What is an AISP?

An AISP (Account Information Service Provider) is a regulated third-party company authorized to access a customer's bank account data, with their consent, in read-only mode. AISPs can view transaction histories, balances, and account details across multiple banks, but they cannot move money or initiate payments.

AISPs were formalized under PSD2 (the EU's Second Payment Services Directive), which required banks to open access to customer account data through secure APIs. The UK adopted these rules through the Payment Services Regulations 2017, and similar frameworks are emerging in Australia (Consumer Data Right), Brazil, and other markets.

How AISPs work

The key constraint: AISPs have read-only access. They can look at data but cannot initiate transactions. For payment initiation, you need a PISP (Payment Initiation Service Provider). Some companies hold both licenses.

AISP vs. PISP

Many open banking providers hold both AISP and PISP licenses, offering data aggregation and payment initiation through a single API.

Why AISPs matter for billing and monetization

For companies in the payments and financial infrastructure space, AISPs are part of the broader open banking ecosystem that's reshaping how businesses access financial data, verify customers, and streamline onboarding.

Solvimon customers like Yapily, TrueLayer, and Montonio operate within this ecosystem, connecting businesses to financial institutions across Europe. Their billing complexity, with per-API-call metering, volume-based tiers, and bespoke enterprise contracts, is a direct result of how open banking products are consumed and monetized.
