Use the linked-institution/search endpoint to search for financial institutions by name through a provider, in order to power an institution picker / search UI. Supply the provider, the productId, and the vendorServices you intend to use the institution for; results are filtered to institutions that support those services. The account_verification_with_match service filters the same institutions as account_verification, because any institution that supports account verification also supports the identity match. Such an institution lists account_verification in supportedServices.

Each result includes the providerId (unique institution identifier for the provider, useful for deduping), institutionName, an optional institutionLogo, and the supportedServices the institution supports. The raw provider payload is nested under providerDetails. No provider credentials are exposed.
