PayWithMyBank (Trustly)

PayWithMyBank is the U.S. "Pay by Bank" brand of Trustly, a global open-banking payments provider that lets merchants accept payments directly from a consumer's bank account as an alternative to cards. The paywithmybank.com domain now redirects to Trustly, whose AMER developer platform exposes a REST Payments API (OpenAPI 3.1) covering transactions (establish, capture, deposit, cancel, reclaim, refund), payments retrieval, bank-account tokenization and verification, customer records, identity (Trustly ID), account data, dispute recovery, and asynchronous event notifications (webhooks). Authentication is HTTP Basic with a provisioned accessId/accessKey plus a server-generated requestSignature for the client-side Lightbox. Trustly operates the largest open-banking payments network with 12,000+ connected banks across 30+ countries.

Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.

Kin Score

API Evangelist profiles PayWithMyBank (Trustly) the way a machine reads it — 16 machine-readable artifacts across 11 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.

Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — PayWithMyBank (Trustly) scores 50.7/100 (developing), with a separate agent-readiness read of 84/100 (agent native). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

MCP Servers 1

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

Event Specifications 1

Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

AsyncAPI definitions for this provider's event-driven and streaming APIs.

Security Posture 2

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

Agentic Access 1

An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
