Deprecation and Link response headers. The earlier combined claim-write route is retired; use the matching focused claim route.
Route replacements
Token browsing now uses self-contained sort values:
newest, oldest, trending, liquidity, market_cap, or volume_24h. Do not send a separate order parameter.

No sunset date is currently announced. Integrations should migrate to the focused routes so unsupported parameter combinations cannot be constructed.
