Read a family

Send the key as Authorization: Bearer <key>. Two kinds of key exist.

Organization keys are issued in the portal (Settings, then API keys), each bound to one environment, shaped nx_<environment slug>_<64 hex>. They carry no capabilities and pass every capability check, with one exception: routes under /api/v1/records, /api/v1/engines/{id}/opportunities, /api/v1/graph and /api/v1/catalog/documents accept an organization key only when its environment is live, and refuse any other with 403 scoped_key_required. Revocation takes effect within 60 seconds.

Scoped keys are issued by Nexio on request, shaped nxsk_v1_<24 hex key id>_<43 character secret>. Each is bound to one org, one environment, a set of engines and a set of capabilities. A malformed, unknown or revoked nxsk_ key fails with 401 and is never retried as an organization key. Revocation takes effect on the next request. A scoped key without a route's capability gets 403 insufficient_capability; a scoped key not bound to the engine gets 403 engine_binding_forbidden.

Key-grantable capabilities: engines:read, runs:write, runs:read, runs:defensibility:read, runs:test, catalog:read, catalog:documents:read, webhooks:manage, conversations:use, conversations:export, records:read, records:opportunities:run, actions:write, actions:read, graph:read, records:analyze.

Routes that accept organization keys only (every scoped key gets 403 insufficient_capability): environment management, engine create, update, configuration and publish, and conversation instance authoring. Each operation description names the capability a scoped key needs.

The person the request is for, as your identity provider's stable user id. Narrows what the key reaches; never widens it. Send it on every request; under the shadow and lit postures a read without it answers 403 identity_unmapped.

The acting person's verified sign-in email. The seat is derived from it.

Signed assertion v1.<unix seconds>.<hex HMAC-SHA256> over acting_principal|acting_email|reserved|timestamp (each part trimmed, the email lowercased). The third field is reserved: send an empty string. The timestamp must be within 5 minutes of the server clock, either way. Checked once Nexio enables assertion verification for your organization, when it provisions the signing secret; a missing or wrong assertion then answers 403 assertion_invalid and one outside the window 403 assertion_stale.

principal:<id>: a read-only view of another person's data, honored only for a caller whose own scope is All or Platform and ignored for anyone else. For such a caller, a value that is not principal:<id>, or names nobody, answers 400 lens_target_unknown.

Plane name, for example book or rawams_claims.

Family name, for example policies or claim.

The system-of-record connection to read. Optional when the organization has exactly one qualifying connection; required when it has several (otherwise 400 book_connection_ambiguous).

One policy key. Policy-grain families only; on any other family, or when the key does not decode, the answer is 400 invalid_request.

One client key (the system of record's top-level record key; starts with bk1_). Client-grain families only; on any other family, or when the key does not decode, the answer is 400 invalid_request.

Rows per page, a positive integer. Defaults to 50; values above 10,000 are clamped to 10,000.

The page.next_cursor from the previous page. It carries the filters: a cursor sent with policy_key or client_key answers 400 cursor_filter_mismatch, and a cursor that does not decode answers 400 invalid_cursor.
