Scoped to the caller-subject (WHERE node_id = $1 and user_id = subject); a node that does not exist or belongs to another user returns 404 node_not_found (existence cannot be probed). Up to the 200 strongest edges touching the node are returned, each with the neighbour’s raw id and the direction relative to this node.

Authorization

This route requires the read scope. A missing or invalid credential returns 401 authentication_error. A valid credential without the scope returns 403 permission_denied, and the problem body names the exact scope required.

Headers

These are request conventions the contract does not declare as parameters, so they do not appear in the schema tables below.

Header	Applies	What it does
`X-Exo-API-Key`	Required	Your Exo API key, `exo_<env>_<token>`. `Authorization: Bearer exo_...` is accepted as an alternate.
`X-Exo-Subject`	Optional	Acts for a provisioned subject instead of the key owner. An unprovisioned id returns 403 `subject_not_provisioned`.
`Idempotency-Key`	Not applicable	The replay engine covers POST requests only.
`X-Request-Id`	Response	Returned on every response, including `204`s. Quote it in a support request.

Success responses

Status	Meaning
`200`	Successful Response

Errors

Status	Code	When
`400`	`invalid_request`	Malformed request, for example an invalid cursor.
`401`	`authentication_error`	Missing or invalid credentials.
`403`	`permission_denied`	Missing scope, or an unprovisioned subject selector.
`404`	`not_found`	The resource does not exist, or is not visible to this caller.
`409`	`conflict`	A conflict with the current state of the resource.
`422`	`validation_error`	The request was understood but failed field validation.
`429`	`rate_limit_exceeded`	Rate limit exceeded. Retry after the Retry-After interval.
`503`	`service_degraded`	A dependency is temporarily unavailable. Safe to retry.

Beyond the shared statuses, this route can answer with node_not_found. Every problem body names its own code, and the type URI always resolves to the matching page. Every error is an RFC 9457 application/problem+json body carrying a stable code, a requestId, and a suggestedAction where Exo has one. See Errors.
