Authorizations

Authorization

string

header

required

OAuth2 client-credentials flow against the Dealroom Auth0 tenant. Use the client_id / client_secret from a Programmatic API key. Tokens are valid for 24h — Swagger UI will reuse the same token across operations. Revoking or deactivating a key rejects it on the next request (within a ≤5-minute server-side cache window), not at token expiry.

Headers

API-Version

string<date>

Pin a Stripe-style date-based API version (YYYY-MM-DD). Omit to use the latest version (2026-10-09). A pinned version is supported for 30 days after it is superseded, after which it returns 400.

Example:

"2026-10-09"

Path Parameters

string<uuid>

required

Stable UUID of the entity. Numeric ids are not accepted.

Minimum string length: 1

Example:

"345d1ab6-33df-4759-9e17-0d0c0ec9ab1c"

Query Parameters

filter

string

Filter expression for investors using nested syntax.

Examples:

Single: total_invested[gte]:1000000
AND: and(total_invested[gte]:1000000,hq_location[eq]:233)
OR: or(investor_type[eq]:venture_capital,investor_type[eq]:private_equity)

Operators: eq, neq, gt, gte, lt, lte, in_any, nin_any in_all / nin_all are available on repeated related-record filters and on the classification / roles flag sets. Default ref: 'entity' (can be omitted for entity filters)

Example:

"and(total_invested[gte]:1000000,hq_location[eq]:233)"

limit

integer<int32>

default:25

Number of results to return (1-500, default 25)

Required range: 1 <= x <= 500

Example:

25

cursor

string

Opaque cursor token from a previous response's page.next_cursor or page.prev_cursor. Round-trip it as-is — do not decode or modify.

Example:

"eyJ2IjoxLCJkIjoibmV4dCJ9"

sort

string

Sort by one or more keys. Prefix with - for descending order; comma-separated for multi-key sorts.

Pattern: ^(?:-?\w+)?(?:,(?:-?\w+)?)*$

Example:

"-investments_count"

include_total

boolean

Pass true to compute page.total (the matching record count). By default no count query runs and page.total is null.

Example:

true

currency

string

ISO 4217 currency code for monetary field conversion. Defaults to USD.

Example:

"EUR"

view

enum<string>

default:full

Which row shape to return, echoed as view in the response. full is the complete row, priced as a full record. summary drops the full-only blocks (founders, revenue, traffic, patents, alumni, founded_companies, career, education, portfolio, exits, match, rank) and is priced as a summary record.

Available options:

full,

summary

Example:
