Payment-native API access for autonomous agents. No subscriptions, no credentials.
Apiosk replaces subscriptions and key sprawl with a direct payment-to-access flow. Agents buy the call they need, when they need it, and providers get a clear monetized route.
The gateway is not the whole story anymore. Apiosk now has an official MCP surface for agent clients, an installable gateway skill for coding agents, and a JavaScript SDK for application code, so discovery and paid execution live in the same workflow.
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.
Remote MCP endpoint is live now at apiosk-mcp.fly.dev/mcp
Catalog-backed discovery with search, listing detail, and generic execute tools

Install the Apiosk gateway skill in supported coding-agent runtimes to browse listings and call paid APIs with saved connect-token access.
No API keys. No subscriptions. Just request → payment → access.
Agents don't need seats. They need a route, a price, and a guarantee. That's what these deliver.
Initiate, verify and track a payment via x402 — without API key rotation or credential handoff between agent steps.
Retrieve structured KYB data for agent-driven onboarding flows. Let agents verify merchants without human handoff in the loop.
Real-time risk scoring on transaction intent before settlement. Built for agents that commit capital and need a signal before they do.
Pay with USDC on Base via x402. Built for AI agents and developers with instant settlement.
The primary rail. Built for AI agents and developers. No account, no KYC, no subscriptions — just a wallet and a balance.
Spin up a route, inspect live APIs, and see the full x402 payment handshake before you wire it into production.
