Koyfin vs Brazil CVM Filings API
Koyfin vs CVM filings API compares a research workspace to a filings HTTP API. Koyfin is built for charts, screening, and fundamental workflows in a UI. apicvm is built for developers who need programmatic DFP/ITR/FRE access. Complementary — never "replace Koyfin".
Side-by-side
| Capability | Koyfin | apicvm |
|---|---|---|
| Interactive research UI | Core product | No (docs + API) |
| CVM PDF download by document UUID | Not the product shape | Yes |
| Agent / pipeline HTTP tools | Limited / different shape | Yes |
| Async page markdown extraction | No | Yes (Pro) |
Developer shape
curl -H "Authorization: Bearer $APICVM_KEY" \
"$APICVM_URL/v1/documents?ticker=EGIE3&type=FRE&year=2024&perPage=20"Use Koyfin (or Bloomberg/Morningstar) for interactive research; use apicvm when you need filings in code. See Bloomberg vs filings API.
When apicvm is the better fit
- Automating Brazil filing archives
- Tool-calling agents that must cite CVM document IDs
- Building internal coverage dashboards on raw filings metadata
When Koyfin is the better fit
- Interactive equity research and charting
- Teams that do not need PDF automation
- Multi-asset workspace workflows beyond Brazil filings
Current limitations
- apicvm is not a terminal UI
- We do not document Koyfin's Brazil data entitlements
- Filings inventory follows ingestion, not UI refresh cycles
