K402·EXCHANGE

k402 service exchange · settled on kaspa L1

The marketplace for agent-payable services

Discover a provider, open a payment channel straight to it, and settle per call — LLM inference, chain data, zero-knowledge proofs, covenant tooling. The registry never holds funds. Reputation is settled volume, verified on-chain.

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.
