API, LLM, and
MCP call.
Zuplo is the unified gateway for APIs and AI — one programmable policy engine for the models your apps call and the agents that call you. Live in minutes, spend under control, every agent call accounted for.

Your API has two new kinds of traffic
Your applications call models, and AI agents call you. Both are API traffic — and both belong behind one gateway.
Outbound
Your product calls LLMs
Every AI feature you ship adds model calls to your traffic — and to your bill. Those calls need routing, spend caps, and guardrails, the same way any critical dependency does.
Inbound
AI agents call your API
MCP made every agent an API consumer. Agents need identity, scoped access, quotas, and docs — real consumers to serve well, not just load to absorb.
Both directions
One gateway in the middle
Auth, rate limits, spend caps, and audit — written once on one programmable policy engine and enforced on every API, LLM, and MCP call, in both directions.
One policy engine. Four products.
Zuplo is the unified gateway for APIs, AI, and MCP. Auth, rate limits, spend caps, and audit run on one programmable policy engine — turn on the surfaces you need without adding a vendor.
Scoped, audited access for AI agents via MCP.

Both directions, in code
The models your apps call and the agents that call you — a base-URL swap on one side, an OpenAPI extension on the other.
Outbound — your app calls LLMs
Keep the OpenAI SDK and point it at your gateway. Provider routing, spend caps, and guardrails apply to every call.
Inbound — agents call your API
Mark OpenAPI operations as MCP tools. Deploy, and agents connect at /mcp — through the same policies as the rest of your API.
Same gateway. Same policies. Both directions.
When you're ready to charge for it, billing is built in.
The same plans, metering, and Stripe billing that run your API cover MCP traffic too — no second billing stack for agent-facing endpoints.
Gate by plan
Check plan entitlement at the gateway before a request — API or MCP — ever reaches your backend.
Meter and bill
Request-level usage flows into Stripe invoices — by request, token, or any unit that costs you money.
Publish a portal
Plans, self-service keys, and documented MCP endpoints — one developer portal for all of it.
Value you can measure in the first month
Lower cost, a smaller attack surface, faster resolution, and new revenue — real results, not a feature checklist.
Cut runaway cost
Dynamic rate limiting absorbs traffic spikes before they hit your origin; token budgets stop AI overspend with a hard cap, not a surprise overage.
Shrink the attack surface
Auth, schema validation, and bot controls reject bad traffic before it reaches your systems — the same policies across every API, model, and MCP server.
Prove what's happening
Every API, LLM, and MCP call is logged and attributed to a consumer, then exported to the SIEM you already run.
Turn traffic into revenue
Meter, price, and bill APIs and AI by request, token, or any unit that costs you — with no billing infrastructure to build.
Resolve issues faster
Request-level tracing pinpoints the slow hop from client to origin, so problems get fixed before they become escalations.
Govern AI for the CISO
Scoped access, audit logs, secret masking, and prompt-injection defense — the answers security teams actually ask for.

Hardware footprint reduction at scale
"The move to Zuplo from our existing API Management vendor was easy, taking just over 2 months to switch mission critical systems, and we're saving over 70% on costs."
Ryan Waites
Senior Director, Blockdaemon
"Zuplo gives us the flexibility to scale efficiently, ensures security and compliance, and reduces operational complexity so we can focus on building new capabilities."

To launch MCP server on regulated APIs
"We didn't touch a line of code, it's just plug and play. The results were very surprising, in just a couple of hours we had a fully working MCP Server."
