}Authorizations
Your HayInsights API key (prefixed apk_). Create and manage keys in the
HayInsights dashboard (Account → API keys).
Send it in the X-API-Key header on every request to /openapi/v1/*.
Which data domains you may access and your request quota are both governed by
the subscription plan attached to the key — see the Plans & features and
Rate limits guides.
Path Parameters
Exchange ticker for the ETF (e.g. a TSE code like 1306).
"1306"
Response
Constituent holdings of the ETF.
Standard success envelope shared by every endpoint. Each operation's response
wrapper extends this (via allOf) and adds a typed data property.
Always true for a successful response.
true
Mirrors the HTTP status code.
