API-first by default. MCP-native across every product. Real documentation, not marketing pages dressed as docs. If you're integrating Paying.co into your stack, here's what to expect — clean endpoints, predictable auth, well-typed responses, and webhooks that fire when they say they will.
We've integrated against enough payment APIs to know what makes a developer experience good or terrible. Here are the principles we hold ourselves to.
Every endpoint documented with request shapes, response shapes, edge cases, and runnable examples. No “contact your account manager for details.” If a developer can't self-serve their integration end-to-end from the docs alone, the docs are broken.
Every product in our suite ships with an MCP server — Landed.net, Puny.io, and Ask all expose their capabilities to AI agents and tools natively. Building agentic payment workflows shouldn't require glue code to convert your APIs into something an LLM can use.
Bearer tokens. Scoped API keys. Webhook signatures you can actually verify. Error responses with stable codes, machine-readable details, and human-readable messages. The boring fundamentals other payment APIs get wrong — we get right.
The full developer surface across Paying.co products and services. Built to be self-serve, opinionated where it counts, and flexible where it should be.
Build, deploy, and manage landing pages programmatically. Full REST API for site creation, content management, and publishing. Used in production by teams shipping at scale.
View reference MCP ServerSpin up landing pages, manage templates, and publish content directly from AI agents. MCP-native integration for Claude, ChatGPT, and any MCP-compatible client.
Connect MCP MCP ServerShorten links, create capsules, and manage secure URLs programmatically. Branded short URLs, expiration controls, and click analytics — all exposed via MCP.
Connect MCP MCP ServerSend branded payment requests via QR, SMS, and email from agentic workflows. Multi-gateway support, white-label routing, and webhook callbacks for payment confirmation.
Connect MCP OperationsReal-time status across every Paying.co service and product. Subscribe via RSS or webhook for incident notifications. Component-level health visibility, not just a green dot.

Learn moreEach product in our suite ships with both REST APIs and MCP server interfaces. Build classic integrations or wire them into agentic workflows — same primitives, different protocols.
REST API + MCP server. Create sites, manage templates, publish content programmatically.
REST API + MCP server. Shorten links, manage capsules, track usage with full API access.
REST API + MCP server. Send payment requests, manage merchants, handle callbacks via webhooks.
Unified gateway API across every major processor. One client library, every rail.
