GEThttps://forumulate.com/api/delivery/v1/libraries/{libraryId}/routes/resolve

What a catch-all page renders at path: {kind: "entry", route, entry} with the entry populated to depth; else {kind: "redirect", to, status} when a redirect rule matches; else 404. A live route wins over a redirect, and a rewrite rule serves its target’s route at the path asked for. The route and its entry are each served like a one-entry read in locale: the chain’s first twin, non-localized fields from the source, empty localized fields from the chain.

Parameters
localestringquery
A locale code (the library’s source locale when omitted). * on a one-entry or global read returns every locale under localized.
fallbackbooleanquery
Fall back through the declared locale chain, then the source (default true). Whole entry: a locale with no twin serves the first twin of its chain. Per field: an empty localized field — and an empty localized leaf inside a localized group, array or blocks row, matched by row id — is filled from the first entry of the chain that has it. Non-localized fields always come from the source entry. false: only the asked locale, empty fields left empty.
depthintegerquery
How far references are populated: 0 serves stubs {kind, id, contentType, slug}. Default 1; capped by the plan’s reference depth (a larger value is a 422).
populatestringquery
Per type, the fields to keep on a populated entry: populate[author]=name,avatar.
selectstringquery
Comma-separated field paths to keep in fields.
draftbooleanquery
Accepted for a preview key, which always reads drafts; a delivery key asking for drafts is a 403.
pathstringqueryrequired
The site path, e.g. /pricing (a full URL is accepted; only its path is read).
forumulate-versionstringheader
API version negotiation. Send forumulate-version: 2026-12-01 on every request from a new integration; it is optional only so that integrations written before versioning keep working. Each version includes everything before it:
libraryIdstringpathrequired
Path parameter.

403 Authenticated, and not allowed — always rbac.forbidden, whether what is missing is the capability, the token scope, or a resource the token is pinned away from. The message names the capability and, for a scope refusal, the scopes that would grant it. A refusal because of the PLAN is a 402 with quota.exceeded, not this.
