Agents can search APIs, see what they do, and understand the cost before using them.
Payment infrastructure for autonomous software
Apiosk lets providers publish APIs with built-in pricing and gives AI agents a single path to find, pay for, and use them.
One simple way for AI agents to use and pay for APIs.
Instead of managing API keys, subscriptions, and billing per provider, Apiosk gives you one place where agents can find APIs, use them, and pay per request automatically.
Every API runs through the same gateway. No custom integrations, no different setups per provider.
Each request includes the payment. No subscriptions, no invoices, no separate billing systems.
APIs are instantly usable as tools for agents. No need to build or maintain wrappers.
Use it via a simple SDK or plug it directly into your agent environment.
Set budgets, control usage, and track spending from one place.
Watch an agent call a paid API.
A single POST carries the x402 payment header. The gateway verifies, routes, and settles — all in one round-trip.
Official MCP server
A remote MCP endpoint that exposes Apiosk discovery and execution as agent-native tools. It generates dynamic tool entries from listing metadata, so new APIs become available without hand-maintained wrappers.

JavaScript SDK
Discovery, metadata, passthrough, and uniform /execute helpers with typed 402 errors and optional x402 auto-pay for Base wallets.
