Loomal Index vs AWS Marketplace protocol-native vs cloud-account-native.
AWS Marketplace sells software that deploys into AWS accounts and bills through AWS. Loomal Index sells calls to MCP servers and APIs over an open protocol, with no cloud relationship required on either side. Different buyers, different units, different rails.
AWS Marketplace is Amazon's marketplace for third-party software, SaaS, APIs, and data products that deploy into AWS accounts and bill through AWS. Loomal Index is an index of MCP servers and APIs where every listing is payable per call over x402.
These rarely compete head-to-head today — but if you sell an API or data product and you're deciding where AI agents will buy it from, the architectural difference between them is exactly the thing to understand.
What AWS Marketplace does well
For organizations already running on AWS, the Marketplace collapses procurement: a third-party product becomes a line item on the AWS bill, deployable into the AWS account the team already operates. Software, SaaS, API, and data listings all flow through one billing relationship a company has already negotiated.
That's genuinely valuable for enterprise sales. If your buyer is a company with an AWS commit and a procurement process, meeting them inside that process is a real advantage.
The AWS account is the gate
Everything in AWS Marketplace presumes an AWS relationship: purchases tie to an AWS billing account and products deploy into AWS infrastructure. The buyer is an organization, the unit is a subscription or contract, and the human doing the buying works inside a cloud account.
An autonomous agent has none of that. It doesn't hold an AWS billing account, can't sign a procurement agreement, and doesn't want a deployment — it wants one tool call, right now, priced in something it can pay.
What Loomal Index adds
Loomal listings are protocol-based — MCP for the interface, x402 for the payment — and cloud-agnostic. Your server can run on AWS, another cloud, or a box under your desk; an agent on any infrastructure can discover it through the index and pay it without any AWS relationship.
The unit of commerce is a single call: the agent hits your endpoint, receives an HTTP 402 with the price (minimum $0.01), pays in USDC, and the payment settles on Base in roughly two seconds — before your handler runs. Every call yields an Ed25519 signed receipt, and there are no chargebacks. No contract, no provisioning, no account on either side of the transaction.
Different units of commerce
The comparison reduces to granularity. AWS Marketplace sells deployments and subscriptions to organizations through a cloud billing account. Loomal Index sells individual calls to whoever — or whatever — shows up with a wallet. One is procurement infrastructure for companies; the other is transaction infrastructure for agents.
That's also why neither replaces the other. A subscription negotiated through cloud procurement and a $0.01 metered call answer different questions.
When to use which
Sell through AWS Marketplace when your buyers are AWS-based organizations and your product fits subscription or contract pricing inside their cloud bill. List on Loomal Index when you want per-call revenue from AI agents regardless of whose cloud anyone uses. If you sell an API or data product, doing both covers two distinct buyer populations: procurement teams on one side, autonomous agents on the other. Loomal's fee is 5% on settled transactions, currently waived.
FAQ
Is Loomal Index an AWS Marketplace alternative?
Only for one slice of the job. AWS Marketplace handles enterprise procurement — subscriptions and deployments billed through an AWS account. Loomal handles per-call sales to AI agents over x402, with no cloud account involved. An API vendor might reasonably use both for different buyers.
Does AWS Marketplace support x402 or agent payments?
AWS Marketplace billing runs through the buyer's AWS account. For anything about agent-initiated or stablecoin payments, check AWS's current documentation, as this space is evolving quickly as of mid-2026. On Loomal, x402 is how every listing gets paid.
Does my server need to run on a specific cloud to list on Loomal?
No. Loomal listings are protocol-based — MCP plus x402 — so the index doesn't care where your server runs. AWS, another provider, or your own hardware all work; agents pay the endpoint, not the infrastructure behind it.
How small can a transaction on Loomal be?
The minimum per-call price is $0.01, paid in USDC and settled on Base in about two seconds. That granularity is the point — it's a unit no procurement-based marketplace is built to meter.
