Resolve a batch of email addresses to enriched contact records — the same identity data as GET /api/v1/lookup, but up to 1000 emails per call. Each email is normalized and SHA-256 hashed before lookup.
Filtering and billing. Provide an optional filter (same grammar as the lookup endpoint) to receive only records that match; non-matching records are dropped from the response and are not billed. Billing is on egress as contact_record — only records that carry a business email are billed, so a filtered-out or non-resolving email costs nothing. To receive and be billed for only records with a current business email, set filter to current_business_email:ne:"".
Pagination. page_size (default 100, max 1000) bounds the page; a non-empty cursor in the response means more records remain — pass it back to fetch the next page.
