Kora

Kora is an agent-to-agent payment infrastructure layer. When one AI agent needs to pay another for a service � data enrichment, web scraping, compute � Kora handles the full flow: receiving the payment request, enforcing spending policy via Ampersend, executing the USDC transfer via Locus on Base, and returning an auditable receipt. Kora now includes a working two-agent demo. Agent B runs an Express server advertising a data enrichment service at $0.10 USDC. Agent A discovers the service, pays via Kora's POST /pay endpoint, then calls Agent B with the payment's requestId. Agent B verifies the payment through Kora's audit API � confirming status, recipient wallet, and amount � before returning enriched data. The full flow executes end-to-end with real USDC on Base mainnet. Under the hood, every payment passes through configurable spending policies (auto-approve small payments, escalate medium ones for human approval, hard-block large ones). Policy enforcement uses the Ampersend SDK's AmpersendTreasurer.onPaymentRequired() for x402 authorization. Payments execute through Locus, routing to wallet addresses or email escrow. Every step is recorded in an append-only audit log with full context. The result is that routine agent-to-agent payments become automatic and trustworthy, without removing human oversight when it matters.
