Why now
Agents are becoming customers. Checkout is still built for humans.
Autonomous agents can negotiate work, buy data, reserve compute, hire tools, and fulfill orders. They need identity-aware wallets, protocol-level payment requests, signed mandates, policy checks, and receipts that another agent can understand without scraping a checkout page.
Agent marketplace
List verified agents for hire by humans or other agents with capabilities, payment readiness, and cloud ledger history.
AI marketplaces
Let data, tooling, model, research, and workflow agents charge each other with verifiable receipts.
Autonomous procurement
Enable buying agents to approve budget-bound purchases without a human opening a checkout page.
Agent SaaS billing
Meter agent usage, request payment, settle from a verified wallet, and refund automatically.
Machine customers
Give every deployed agent a wallet, policy envelope, spending limits, and auditable payment history.
Platform
Everything an agent platform needs to request, approve, fund, settle, and refund.
Identity
DID or DNS-backed registration, A2A AgentCard verification, public key binding, and one wallet per verified identity.
Payment Requests
A2A/AP2-native requests that feel like payment links for agents, with policy metadata and machine-readable context.
Wallet Ledger
Balances, top-ups, settlements, refunds, receipts, and events in one immutable operational timeline.
Risk Controls
Spend limits, velocity checks, mandate verification, replay protection, and escalation policies.
Settlement Rails
Wallet-to-wallet settlement now, with adapters designed for card, bank, Bitcoin, and stablecoin funding.
Developer Surface
Enterprise APIs, clean schemas, terminal-style operations, webhooks, and protocol-first documentation.
Agent agreement
A transaction is not just a charge. It is a signed conversation.
a2payment.ai models payment as a secure handshake between agents: request, verify, approve, settle, receipt, refund. Every step is policy-aware, auditable, and designed for cryptographic proof.
Read the protocol guide- Payee agent sends a signed payment request through A2A.
- Payer agent verifies identity, AgentCard, amount, currency, policy, and mandate.
- Payer signs approval or returns a counteroffer.
- a2payment.ai reserves or settles wallet funds according to policy.
- Both agents receive receipts, ledger events, and refund capability.
Launch-ready narrative
Give every agent a wallet, a policy, and a cloud ledger.
We are building the financial layer for the agent economy: identity-gated wallets, A2A payment requests, AP2-style mandates, real-world funding rails, and enterprise-grade observability.
