Workspace API

Accounts

Save and annotate the global accounts you care about. Search returns only the ones you have saved to your workspace.

You save global Parcel accounts to your workspace and annotate them with your own data. Workspace account search returns only the accounts you have saved, not the full global dataset. To start tracking a new account, find it via the Data API and then upsert it by domain or id.

Fields you set

These fields are written by your team via the upsert endpoint.

Field	Type	Notes
`icp_tier`	`string \| null`	Your ICP classification for this account. One of `tier_1`, `tier_2`, `tier_3`, `disqualified`, or `null` (unset). Setting this field schedules an Atlas recompute.
`workspace_status`	`string \| null`	Your workflow state for this account (for example, `"active"`, `"churned"`). Any string value or `null`.
`notes`	`string \| null`	Free-text notes for your team. Explicit `null` clears the value.
`tags`	`string[]`	Arbitrary labels. Full-replace on every write (sending `["boston"]` replaces the entire tag set).

Fields Parcel computes (read-only)

These fields are computed by Parcel based on market signals. You cannot set them directly.

Field	Type	Notes
`atlas_score`	`integer \| null`	Atlas activity score, 0 to 100. Higher scores indicate more recent and more significant pipeline activity. `null` until enough signal data is available.
`atlas_trend`	`string \| null`	Direction of recent Atlas score movement: `"up"`, `"down"`, or `"flat"`. `null` until a trend can be established.

Setting icp_tier on an account schedules a fresh Atlas recompute so that your tier assignment is reflected in a subsequent atlas_score.

Filters

Default sort: updated_at desc

Filter key	Type	Notes
`icp_tier`	field	One of `tier_1`, `tier_2`, `tier_3`, `disqualified`. Array value = OR.
`workspace_status`	field	Your workflow status string. Exact match.
`tags`	field	Tag value. Array value = OR.
`name`	field	Organization name. Supports fuzzy match.
`city`	field	City name. `exact_match: false` (default) = fuzzy.
`state`	field	State code, for example `"MA"`.
`account_type`	field	Matches against `account_types[]`. Array value = OR.

Sort keys: updated_at, atlas_score, name, created_at

Range keys: atlas_score

icp_tier and account_type are enum-backed: a value outside the allowed set returns 400 (not zero rows), and they do not accept exact_match since a closed vocabulary is always exact. See Errors.

Relational filters

Use relational filters to match accounts based on properties of their related records.

Key	Inner filter fields
`has_project`	`stage`, `primary_use`, `city`, `name`, `residential_units` (range)
`without_project`	`stage`, `primary_use`, `city`, `name`, `residential_units` (range)
`has_signal`	`signal_type`, `filed_at` (range)
`without_signal`	`signal_type`, `filed_at` (range)
`has_contact`	`title`, `name`
`without_contact`	`title`, `name`

Each without_* key takes the same inner fields as its has_* twin, but matches your saved accounts with NO related record satisfying the inner criteria (NOT EXISTS) instead of at least one. See Filtering for the semantics.

Includes

Valid include keys for GET /workspace/accounts/{id}: projects, contacts, signals.

Example: GET /workspace/accounts/<id>?include=projects&include=signals

Search example

The query below finds your tier 1 accounts that have a permit_filed signal in the last 90 days, sorted by Atlas score descending.

The data array is trimmed to one record above. A page returning 4 accounts costs 4 credits (1 per row returned).
