NOK Exchange Rates API (Norges Bank)

Q: Can my agent use this over MCP?

Yes. Connect to https://veldora.no/mcp and call get_exchange_rates. Listing the tools is free; each call costs $0.005.

What you get

base (always NOK), date and rates: for each currency the code, unit_multiplier and nok_per_unit.
nok_per_unit is the rate as Norges Bank quotes it: NOK per unit_multiplier units of the currency (100 for JPY, SEK and DKK, otherwise 1). Divide by unit_multiplier for NOK per single unit.
With from and to a daily series of observations (date and nok_per_unit) per currency, at most 366 days.
meta.requested_date is what you asked for and meta.date is the business day the rates are from. meta.not_found lists requested currencies without a rate.
Filters: currencies (ISO 4217 codes, at most 40), date, or from and to. The trade-weighted indices TWI and I44 are left out.

Example

Rates for USD and JPY on a given date:

curl "https://veldora.no/v1/exchange-rates?currencies=USD,JPY&date=2026-10-03"

{
  "data": {
    "date": "2026-10-02",
    "base": "NOK",
    "rates": [
      { "currency": "JPY", "unit_multiplier": 100, "nok_per_unit": 6.1198 },
      { "currency": "USD", "unit_multiplier": 1, "nok_per_unit": 9.6494 }
    ]
  },
  "meta": { "source": "norges-bank", "fetched_at": "2026-10-13T08:15:00Z", "stale": false, "requested_date": "2026-10-03", "date": "2026-10-02", "not_found": [], "attribution": "Source: Norges Bank." }
}

Without payment this returns 402 with the price. With an x402 client such as @x402/fetch the same request returns the JSON above, trimmed here. The values are an illustration of the shape; 3 October 2026 is a Saturday, so the rates are from Friday 2 October.

Price and MCP tools

Endpoint	What it does	MCP tool	Price
`GET /v1/exchange-rates`	Exchange rates against NOK	`get_exchange_rates`	$0.005

Per successful call, in USD, paid as USDC on Base. The MCP server is at https://veldora.no/mcp.

How payment works

Your agent sends a normal HTTP request and gets 402 Payment Required with the price. It signs a USDC authorization on Base for that amount and repeats the request, and Veldora returns the data with a receipt. There is no account or API key, and failed calls are not charged. See Pay per call and the payment section of the docs.

Questions

What is the licence of the exchange rate data?

Norges Bank allows copying with the bank named as the source. Every response carries Source: Norges Bank. in meta.attribution. See Norges Bank's copyright notice.

How fresh is the data?

Rates are read live from Norges Bank and cached for up to 10 minutes. Norges Bank publishes on business days only, so a weekend or holiday gives the prior business day.

What happens if a call fails?

You are not charged for any response with status 400 or higher. If no rate is found at all you get 404 for free, and if Norges Bank does not answer you get 503 and no charge.

Do I need an API key or an account?

No. Your agent pays per call in USDC on Base with the x402 protocol.

Can my agent use this over MCP?
