Benchmark Rate

Overview

Benchmark Rate provides the current values for the key risk-free reference rates used in global financial markets. These rates replaced LIBOR and are used for derivatives, loans, mortgages, and other financial contracts. Data is refreshed daily from FRED.

Endpoint

One host, one path per API. The block below shows this call in four languages; every one of them is the same HTTP request. Making requests covers the timeouts, retries and parameter rules that apply to all of them. The SDKs wrap the same call in a typed client.

if (!res.ok) throw new Error(`${res.status} ${await res.text()}`);

const { data } = await res.json();

package main

import (
	"fmt"
	"io"
	"net/http"
)

func main() {
	req, _ := http.NewRequest("GET", "https://api.apiverve.com/v1/benchmarkrate?rate=SOFR", nil)
	req.Header.Set("x-api-key", "your_api_key_here")

	res, err := http.DefaultClient.Do(req)
	if err != nil {
		panic(err)
	}
	defer res.Body.Close()

	out, _ := io.ReadAll(res.Body)
	fmt.Println(string(out))
}

Replace your_api_key_here with the key from your dashboard. When the inputs arrive as a list rather than one at a time, batch requests run up to 200 of them through this same API in a single call.

Authentication

Send your key in the x-api-key header. That is the only auth step — there is no token exchange and no per-endpoint scope to configure. Authentication covers creating, rotating and revoking keys.

Parameters

Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them.

Response

Every API returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape. Response format covers the envelope, the other output formats and how premium fields are withheld.

{
  "status": "ok",
  "error": null,
  "data": {
    "rate": "SOFR",
    "name": "Secured Overnight Financing Rate",
    "currency": "USD",

    "changeDirection": "down",
    "previousValue": 4.33,

  }
}

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change. Error handling covers the full status list and which of them are worth retrying.

Use cases

Floating Loan Servicing

Lending software recalculates monthly interest charges on adjustable corporate credit facilities by fetching the latest published SOFR or SONIA figures.

Interest Rate Swaps

To price floating-leg derivative contracts, quantitative analysts pull current SARON and ESTR levels to mark overnight indexed swaps to market.

Treasury Risk Monitoring

Treasury teams monitor rate shifts across dollar, pound, and euro credit lines by reading each day's movement direction.

Settlement Contract Auditing

Before settling cross-currency accounts, compliance engines verify applied borrowing rates against official published values for the matching transaction date.

Other ways to use Benchmark Rate

Set up Benchmark Rate on APIVerve, or reach the same source a different way. Your APIVerve account and credits work on all of them — one key, one balance.
