By AWS service
Cost distribution for the current month across the AWS services that run the pipeline. The AI layer (models available via Bedrock) usually dominates; Lambda, DynamoDB and CloudFront are a low and stable baseline.

Daily variation
Daily cost in BRL over the last 30 days. Spikes on backfill days (historical processing for new cities) are expected.
How we measure
A scheduled Lambda (FiscalCustos) runs daily at 03:00 BRT, queries AWS Cost Explorer with daily granularity grouped by service, persists to a dedicated DynamoDB table, and the site reads from there.
USD→BRL conversion uses the Brazilian Central Bank PTAX selling rate (SGS series 1) for the day. The factor is recorded together with the snapshot — auditable after the fact.
FiscalCustos itself costs about USD 0.30/month to run (Cost Explorer charges USD 0.01 per call).
