Usage Notes

  • Exchange IDs map to protocol implementations, not individual pool addresses. Use these identifiers when filtering by exchange_id in reserves and pricing endpoints.
  • Status reflects current coverage as documented in the Data Catalog Coverage page.
  • Additional protocols may be added over time; clients should gracefully handle unknown exchange IDs.
