payment_summary - Nevermined Documentation

Count your Router payment requests over a period. This reports numbers of payments, not money. Reading charges nothing. Needs a credential. Auth: key / grant · Charges: nothing

Arguments

Argument	Required	Type	Description
`from`	no	string	ISO-8601 lower bound on `createdAt`, inclusive.
`to`	no	string	ISO-8601 upper bound on `createdAt`, inclusive.

Returns

A total, a daily series (oldest first), and a charged-not-delivered count:

{
  "total": 42,
  "series": [
    { "date": "2026-10-01", "value": 18 },
    { "date": "2026-10-02", "value": 24 }
  ],
  "chargedNotDelivered": 0
}

total is uncapped (unlike list_payments’s 1000-record cap).
chargedNotDelivered is the count of failed payments in the period whose merchant charge was observed — flag a non-zero count to the user.

For amounts use list_payments; for what’s spent or left use get_budget.

Try it

Ask your assistant:

How many payments have I made this week?
