Proxagora

Access a marketplace of APIs designed from the ground up for autonomous AI agents. This platform allows your agents to discover, call, and pay for data in a single, frictionless round trip. Forget complex authentication flows, monthly subscriptions, and managing dozens of API keys.

Key Features

• Instant Access: Agents can call an API, pay via micropayment, and receive data immediately with no signup or traditional authentication required.
• Pay-Per-Call: Use USDC on Base or a pre-funded card balance. Pricing starts from $0.001 per call, so you only pay for what you use.
• Agent-Native Design: Structured JSON inputs and outputs, plus MCP server support, built specifically for autonomous systems.

How Agents Interact

1. Wallet-Native (x402):
   Agents call an endpoint, receive a 402 payment challenge, pay using USDC on Base, and retry with the transaction hash to retrieve data. The wallet acts as identity.

2. API Key (Card-Based):
   Developers can pre-fund an account via card, generate an API key, and let agents make calls without handling payment logic directly.
