Reinstate a specific tombstoned agent version
const url = 'https://example.com/v1/agents/example/versions/example/reinstate';const options = {method: 'POST', headers: {Authorization: 'Bearer <token>'}};
try { const response = await fetch(url, options); const data = await response.json(); console.log(data);} catch (error) { console.error(error);}curl --request POST \ --url https://example.com/v1/agents/example/versions/example/reinstate \ --header 'Authorization: Bearer <token>'Un-tombstones a previously-unregistered version: clears the tombstone on that version and recomputes the highest active version, which numbers the next one. Restores the manifest bytes verbatim (semver hygiene: reinstate never mutates). Idempotent — reinstating an active version is a no-op (returns wasTombstoned: false). Reinstating any version of a fully-retired agent reactivates the identity: subsequent GETs return 200, invocations succeed. Publish is always allowed regardless of retirement state — this verb is for restoring previously-unregistered bytes, not for reactivating a retired identity (a fresh publish does that).

Section titled “Parameters”Path Parameters
Section titled “Path Parameters”AgentId — dotted namespace (acme.drafting).
Semver of the agent version.
Header Parameters
Section titled “Header Parameters”Caller-supplied idempotency key, scoped to the caller: the same key from someone else in the workspace is their own request (from 0.1.5). Retries with the same key return the original response byte-identical (per docs/API-ROUTE-CONVENTIONS.md §3.1). A retry sent while the first request still runs is answered 409 idempotency-key-in-flight with Retry-After, on a runtime whose store holds keys (from 0.1.5); retry after it, and you get the first request’s answer. An answer that carries a secret (a new API key or public run token, a session token, a generated signing secret) isn’t kept: a retry gets 409 idempotency-key-replay-withheld, with the first request’s status and when it succeeded (from 0.1.5). A request whose key store can’t be read before it runs is answered 503 idempotency-store-unavailable with Retry-After: nothing ran, so retry with the same key (from 0.3.0).
Responses
Section titled “Responses”Reinstated.

true when this call un-tombstoned the version; false when it was already active (idempotent no-op).
