API Reference
Base URL
https://registry.siros.org/api/v1
GET /schemas
Returns all registered attestation schemas as unsigned JSON (or JWS compact serialization when signing is enabled).
curl https://registry.siros.org/api/v1/schemas.jsonThe response contains a data array of SchemaMeta objects,
plus total, limit, and offset fields.
GET /schemas/{schemaId}
Returns a single SchemaMeta object by UUID.
curl https://registry.siros.org/api/v1/schemas/{uuid}.jsonGET /orgs (SIROS extension — not part of TS11)
Not part of TS11 — the ETSI spec has no "organization" concept. Returns an index of the organizations contributing to this registry, each with a link to its organization-scoped schema list.
curl https://registry.siros.org/api/v1/orgs.jsonGET /orgs/{org}/schemas (SIROS extension — not part of TS11)
Also not part of TS11. Returns the same shape as GET /schemas, filtered to
TS11-compliant schemas contributed by one organization. Each schema object is identical to
the one returned by the global list — filtering happens by which resource you request, not
by a new field on SchemaMeta, so this has no effect on TS11 conformance.
curl https://registry.siros.org/api/v1/orgs/{org}/schemas.jsonTo filter to a set of organizations, fetch each organization's list separately and merge client-side — there's no static resource for an arbitrary combination of orgs.
GET /attributes
Returns the Catalogue of Attributes — a cross-cutting index of all claims defined across registered credentials (per TS11 §4.2).
curl https://registry.siros.org/api/v1/attributes.jsonThe response contains a data array of Attribute objects,
plus total, limit, and offset fields.
Supports query parameters:
| Parameter | Description |
|---|---|
limit | Maximum number of results (default: all) |
offset | Number of results to skip (default: 0) |
nameSpace | Filter by namespace URI |
identifier | Filter by attribute identifier (substring match) |
GET /attributes/{attrId}
Returns a single Attribute object by identifier.
curl https://registry.siros.org/api/v1/attributes/{identifier}.jsonSee the Catalogue of Attributes page for a browsable view.
Signature Verification
When signing is enabled, responses are also available as .jwt files
(JWS compact serialization). Public keys are published as a JWKS at
https://registry.siros.org/api/v1/.well-known/jwks.json.
