Publish a production-grade API in 10 minutes. Let us do the rest.
ApyHub turns your API into a marketplace-ready service — docs, validation, schemas, certification, billing, support, agent-readiness — with AI doing the heavy lifting. Bring an endpoint. We'll handle everything between you and your first paying developer.
From your endpoint to the catalog. With an AI doing the boring parts.
Most API marketplaces hand you a 40-field submission form, a documentation template, a validation checklist, and a 2-week review cycle. We hand you a single setup flow.
Point us at your endpoint. Our AI generates the OpenAPI spec, drafts the documentation, builds the request/response examples, validates the schema against the ApyHub standard, and previews how your API will look in the catalog — for humans and for agents. You review, you edit, you publish.
Ten minutes from "I have an API" to "developers can call it."
You ship the endpoint. We ship everything around it.
A paying audience, already inside
65,000+ developers and teams already subscribed to the catalog — your API is available to all of them the moment it goes live. No marketing site, no SEO grind, no cold outreach. They're already paying for the shelf you're listed on.
The supply-chain badge enterprises ask for
Every published API ships with machine-readable certification — data residency, retention, sub-processors, standards alignment (GDPR, SOC 2, ISO 27001). The same artifact that gets you auto-shortlisted in enterprise procurement reviews. You inherit a credibility surface that takes solo providers years to build.
Agent-readiness, built in
Every endpoint you publish is MCP-ready by default. Claude, Cursor, and any agent runtime can discover and call your API without you writing a wrapper, a tool definition, or a single line of glue code. The category of buyer that didn't exist three years ago now finds you on day one.
You're in control of what matters
Set your own price in atoms. Change it whenever you want. Push new versions on your schedule. Decide what's premium and what's free-tier. See real-time usage, revenue, and consumption patterns. The platform works for you, not the other way around.
Four steps. Most providers finish in under ten minutes.
Set your price. Change your mind. Get paid.
Atoms are ApyHub's pricing unit — small enough to bill a tiny endpoint, expressive enough to price a 200ms LLM call. You choose how many atoms a call to your API costs. Price flat, tier by complexity, or vary by payload size.
Your customers see one bill, one currency, one subscription. You see clean per-call revenue, real-time consumption, and a transparent split — no hidden fees, no surprise deductions, no negotiating per-API contracts with every enterprise that comes through procurement.
Payouts run monthly. Companies invoice us. Individual developers don't — we transfer earnings directly to your bank.
You own it. You price it. You decide where it goes next.
You retain 100% of the intellectual property in your API. Our provider agreement protects your IP and explicitly allows you to monetize the same API elsewhere — your own product, another marketplace, an enterprise contract you signed last quarter. Exclusivity is nice. We don't ask for it.
You set your own price in atoms and change it whenever you want. Tier it, flatten it, raise it, drop it — the controls are yours and the changes apply on your schedule.
Host the API anywhere you can route HTTPS from. Your cloud, your VPS, your on-prem rack, our infrastructure — we don't care where the bytes live, as long as we can reach them and your consumers can rely on them.
Want to retire an API? We'll work with you on a sunset path that respects the paying customers depending on it — proper notice, clear migration windows, no surprises for the developers who built on top of you. The platform's job is to make that handover clean.
The questions we hear most often.
How long does publishing actually take?
10 minutes for simple endpoints (single REST endpoint, standard auth). Longer for complex APIs with many endpoints, custom authentication, or webhooks — but the AI handles the heavy lifting in all cases. Most providers finish their first publish in under an hour.
Do agents count as users? Do I get paid for agent calls?
Yes. Every call is a call, regardless of caller. Whether a developer triggers it from their IDE or an agent calls it through MCP, you earn the same.
What if I want to retire an API later?
We'll work with you on a sunset path that respects the customers depending on it. Proper notice, clear migration windows, predictable timeline. The handover is part of the service.
Who can become an API provider?
Anyone with a hosted HTTPS API and the ability to sign a standard provider agreement. Solo developers, startups, and established companies are all welcome — there's no minimum company size, audience, or revenue threshold.
How do I get started?
Click "List your API now" above, create an account (or sign in), and start the publishing flow. Drop in your URL or OpenAPI spec and the AI takes it from there.
What types of APIs can I list?
Anything HTTPS-callable: REST utilities, AI/LLM endpoints, file conversion, data feeds, search, geocoding, payments — we don't gate by category. If your API is useful and well-documented, it belongs in the catalog.
How are payouts handled?
Monthly. Companies invoice us against the revenue statement we send. Individual developers receive direct bank transfers — no invoice required on your end. There's no minimum payout threshold.
How is tax handled?
We collect and report VAT for EU sales — you receive net-of-VAT revenue and a payment statement you can file. For payouts to companies we issue a statement against your invoice; for individual developers we issue tax forms appropriate to your jurisdiction.
Can individual developers publish, or do I need a company?
Individual developers can publish — no company registration required. We pay you directly and handle the tax reporting on our side.
Who owns the IP in my API?
You do. 100%. The provider agreement protects your rights and explicitly allows you to sell the same API elsewhere — your own product, another marketplace, direct enterprise contracts. We never claim exclusivity.
Where can I host the API? Do you take a container?
Host wherever HTTPS reaches: your own cloud, a VPS, on-prem, or our infrastructure. We don't require a container. We support multiple versions per API so you can publish v2 without breaking v1 consumers.
Ten minutes between you and the catalog.
Free to list. No setup fees. No exclusivity required. Your IP, your pricing, your call.
