 ## Service metadata
 
-FilecoinWarmStorageService implements `IFilecoinServiceMetadata`, exposing a `name()` and `description()` for `eth_call`. Other FOC services are encouraged to use this interface so explorers and clients can identify service operator contracts without hard-coded address maps. Consumers should note that this output should be treated as untrusted data and should only ever be presented to users in carefully escaped form.
+FilecoinWarmStorageService implements `IFilecoinServiceMetadata`, exposing `name()`, `description()`, and `homepage()` for `eth_call`. Other FOC services are encouraged to use this interface so explorers and clients can identify service operator contracts without hard-coded address maps. `description()` is capped at 256 bytes and should be treated as untrusted display-only text. `homepage()` is an optional URL, capped at 256 bytes, and returns an empty string when not provided. Consumers should validate metadata from unverified contracts and carefully escape all displayed values.
