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
Remote MCP + npm package
A live MCP surface for ChatGPT, GPT-native clients, Claude Code, Codex, and other agent runtimes. It generates dynamic tool entries from listing metadata, so new APIs become available without hand-maintained wrappers.
Hosted OAuth flow for GPT-native clients that cannot send raw authenticated gateway POSTs
Catalog-backed discovery with search, listing detail, and generic execute tools
Dynamic API-specific tools generated from Apiosk listing metadata

GPT-Native MCP
Set up Apiosk in ChatGPT.
Connect the hosted MCP endpoint, complete hosted OAuth, and use discovery plus paid tools directly in chat.
Step 01
Add the remote MCP endpoint
Use https://mcp.apiosk.com/mcp in ChatGPT or another GPT-native MCP client.
Step 02
Finish OAuth once
Sign in with your Apiosk dashboard account to unlock protected tools and paid execution.
Step 03
Run tools inside the same chat
Search the catalog, inspect listings, and execute paid actions without switching back to raw HTTP.
For manual HTTP execution or wallet-bound x402 outside MCP, use the direct gateway with `X-Apiosk-Connect-Token`.
