Jentic publishes the only available OpenAPI specification for Afterbanks API, keeping it validated and agent-ready. Afterbanks is a Spanish open-banking aggregator that standardises real-time access to bank account data across Spanish, Portuguese, and Latin American banks. The API exposes a small surface — bank form discovery, user account info, and the V3 bank-data service — that lets fintech and lending apps fetch transactions and balances from end-customer bank accounts after consent.

Use Cases

Patterns agents use Afterbanks API API for, with concrete tasks.

★ Lending Underwriting in Iberia and LatAm

Spanish and Latin American lenders use Afterbanks to pull a borrower's last 90-365 days of bank transactions during the loan application flow. The serviceV3 endpoint returns categorised transactions and balances after the borrower completes the bank login, letting underwriting models run cash-flow analysis without paper statements. Typical decisioning latency drops from days to minutes.

Call POST /serviceV3 with a connected user's credentials reference and return the last 90 days of transactions plus the current balance

Personal Finance Aggregation

PFM and budgeting apps use Afterbanks to pull a user's accounts and transactions across multiple Spanish and LatAm banks into a single dashboard. /forms drives the bank picker UI, and /serviceV3 refreshes balances on a scheduled job. Coverage spans the major retail banks in Spain, Portugal, Mexico, and several other Latin American markets.

List forms via GET /forms for country code 'ES', present the bank picker, then refresh transactions via POST /serviceV3 after the user authenticates

Accounting Reconciliation

Accounting and ERP integrations use Afterbanks to import bank transactions for SMB customers and reconcile them against booked invoices. The serviceV3 response is parsed into a ledger feed that the accounting tool matches to existing entries. This avoids the manual CSV upload most Spanish SMBs still rely on.

Pull the last 30 days of transactions via /serviceV3 for an SMB customer's primary account and emit a CSV ready for the accounting tool

AI Agent Cash-Flow Monitoring

Through Jentic, an agent can monitor an SMB's bank cash flow by polling Afterbanks on a schedule and flagging anomalies — large outflows, negative balance risk, repeated failed direct debits. The agent calls /serviceV3 through Jentic without storing the Afterbanks API key, and Jentic enforces credential isolation per call.

Search Jentic for 'fetch afterbanks transactions', load the serviceV3 schema, and execute a daily refresh for a list of SMB customer references

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Afterbanks partner API keys are stored encrypted in the Jentic vault. Agents receive scoped access at execution time and never hold the raw key, which is critical given the regulated banking data exposure.

Intent-based discovery

Agents search Jentic by intent (e.g., 'fetch bank transactions for a customer') and Jentic returns the matching Afterbanks operation with its parameter schema, so the agent calls the right endpoint without reading Afterbanks docs.

Time to first call

Direct Afterbanks integration: 3-5 days including consent flow handling and error recovery. Through Jentic: under 1 hour — search, load schema, execute against a connected user reference.

Related APIs

Alternatives and complements available in the Jentic catalogue.

Alternative

Plaid API

Open banking aggregator with deep US and EU coverage; alternative for projects outside Iberia or LatAm.

Choose Plaid when the customer base is primarily US/UK/EU. Choose Afterbanks when the customer base is Spanish, Portuguese, or Latin American.

Alternative

TrueLayer API

European open banking platform with PSD2 coverage across the UK and EU.

Pick TrueLayer when you need pan-European PSD2 coverage with payment initiation. Afterbanks is a better fit for Iberia and LatAm read-only data.

Alternative

Salt Edge API

Global open banking aggregator with broad emerging-markets coverage.

Use Salt Edge for global multi-region rollouts. Afterbanks is more focused but tends to be cheaper and faster to integrate within its core markets.

Complementary

Accounting platform that consumes bank feeds for reconciliation.

Pair with Afterbanks to push aggregated bank transactions into Xero ledgers for SMB reconciliation workflows.

FAQs

Specific to using Afterbanks API API through Jentic.

Why is there no official OpenAPI spec for Afterbanks API?

Afterbanks does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Afterbanks API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.

What authentication does the Afterbanks API use?

Afterbanks uses an API key issued by Afterbanks for partner integrations. Through Jentic, the key is stored encrypted in the credential vault and only injected at execution time, so the agent never sees the raw secret.

Can I fetch a customer's transactions with the Afterbanks API?

Yes. After the customer authenticates against their bank via the /forms-driven flow, call POST /serviceV3 with the user reference to receive the account list, balances, and transaction history in a single response.

What are the rate limits for the Afterbanks API?

The public spec does not document fixed rate limits. Practically, Afterbanks throttles based on the partner contract — keep refreshes for active users to a few times per day and back off on HTTP 429.

How do I refresh bank data through Jentic?

Search Jentic for 'fetch afterbanks transactions', load the schema for POST /serviceV3, and execute it with the user reference for the connected customer. Jentic returns the parsed transaction list to the agent without exposing the Afterbanks key.

Which countries and banks does Afterbanks cover?

Afterbanks focuses on Spain and Portugal plus several Latin American markets including Mexico. Use GET /forms with a country code to discover the supported banks and the field shape needed for the consent flow.
