content triggers a Voyage re-embed and collapses the node to one fresh chunk (multi-chunk re-segmentation stays the ingest pipeline’s job). metadata merges into the frontmatter; title replaces the title. A node not owned by the effective subject is 404.

Authorization

This route requires the graph:write scope. A key carrying memory:forget or write also qualifies. 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.

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.

Notes

Editing content re-embeds the node and collapses it to one fresh chunk. Re-segmenting into several chunks stays the ingest pipeline’s job.
metadata merges, title replaces. Send only what you want to change.

Authorizations

X-Exo-API-Key

string

header

required

An Exo API key (exo_...) sent as the X-Exo-API-Key header.

Path Parameters

node_id

string

required

The knowledge-graph node id.

Body

application/json

Body for PATCH /v1/graph/nodes/{id}. Every field is optional; a request that sets content triggers a Voyage re-embed, metadata merges into the node frontmatter, title replaces the display title.

content

Maximum string length: 100000

metadata

title

string | null

Maximum string length: 2000

Response

Successful Response

A knowledge-graph node as it stands after a mutation.

Returned by PATCH /v1/graph/nodes/{id}. updatedAt is the moment the edit was applied; authorityLevel is the node's influence on retrieval.
