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.

The tool
Once your client is connected to the VerveKit server, this appears in its tool list as BenchmarkRateSkill. It is read-only and open-world — it fetches and never mutates anything on your side — so most clients call it without asking you to confirm.
{
"name": "BenchmarkRateSkill",
"arguments": {
"rate": "SOFR"
}
}You do not name the tool yourself; the model picks it. Asking about SOFR in the terms this skill covers is enough for it to reach for BenchmarkRateSkill on its own — naming it explicitly also works, and is the way to force the call.
Connecting
One server URL covers every skill in the catalog, including this one. Authorization is OAuth: the client opens a browser once, and there is no key to paste into a config file.

"vervekit": {

Arguments
These are the properties on the tool's inputSchema, so a well-behaved client validates them before the call is made. Premium arguments are accepted on every plan but only take effect on plans that include them.
| Argument | Type | Description |
|---|---|---|
rateRequired | string | The benchmark rate to retrieveSOFRSONIAESTRTONASARON |
What the model gets back
The result carries a structuredContent object matching the tool's declared outputSchema, so a client reads fields without parsing prose. status is "ok" and error is null on success; a null field means the value was not available for that input, not that the call failed.

"status": "ok",
"error": null,

"rate": "SOFR",
"name": "Secured Overnight Financing Rate",

}
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.
| Field | Type | Example | Description |
|---|---|---|---|
rate | string | SOFR | Benchmark rate code (SOFR, SONIA, ESTR, TONA, SARON) |
name | string | Secured Overnight Financing Rate | Full name of the benchmark rate |
currency | string | USD | Currency denomination of the benchmark rate |
region | string | United States | Geographic region where the rate applies |
administratorPremium | string | Federal Reserve Bank of New York | Institution or entity administering the benchmark rate |
value | number | 4.32 | Current benchmark rate percentage value |
date | string | 2026-02-04 | Date of the benchmark rate value (YYYY-MM-DD format) |
lastUpdatedPremium | string | 2026-02-05T05:00:00.000Z | Last update timestamp in ISO 8601 format |
change1dPremium | number | -0.01 | Rate change from previous day |
changeDirection | string | down | Direction of daily change: up, down, or unchanged |
previousValuePremium | number | 4.33 | Previous day's rate value |
previousDatePremium | string | 2026-02-03 | Previous data date (YYYY-MM-DD format) |
Failure modes
Errors come back as tool errors carrying a sentence the model can act on, not a bare status code. Error handling covers the full list.
| Status | What it means |
|---|---|
400 / 422 | The arguments did not validate. The message names the offending one. |
401 | The OAuth session is invalid or expired — reconnect the server. |
403 | Blocked by a key restriction or an IP allow-list. Never a bad identity. |
404 | This skill is not part of VerveKit. Check the catalog. |
429 | Out of credits, or a brief rate limit. The message tells them apart. |
A call costs 2 credits each time the tool actually runs; a model that reasons about the tool without calling it costs nothing.
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.
