Verdicts

Agentcard

Purchases need the user's passkey approval by default, cards carry spending rules, and card creation takes an idempotency key. No status page, published rate limits beyond the token endpoint, or privacy policy of Agentcard's own was found, and the Trust Centre could not be read. Issuing costs $5,000 a month.

Coinbase Developer Platform (Agentic Wallet, AgentKit, CDP MCP)

Operator-set max per call and max per session that the agent can't change, set in the wallet UI. AgentKit on npm is 0.10.4 from December 2025, and its fix for a local file read and public upload path is unreleased.

Before you call either

Agentcard

  1. Mint a platform token with POST /api/v2/oauth/token and cache it for its one hour. The endpoint allows 30 requests per 5 minutes per IP
  2. Send the same Idempotency-Key on every retry of POST /api/v2/cards, and the same idempotency_key on every retry of buy_checkout
  3. Pass source: "issued" to the MCP create_card tool for a card number. Without it the tool may start Vault setup and return a link
  4. Call get_card_details only at the payment form and never log the result. Each read notifies the member and may return approval_required
  5. Treat transaction.authorized and order.* webhooks as the record of a payment, and deduplicate deliveries on the event id

Coinbase Developer Platform (Agentic Wallet, AgentKit, CDP MCP)

  1. Run npx awal@2.12.1 status first and sign in with auth login and auth verify if it fails
  2. Pass --max-amount on every awal x402 pay; 1000000 is $1.00
  3. Send an X-Idempotency-Key on server-wallet writes so a retry can't send twice
  4. Don't register AgentKit's flaunch or zora providers on 0.10.4; they read local files
  5. Give an agent a policy-bound server account or an Agentic Wallet, never a full CDP API key
