Authenticate with an API key using the Authorization header: `Bearer brz_...` servers: - url: https://api.breezing.io/v1 security: - BearerAuth: [] paths: /transactions/update-price-auto: post: tags: - Transactions summary: Update token prices automatically description: >- Recompute fiat amounts for a set of transactions by fetching historical prices, the API equivalent of the dashboard "Update Token Price" automatic mode. The selected transactions (and the paired leg of any exchange trade) are flagged for repricing and a background job fetches the price for each token at each transaction date from the chosen source, then backfills amountFiat (and feeFiat where the fee token matches). This is asynchronous: the response returns a taskId. Poll GET /tasks to monitor progress, then GET /transactions to see the updated fiat amounts. NGL is not recalculated automatically; call POST /ngl/calculate when ready. Returns 404 if any transaction is not found, 409 if any is locked or processing, and 409 TASK_IN_PROGRESS if an automatic price update is already running for this company (concurrent runs share one pricing queue and could corrupt computed prices).
