Live feeds

Marking feed IDs are stable, lowercase identifiers such as:

btc-usd
eth-usd
sol-usd

Use the catalog endpoint to discover the current offered products:

curl https://api.marking.fyi/v1/feeds

Use feed status to combine manifest, health, and latest signed state:

curl https://api.marking.fyi/v1/feed-status

Each feed includes:

  • canonical feed ID;
  • display name and unit;
  • eligible source policy;
  • minimum source/quorum boundary;
  • aggregation policy;
  • delivery capabilities.

Latest update​

curl https://api.marking.fyi/v1/feeds/eth-usd/latest

Canonical updates include source timestamps, Marking receive/normalize/canonicalize/sign timestamps, source quorum metadata, excluded-source reasons, and a feed-local sequence.

History​

curl "https://api.marking.fyi/v1/feeds/eth-usd/history?limit=100"

History returns signed canonical updates. Consumers should still verify each envelope and apply freshness rules appropriate to their use case.
