What could you do if every biller had an API?
One REST endpoint returns normalized bills, balances, and due dates as structured JSON — across 2,400+ billers, no scraping to maintain.
# Retrieve bills for a linked account
curl https://api.billerapi.com/v1/bills \
-H "Authorization: Bearer bak_test_4f2c..."{
"id": "bill_8Kd2Xq",
"biller": "Eversource Energy",
"category": "electric",
"amount_due": 142.19,
"currency": "usd",
"due_date": "2026-07-21",
"status": "unpaid",
"account_last4": "8842"
}The full bill lifecycle in one API
Discover, link, retrieve, and pay — four capabilities on one normalized schema, so you build the integration once and it works for every biller.
Biller discovery
Search 2,400+ supported billers by name, category, or region — utilities, telecom, insurance, lenders, and subscriptions.
Account linking
Drop-in Connect flow handles credentials, MFA, and captchas invisibly. You get a durable link token, never the password.
Bill retrieval
Normalized bills with amounts, due dates, statements, and line items — the same schema whether it came from an API or a scrape.
Bill payment
Initiate payments against a linked account and track them to settlement, with PCI-scoped handling isolated from your systems.
Wire up bills in an afternoon
Four steps from key to first webhook. The Connect flow does the messy part; you handle typed events.
- 1
Create a link token
Call POST /v1/link_tokens server-side with the biller and your customer reference.
/v1/link_tokens - 2
Launch Connect
Hand the token to the drop-in Connect UI. Credentials, MFA, and captchas are handled for you.
- 3
Exchange the token
Swap the public token for a durable account_link_id you store against the customer.
account_link_id - 4
Receive bill.created webhooks
Bills arrive as signed, typed events as soon as they're available — no polling loop to run.
bill.created
{
"type": "bill.created",
"id": "evt_1PQm7z",
"created": 1783041920,
"data": {
"bill_id": "bill_8Kd2Xq",
"account_link_id": "aln_Qb3R",
"amount_due": 142.19,
"due_date": "2026-07-21"
}
}We replaced three scraping vendors with one API. What used to be a fragile pipeline is now four typed webhooks we barely think about.
