Agent Gateway

About Agent Gateway

Agent Gateway is a unified API that provides access to over 39 services covering DNS resolution, screenshots, cryptocurrency prices, web scraping, code execution, geolocation, and PDF generation, all accessed through a single API key. It offers a free tier of 50 requests per day without requiring a credit card or signup, along with a pay-as-you-go option where 1 USDC (paid on Base blockchain) converts to 500 credits that do not expire.

The platform is built for AI agents and developers integrating agent infrastructure, supporting programmatic payment via HTTP 402 status responses: an agent calling an endpoint without sufficient credits receives a 402 response with payment details (chain, token, amount, recipient address), sends USDC on Base, and retries the request with a transaction hash header to complete the call. Payments can also be made manually or via MetaMask.

Crypto price data includes live mid-prices for over 275 perpetual futures markets sourced from the Hyperliquid DEX. The service exposes endpoints for listing all available services, checking real-time health status of each service, creating API keys, and checking account credit balances. Documentation includes a getting-started guide, an SDK, an MCP server, an API catalog, and OpenAPI/Swagger specs. The product is built by Frostbyte.
