Macro data · point-in-time first

Stop backtesting on revised prints.

Economic series get revised. Pulling “today’s value” without a vintage date cites a number that was never actually published. vintage-api.com serves vintage-aware macro snapshots: what was knowable as of a date, so your macro layer isn’t a time machine.

Primary

PIT Print Vault

Point-in-time / vintage observations for macro series. Ask what was knowable as of a date; keep first release vs later revisions visible.

  • As-of snapshots instead of silent overwrite
  • First vs revised prints kept distinct
  • Designed for backtests that must not look ahead
Second card

Issuer Taxonomy

ISIN → issuer industry and region with provenance via open schemes (SIC / NAICS / NACE / Wikidata), not GICS.

  • Identifier resolve without a GICS seat
  • Honest scheme labels, no fake GICS parity
  • Same request-access path as PIT
Access model. Public site is docs and request-access today. Live multi-tenant API keys and a unified production gateway are issued to approved callers after card charge. We don’t pretend the open internet already has unlimited production traffic. Issuer Taxonomy is not a GICS substitute or license workaround.
