Brazilian Equities Data API
Situation
Other systems needed dependable Brazilian equities data without leaning on flaky third-party wrappers.
What mattered
- Prefer official exchange files as the source of truth
- API must be documented for other teams to integrate
- Monitoring before the first external consumer
- Clear view of lag and failures when ingest slips
Problem
Reliable Brazilian market data is locked behind expensive terminals and inconsistent vendor feeds.
Approach
We built a data platform that takes official exchange files, normalizes them, and exposes a clean documented API other systems can trust, with monitoring from day one.
What we delivered
A service that pulls official files, stores a clean dataset, and serves it through a documented API. Latency, lag, and errors are visible early so problems show up before clients do.
Outcome
Official exchange files become a documented API, with metrics and alerts wired from the start.
