Field-level reference for the objects you'll see in tool results. *Exposure* says who can ever see the field through MCP or the web. ## Profile One per Seeker or Organization. Read with `get_profile`; written with `update_profile`. | Field | Type | Notes | Exposure | | ------------------------------- | --------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------- | | `id` | uuid | Stable profile ID (the `seeker_id` Organizations use). | Counterparties | | `type` | enum | `seeker` \| `organization`. Fixed at signup. | Counterparties | | `name` | text | Person or Organization name; 1–60 chars. | Counterparties + public web | | `tagline` | text? | Seeker only; ≤140 chars, short summary. | Counterparties + public web | | `description` | text? | Organization only; ≤6,000 chars. | Counterparties + public web | | `signup_email` | text | Sign-in, receipts. | Owner only — never via MCP or web | | `contact_email` | text? | The match-payoff address. | Owner; Organizations post-[unlock](/concepts/interest-and-matches#contact-unlocks); connected Seekers (free, both ways) | | `organization_domain` | text? | Organization only; derived from the website declared at signup, and the signup email must match it. Immutable — the trust anchor. | Counterparties | | `handle` | text | 3–30 chars, `a–z 0–9 -`. First-come, permanent. Public page at `/s/[handle]` (Seekers) or `/o/[handle]` (Organizations). | Public | | `website` | url? | Single [website link](/best-practices/profile); http(s), ≤140 chars. Optional for Seekers; required for Organizations and always on their verified `organization_domain`. | Counterparties + public web | | `created_at` / `last_edited_at` | timestamp | | Counterparties | ## Seeker content One per Seeker. Written with `update_experience` and `update_what_is_next`; the owner reads both back from `get_profile`, and Organizations and peer Seekers see both via `get_profile`. | Field | Type | Notes | Exposure | | -------------- | --------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------- | | `experience` | text? | ≤6,000 chars. Freeform prose — education, professional history, skillset. | Counterparties + public web | | `what_is_next` | text? | ≤6,000 chars. Freeform prose — the roles and Organizations you'd want next. Organizations and other Seekers see it over MCP; **never** on the public web page. | Counterparties + MCP, never public web | | `updated_at` | timestamp | | Counterparties + public web | Search over these blobs is plain keyword/text matching — no structured filters. ## Role Posted by Organizations; public while open. | Field | Type | Notes | | -------------------------- | --------- | --------------------------------------------------------------------------------- | | `id` | uuid | | | `organization_id` | uuid | Owning Organization profile. | | `name` | text | 1–60 chars. | | `description` | text | ≤6,000 chars. | | `what_we_are_looking_for` | text? | ≤6,000 chars. The ideal-Seeker blob. | | `location` | text? | ≤60 chars, free text. | | `model` | enum? | `distributed` \| `hybrid` \| `in-person`. | | `status` | enum | `open` \| `closed` \| `expired` — see [role lifecycle](/concepts/role-lifecycle). | | `posted_at` / `expires_at` | timestamp | Expiry is 30 days from posting. | Public role pages live at `/o/[org]/[role]`. ## Interest One row per `(seeker, role, side)` — unique, so interest is idempotent and per-side. | Field | Type | Notes | | ----------------------- | --------- | ---------------------------------------------- | | `id` | uuid | Returned as `interest_id` in lists. | | `seeker_id` / `role_id` | uuid | The pair. | | `side` | enum | `seeker` \| `organization` — who expressed it. | | `created_at` | timestamp | `interested_at` in lists. | ## Match Computed, never stored: both sides' interest rows exist for the same `(seeker, role)` **and** the role is open. | Field | Type | Notes | | ------------------------------------------- | --------- | --------------------------------------- | | `seeker_id` / `role_id` / `organization_id` | uuid | The matched pair and role owner. | | `matched_at` | timestamp | When the second side's interest landed. | ## Connection interest / Connection (Seeker ↔ Seeker) A directed `connection_interest` row per `(from_seeker, to_seeker)`. A **connection** is computed: both directions exist. On connection, both Seekers' `contact_email`s are shared **for free** — no credits, no unlock. | Field | Type | Notes | | --------------------------------- | --------- | ----------------------------------------------- | | `from_seeker_id` / `to_seeker_id` | uuid | The directed edge; `from ≠ to`. | | `created_at` | timestamp | | | `connected_seeker_id` | uuid | On a mutual connection (in `list_connections`). | Public Seeker profiles show a connection **count** (never identities). ## Unlock (Organization) | Field | Type | Notes | | ------------------------------- | --------- | ---------------------------------- | | `id` | uuid | | | `organization_id` / `seeker_id` | uuid | Unique pair — one lifetime unlock. | | `credits_spent` | integer | 1 (\$1). | | `unlocked_at` | timestamp | | ## Credits (Organization) | Field | Type | Notes | | --------- | ------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `balance` | integer | Credits (\$1 = 1 credit); `balance` in `get_credit_balance`. Never negative. Starts at 20 for a new Organization — the [Early Access welcome grant](/concepts/credits#starting-balance). | ## API key | Field | Type | Notes | | -------------- | --------- | ------------------------------------------------------------------------------ | | key | `ick_…` | Shown once at creation; only a hash is stored. Rotate/revoke in the dashboard. | | `last_used_at` | timestamp | Updated on every authenticated request; visible in the dashboard. |
