Aeropay
Aeropay is a Chicago-based fintech operating a pay-by-bank network that moves money directly between consumer bank accounts and merchants over ACH, Request for Payment (RfP) and RTP rails, without cards. The product suite is Aerosync (branded bank linking and account connectivity), Pay (merchant acceptance of bank payments), Payout (real-time merchant-to-consumer credits) and Guard (risk decisioning and fraud prevention). Integrators use the Aeropay v2 REST API — a 32-operation OpenAPI 3.0.0 contract covering token issuance, user creation and MFA confirmation, bank linking through an aggregator widget, standard, preauthorized, payout and reversal transactions, transaction search, payment links, webhook subscriptions, reporting and merchant reputation — alongside first-party Aerosync bank-linking SDKs for web, React Native, Android, iOS and Flutter. Aeropay publishes a documentation llms.txt, a remote MCP server for the API reference, a nine-topic webhook catalog, a 91-entry error glossary, a NACHA ACH return-code glossary and a substantial sandbox exception-scenario harness. It is SOC 2 compliant and audits its ACH operations annually against NACHA standards.
Aeropay publishes 9 API contracts indexed on the APIs.io network, including Authentication API, Bank Connection API, Create & Manage Transactions API, and 6 more. Tagged areas include Payments, Pay by Bank, ACH, Open Banking, and Fintech.
The Aeropay catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.
Aeropay’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, pricing, and 37 more developer resources.

Kin Score
Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.
| Market | Position | Depth | Registered MCP server | Declares compatibility |
|---|---|---|---|---|
| Canada RPAA Payment Service Providers (Bank of Canada registry + Payments Canada) | regulated | 39.6 (thin) | - | - |
Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
Standards implemented 3
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
