Authoryze is for letting an agent make real purchases safely. It issues a single-use card per approved purchase, enforces per-agent and cross-agent limits and merchant rules server-side, routes anything over your threshold to a person, records every purchase per member and agent, and connects to Claude, ChatGPT, Meta's Muse, or a custom agent over MCP, with no crypto and no identity protocol to adopt. Skyfire solves a different problem. It is identity-first: its Know Your Agent (KYA) protocol binds a verified human or business identity to an agent, and its network is built around agent-to-agent payments and monetizing APIs and data, with a newer card checkout path for consumers.
Feature Comparison
| Feature | Authoryze | Skyfire |
|---|---|---|
| Primary focus | Agents making real purchases with human-controlled spending | Agent identity and token-capped payments between agents and APIs |
| Payment model | Single-use card per approved purchase, through the card networks' agentic programs (Visa Intelligent Commerce and Mastercard Agent Pay) | Pre-funded USD wallet, funded by card, USDC on Base, or ACH and wire, with KYA identity tokens and pay tokens that cap what a seller can charge |
| Integration | MCP-native via a single MCP server | REST API, Node and Python SDKs, open KYAPay protocol, hosted MCP server |
| Spend controls | Per-transaction caps, daily/weekly/monthly limits, merchant allow/blocklists, aggregate caps across agents, approval thresholds | Per-agent spending limits (marketing page), per-token maximums |
| Human approval | Built-in approval flow by email and dashboard, with duplicate detection | Not in the API path; card checkout uses an up-front user mandate |
| Teams | Shared team envelope, approvers, per-member and per-agent records, one monthly plan | Not documented |
| Crypto | None, card rails only | USDC on Base as one funding rail |
Different Problems
Authoryze is focused on the case where your agent needs to buy something with a card and you want control and a record of it. The agent asks, the rules engine decides, a person approves anything over the threshold, and the agent gets the single-use card directly from retrieve_card. It is not trying to solve agent identity or agent-to-agent micropayments.
Skyfire's core is identity. A KYA token carries claims for the human principal, the agent, and optionally the platform, so a business can let a verified agent sign up, log in, and pay. Payments work by token: the agent creates a pay token with a USD maximum, the seller charges the actual amount after delivery, and Skyfire settles later. That suits sub-dollar API charges, which card rails handle poorly, and that is the honest tradeoff. We could not find a per-transaction approval feature in its developer docs, so we do not list one.
When Authoryze Is the Right Choice
Choose Authoryze if your need is straightforward. An agent that makes real purchases on a card, with per-agent and cross-agent spending limits, human approval on anything over a threshold, duplicate-purchase protection, shared team envelopes, and a full audit trail, all connected to Claude, ChatGPT, or a custom agent through MCP.
