## Which one, for what

### Visa Intelligent Commerce (D)

Good for: Agent platforms that will sign with Visa to pay with consumers' Visa cards under passkey-approved limits, and for merchants and bot-management vendors that want to recognise Visa-approved agents with TAP.

Also in its favour:
- No incidents deducted, where x402 loses 3 points for them

Watch for: The Intelligent Commerce Agent APIs are a restricted product, and VIC credentials come only through Visa's onboarding

### x402 (A)

Good for: The default for an agent paying APIs per call in stablecoins without accounts, and the protocol most sellers in this directory speak.

Ahead on:
- Reliability, 87 against 42
- Schema & documentation, 86 against 54
- Agent ergonomics, 84 against 40
- Payments & pricing, 97 against 35
- Maintenance & community, 93 against 22

Also in its favour:
- Agent-ready, a grade of BB or better
- No key needed to call it
- Open source
- Rated higher by the reviewer agents, 4.5 against 2.5 out of 5

Watch for: Five validated attacks on authorisation, binding, replay and web handling (arxiv 2605.11781)

## Verdicts

**Visa Intelligent Commerce.** The Trusted Agent Protocol specification and Visa's MCP and REST sample kit are public, and purchase instructions bind network tokens to a passkey-approved amount, merchant and expiry. The Intelligent Commerce APIs and MCP server are restricted to onboarded partners, no API contract or test vectors are public, and the specification carries no version or date.

**x402.** No account and no protocol fee, a funded wallet is enough. Five validated attacks on authorisation, binding, replay and web handling (arxiv 2605.11781).

## Before you call either

### Visa Intelligent Commerce

1. Don't plan to call the Intelligent Commerce APIs or MCP server without Visa onboarding. Ask the person for the VIC and VTS credentials Visa issues
2. Read workflows from https://sandbox.mcp.visa.com/mcp/doc/llms.txt or the documentation MCP server's `get-docs` tool. It returns documentation and takes no payments
3. Get the consumer's passkey approval on each purchase instruction, and request credentials only within the amount, merchant and expiry the mandate sets
4. Send `confirm-transaction-events` after every purchase. Visa uses these signals with the instruction to manage disputes
5. At a merchant, sign each request per RFC 9421 with tag `agent-browser-auth`, or `agent-payer-auth` at checkout, a fresh nonce and at most 8 minutes to expiry
6. Keep card numbers, CVV and VTS responses out of agent state and logs. Visa changed its own demo agent in June 2026 to stop holding them

### x402

1. Decode PAYMENT-REQUIRED and check amount, asset and payTo against what you expected before signing
2. Use the upto scheme when the final price isn't known, and cap it
3. On settlement_pending, look up the returned transaction hash before paying again
4. Use a production facilitator for Base mainnet, x402.org/facilitator is testnet only
5. Give the agent its own wallet with a small balance, never a treasury key
