Authoryze and Crossmint both let AI agents make purchases without exposing your real card, with different approaches. Authoryze issues a dedicated single-use virtual card for each approved purchase and is built MCP-native, so it plugs directly into agents like Claude and ChatGPT. Crossmint takes a broader infrastructure approach. Its Agent Cards issue a one-time card number or network token from the user's existing Visa or Mastercard over Visa Intelligent Commerce or Mastercard Agent Pay, alongside stablecoin wallets across many chains.
Feature Comparison
| Feature | Authoryze | Crossmint |
|---|---|---|
| Card model | Dedicated single-use virtual card issued per purchase | One-time number or network token derived from an existing Visa or Mastercard, expires in minutes |
| Integration | MCP-native (Claude, ChatGPT, custom agents) via a single MCP server | API/SDK, plus lobster.cash, Crossmint's own skill and CLI for Claude Code, OpenClaw, Cursor, Codex, and Gemini |
| Spend controls | Per-transaction caps, daily/weekly/monthly limits, merchant allow/blocklists, approval over thresholds | Amount, merchant, and expiry on each order intent; threshold approvals and audit logs appear in marketing copy, not the card API docs |
| Human approval | Built-in email approval flow with duplicate detection | One-time passkey authorization of an intent, no threshold-triggered review documented |
| Stablecoin / crypto | None, card rails only | Yes (USDC, x402, many chains) |
| Card data exposure | Agent never sees your real card; single-use details via one-time link | One-time number on network rails; the encrypted fallback hands the agent the user's real card |
Integration Model
Authoryze is MCP-native, so connecting it to Claude, ChatGPT, or a custom agent framework is adding one MCP server to your config. No SDK wiring, no new client library. The agent calls request_purchase, rules are enforced server-side, and the card is issued. Crossmint is API/SDK-first and requires integrating against their REST or SDK surface. It also ships lobster.cash, an agent-facing skill and CLI that installs into Claude Code, OpenClaw, Cursor, Codex, Gemini, and Hermes, which gives it reach into coding agents without an MCP server. If your agents already speak MCP, Authoryze is the lighter lift.
Single-Use Cards on Both Sides
Both products give the agent a credential that dies after one purchase. Authoryze issues a fresh virtual card scoped to the approved amount. Crossmint's Agent Cards return a one-time number or network token bound to the amount and merchant, issued over Visa Intelligent Commerce or Mastercard Agent Pay, with expiries measured in minutes. The difference is what happens when network rails are unavailable. Crossmint's docs describe a fallback that returns the user's real saved card, encrypted to the agent, and are clear that the decrypted value is the real card and not a one-time number. Authoryze has no such fallback. If a card cannot be issued, the request fails.
Spend controls differ too. Crossmint's card permissions API sets an amount, a description, an expiry, and an optional merchant on each order intent, and the user authorizes the intent once with a passkey. Its marketing pages describe spending limits, merchant whitelisting, threshold-based human approval, and auditable logs, but we could not find those as documented API features. Authoryze enforces per-agent and cross-agent limits, merchant allowlists, and an approval threshold on every request server-side.
Simple and Card-Only
Authoryze is deliberately card-only and crypto-free. Single-use virtual cards on existing card rails, no stablecoins, wallets, or chains to manage. For teams who want agent spending to stay simple, predictable, and on cards, that focus is the point. Crossmint additionally spans stablecoin rails, including USDC and x402 across multiple chains, and acts as Merchant of Record for its Agent Checkouts product, for teams whose use cases require that.
When Authoryze Is the Right Choice
Choose Authoryze if you want the simplest MCP-native way to give agents card spending with strong human-in-the-loop controls, duplicate purchase protection, and a full audit trail, without taking on crypto rails or additional infrastructure. Per-agent rules, cross-agent aggregate caps, and email approval for over-threshold requests are built in from day one.
