Every feature request ever submitted, public and unauthenticated. Free.

submit_feedback

Submit a feature request ($1 anti-spam fee, charged to the prepaid balance when funded). Auth required. Payment flow: call once without x_payment — a 402 reply lists the exact EIP-3009 requirements (a…

confirm_delegation

Activate a prepared delegation by supplying the owner's signature over its enable digest. Auth required.

renew_delegation

Renew an active delegation: same scope, fresh expiry, no authority gap. Returns a NEW digest to sign and confirm exactly like prepare_delegation. Auth required.

get_balance

Prepaid fee balance: settled credits minus fee debits. Auth required.
