Interest rates - Conduit

The rates family is Conduit’s interest-rate factor set: the short end (policy and money-market rates), the long end (10-year government bond yields), and a curve measure (the 10Y-3M spread), each with a stable canonical indicator ID that means the same thing in every country. Query the UK policy rate, the US 10-year yield, and a country’s curve spread with the same slugs and filters, and join across countries cleanly. This page leads with the rate series that are available and their units, then shows how to read them through the two observation endpoints.

What data is available

The rates family holds 32 series across the covered countries. Four canonical rate series make up the set, one per country where it exists:

Policy Rate

The central bank’s headline policy rate. Unit: percent.

3-Month Money-Market Benchmark Rate

The short-end money-market benchmark. Unit: percent.

10-Year Government Bond Yield

The 10-year sovereign benchmark yield. Unit: percent.

10Y-3M Yield-Curve Spread

The slope of the curve: 10-year yield minus the 3-month rate. Unit: percentage_points.

The 32-series total spans these four shapes across countries; the exact per-country availability is live, so treat this as a map and read the authoritative, machine-readable list from GET /v1/canonical-indicators and the breadth summary from GET /v1/public/coverage.

Units

Rate series carry an explicit unit. Two units appear in this family, and branching on unit matters because levels and spreads are not the same thing:

percent

Rate levels: Policy Rate, 3-Month Money-Market Benchmark Rate, 10-Year Government Bond Yield. A value of 4.5 means 4.5 percent.

percentage_points

Differences between two rates: the 10Y-3M Yield-Curve Spread. A value of -0.4 means the 10-year yield is 0.4 percentage points below the 3-month rate (an inverted curve).

A percent value is a level you can read directly. A percentage_points value is a gap: it can be negative when the curve is inverted (short rates above long rates). Do not treat the two units as interchangeable.

Country coverage

Rate series are keyed by ISO 3166-1 alpha-3 country code, drawn from the same 35-country macro universe:

ARE AUS BRA CAN CHE CHL CHN CZE DEU DNK EMU ESP EUR FRA GBR
HKG IDN IND ISR ITA JPN KOR MEX NLD NOR NZL POL QAT SAU SGP
SWE THA TUR USA ZAF

Coverage is not uniform: not every country carries all four rate series, which is why the family totals 32 series rather than four times the country count. Confirm exactly which rate series a country carries with GET /v1/public/coverage and resolve the live indicator universe with GET /v1/canonical-indicators.

These are rate and yield series sourced from institutions of record. Conduit does not sell raw vendor or real-time market price-tick data: it is redistribution-blocked and deliberately not part of the product. There is no FX-rate indicator family.

Canonical indicator IDs

Each rate series has a canonical indicator ID, a stable slug identical across countries, returned on every observation as indicatorId. You query by it and join on it. The complete, current list of rate indicator IDs (with names, families, and units) is served live:

curl -s "https://data.quantoraresearch.com/v1/canonical-indicators" \
  -H "x-api-key: $CONDUIT_API_KEY"

Use GET /v1/canonical-indicators to confirm the exact rate slug for the country you want before building queries. Conduit fails closed on unknown query parameters and rejects unrecognized indicators with bad_request.

Querying the data

Rate values are served as observations, the same as every other macro factor. An observation is a single value a series describes for a single period, for example the US 10-year government bond yield on a given day. Two public endpoints cover the two shapes you need: a time series, and the latest value per indicator.

GET /v1/public/observations

The history. Time series of public rate observations across periods and vintages. Cursor-paginated.

GET /v1/public/observations/latest

The snapshot. The single latest public reading per rate indicator. The fastest way to ask “where are rates now.”

Both endpoints go to https://data.quantoraresearch.com, require a key with the data:read scope, and send the key in the x-api-key header (or Authorization: Bearer). They share one filter set and one response shape.

Authentication

-H "x-api-key: $CONDUIT_API_KEY"

A data:read scope is required. See Authentication.

