`** _(string)_
    When Truto actually read this object from the provider, in UTC ISO 8601 with the offset present — not the request time, and not a provider timestamp.
  - **`updated_at`** _(string)_
    When the object was last modified at the provider, in UTC ISO 8601. Null when the provider does not record one - see unreadable_fields.
  - **`created_at`** _(string)_
    When the object was created at the provider, in UTC ISO 8601. Null when the provider does not record one - see unreadable_fields.
  - **`unreadable_fields`** _(array<object>)_
    Fields on this object that could not be read, and why. An empty array means everything was read. Use this to tell a real value from a missing one.
    - **`field`** _(string)_
      The property on this resource that could not be read.
    - **`reason`** _(string)_
      Why the field could not be read. available_on_get: Not read on list to keep the list fast; call GET for this resource's id to get it.
      Allowed: `not_supported_by_provider`, `not_configured`, `permission_denied`, `not_collected`, `collection_error`, `partially_collected`, `available_on_get`
    - **`detail`** _(string)_
      Explanation of the reason, where one adds anything.
  - **`remote_data`** _(object)_
    Raw data returned from the remote API call.
  - **`name`** _(string)_
    The function's name, verbatim.
  - **`runtime`** _(string)_
    The language runtime identifier, verbatim (nodejs22.x, python3.12). Null for a container-image function, which has no managed runtime.
  - **`handler`** _(string)_
    The entry point the platform calls. Null for a container-image function.
  - **`package_type`** _(string)_
    How the code is packaged: a zip archive or a container image. The provider's own value is in remote_data.
    Allowed: `archive`, `container_image`, `unknown`
  - **`memory_mb`** _(integer)_
    Memory available to the function, in MB.
  - **`timeout_seconds`** _(integer)_
    How long one invocation may run before it is stopped.
  - **`architectures`** _(array<string>)_
    Instruction set architectures, verbatim (x86_64, arm64).
  - **`execution_role`** _(object)_
    The identity the function runs as (on AWS the execution role).
    - **`id`** _(string)_
      The target's `id`.
  - **`environment_variable_names`** _(array<string>)_
    Names of the environment variables set on the function. Values are never read into this row or into remote_data, because they often hold credentials.
  - **`encryption_key`** _(object)_
    The customer managed key that encrypts the function's environment variables. Null when the provider's default key is used.
    - **`id`** _(string)_
      The target's `id`.
  - **`network_boundary`** _(object)_
    The VPC / virtual network the function is attached to. Null when it runs on the provider network with no VPC attachment.
    - **`id`** _(string)_
      The target's `id`.
  - **`subnet_ids`** _(array<string>)_
    Subnets of the VPC attachment. Empty with no VPC attachment.
  - **`attached_rule_sets`** _(array<object>)_
    Security groups of the VPC attachment.
    - **`id`** _(string)_
      The target's `id`.
  - **`tracing_enabled`** _(boolean)_
    Whether active request tracing is on (on AWS, X-Ray Active mode).
  - **`dead_letter_target_id`** _(string)_
    Where failed asynchronous invocations go (an SQS queue or SNS topic ARN on AWS). Null when none is set.
  - **`layers`** _(array<string>)_
    Layer ARNs attached to the function.
  - **`log_destination`** _(object)_
    The log group the function writes to (on AWS the CloudWatch Logs group from its logging configuration, by default /aws/lambda/<name>). The provider creates it on the first invocation, so this can name a log group that does not exist yet.
    - **`id`** _(string)_
      The target's `id`.
  - **`state`** _(string)_
    Lifecycle state, normalised. pending: being created or having resources set up; active: ready to invoke; inactive: idle long enough that the provider reclaimed its resources (the next invocation re-activates it); failed: creation or a resource update failed. Read on GET (on AWS the list does not return it). The provider's own value is in remote_data.
    Allowed: `pending`, `active`, `inactive`, `failed`, `unknown`
  - **`code_sha256`** _(string)_
    Hash of the deployment package, as the provider reports it.
- **`next_cursor`** _(string)_
  The cursor to use for the next page of results. Pass this value as `next_cursor` in the query parameter in the next request to get the next page of results.
- **`debug`** _(object)_
  Present only when `truto_response_format=debug`. Contains raw fetch details: `requestUrl`, `requestOptions`, `data`, `responseHeaders`, `nextCursor`, `isLooping`, `isEmptyResult`, `resultCount`. `data` is the parsed upstream body; when its JSON form exceeds 1 MiB it is replaced by `{ truto_truncated: true, truto_max_bytes, truto_excerpt }`, where `truto_excerpt` is the leading bytes of that body. The same applies to a string `requestOptions.body`. `null` for static responses or when `truto_skip_api_call=true`.
  - **`requestUrl`** _(string)_
  - **`requestOptions`** _(object)_
  - **`data`** _(unknown)_
  - **`responseHeaders`** _(object)_
  - **`nextCursor`** _(string)_
  - **`isLooping`** _(boolean)_
  - **`isEmptyResult`** _(boolean)_
  - **`resultCount`** _(number)_
