Returns project-wide attributed payouts for ingestion pipelines. Each result is one payout row
(referral commission and/or referee rebate) linked to an attribution. Pool payouts without
attribution_id are excluded.

Authentication:

• Requires API key with service_role scope in the Authorization header: Authorization: Bearer <api_key>
• The project is automatically derived from the API key's associated project

Pagination:

• limit controls how many payout rows are returned per request (default 500, max 1000)
• after_id is a cursor on payout_id
• count equals the number of payout rows in results

Incremental loads:

• created_since filters payouts with created_at > value
• updated_since filters payouts with updated_at > value, or any linked affiliate/referee claim check with updated_at > value
• payout_status reflects the full payout lifecycle (all statuses are exported; filter downstream in your warehouse)
• Periodic full backfills are recommended for long-running pipelines
