Feature request: optional fee-less settlement rail for an ADK agent's authenticated tool/API spend
ADK agents call paid, authenticated APIs through APIHubToolset (src/google/adk/tools/apihub_tool/apihub_toolset.py) and the authenticated function tool wrappers (authenticated_function_tool.py, base_authenticated_tool.py). Every one of those calls settles against an API key or card — there is no fee-less, on-ledger settlement option for an agent's own per-call spend today.
Nano (XNO) is a digital currency that settles peer-to-peer in under one second with a $0.00 transaction fee and no gas. A packaged implementation exists: the feeless402 library (https://pypi.org/project/feeless402/) is a live pay-per-call AI provider and client that settles each MCP/api call on-ledger in XNO, and its nano_pay import is installable from PyPI today.
Would Nano (XNO) as an optional fee-less settlement rail for authenticated tool/API calls from an ADK agent be a useful addition? The shape would be additive: keep the existing API-key / credential path, and add an optional agent-held XNO balance for authenticated tool calls that settles on-ledger with no per-call fee.
