Self-serve PSD2 bank-data API for EU/UK accounts: accounts, balances and transactions behind a single API key — no eIDAS QWAC/QSealC certificates required. Part of the open-banking.io service (skills repository, MIT).

When to use

  • "What's my balance on ?"
  • "Summarise last month's transactions" / "How much did I spend on groceries?"
  • "Which of my bank connections need re-consent?"
  • Reconciling invoices/payments against bank statement lines

Tool surface

Prefer the official MCP server (read-only tools: list_accounts, get_balances, get_transactions, list_connections): open-banking-io/mcp-server

Direct REST works too: GET /accounts, GET /accounts/{id}/balances, GET /accounts/{id}/transactions.

Quick start

# 1. Sign up at https://open-banking.io (free tier) and get an API key
# 2. Connect a bank (consent flow) — EU/UK, ~600+ institutions
# 3. Read data
curl -H "Authorization: Bearer $OPEN_BANKING_IO_KEY" \
  "https://api.open-banking.io/accounts"

PSD2 quirks worth knowing

  • Consents expire (~90 days by default; some banks cap at 90 days, some 120+) — plan re-consent reminders.
  • Transactions come back as interimBooked (pending) and booked — pending rows flip to booked with the SAME transaction id; treat it as an update, not a new row.
  • Unattended fetch rates are capped per bank (~4 pulls/day typical) — budget polling accordingly.
