See the pay-per-call loop work with no setup: we grant a small tKAS credit and meter a real call to the kaspa-expert model — RAG-grounded on current Kaspa knowledge, so ask it anything about Kaspa. This is a testnet demo; no real value moves. For real usage on mainnet, open a funded session and pay in KAS.