Filters

Both endpoints accept the same filters. Combine them freely; they are AND-ed. Unknown query parameters are rejected with bad_request (Conduit fails closed).

country

string

ISO 3166-1 alpha-3 country code, for example USA, GBR, DEU. One of the covered countries.

indicator

string

Canonical rate indicator slug. Also accepted as indicator_id. Omit it to pull a country’s full set of latest readings in one query, then keep the rate series by matching each row’s indicatorId against the rate indicator IDs from /v1/canonical-indicators (where category is rates).

frequency

string

Publication cadence: daily, weekly, monthly, quarterly, or annual.

freshness

string

Keep only readings with a given freshness label: fresh, stale, or unknown. The label is set by a per-frequency age gate, independent of any source self-report.

source_id

string

Conduit source id. Filter to a single institution of record.

provider_id

string

Conduit provider id or name. Also accepted as provider.

Time filters run on two axes (period: what a value describes; knowledge-time: when it became known):

period

string

Convenience filter on the described period: YYYY, YYYY-MM, or YYYY-Qn.

period_end

string

Upper bound on the described period (YYYY-MM-DD).

start_date

string

Lower bound on knowledge-time (observed_at).

end_date

string

Upper bound on knowledge-time (observed_at).

as_of

string

Returns the latest vintage known on or before a timestamp. See the caveat below.

limit

integer

Page size, 1 to 500. Defaults to 100. Follow meta.pagination.next_cursor with cursor while has_more is true. sort and order (asc, desc) control ordering.

as_of currently approximates the ingestion timestamp, not full provider-vintage reconstruction. Revisions are retained and never overwritten, so the revision history is visible, but reconstructing the exact value a provider had published at an arbitrary past instant is future work. Read as_of as “what Conduit knew by this time.”

Response fields

Public observations come back in camelCase. The fields most relevant to rate series:

observationId

string

Stable ID for this observation. Pass it to GET /v1/provenance/observations/{observationId} for the full source chain.

indicatorId

string

Canonical rate indicator slug. Use it to query and join across countries.

indicatorName

string

Human-readable indicator name, for example 10-Year Government Bond Yield.

country

string

ISO 3166-1 alpha-3 country code.

actual

number

The headline numeric value. A rate level (in percent) or a spread (in percentage_points), per unit.

unit

string

percent for rate levels, percentage_points for the curve spread.

period

string

Label for the period the value describes, for example 2026-06-10.

periodEnd

string

End of the described period (YYYY-MM-DD).

frequency

string

Publication cadence.

observedAt

string

Knowledge-time: the point at which the value is observed.

freshnessStatus

string

Freshness label: fresh, stale, or unknown.

provider

string

The provider name behind the source, for example Bank of England.

sourceUrl

string

The official source URL for the series.

rawAvailable

boolean

Whether a raw payload reference is exposed for this observation through the provenance endpoint.

Examples

A country’s full rates set (latest)

Pull every rate series Conduit holds for one country in a single latest call, then keep the rates family. Because /v1/public/observations/latest returns the latest reading per canonical indicator, one country query gives you the policy rate, the money-market benchmark, the 10-year yield, and the curve spread together.

curl -s "https://data.quantoraresearch.com/v1/public/observations/latest?country=USA" \
  -H "x-api-key: $CONDUIT_API_KEY"

A latest rates response looks like this:

{
  "data": [
    {
      "observationId": "obs_us_policy_rate_2026_06_10",
      "indicatorId": "policy_rate",
      "indicatorName": "Policy Rate",
      "country": "USA",
      "actual": 4.5,
      "unit": "percent",
      "period": "2026-06-10",
      "periodEnd": "2026-06-10",
      "frequency": "daily",
      "observedAt": "2026-06-10T00:00:00Z",
      "freshnessStatus": "fresh",
      "provider": "Federal Reserve (via FRED)",
      "sourceUrl": "https://fred.stlouisfed.org/",
      "rawAvailable": false
    },
    {
      "observationId": "obs_us_govt_bond_yield_10y_2026_06_10",
      "indicatorId": "govt_bond_yield_10y",
      "indicatorName": "10-Year Government Bond Yield",
      "country": "USA",
      "actual": 4.1,
      "unit": "percent",
      "period": "2026-06-10",
      "periodEnd": "2026-06-10",
      "frequency": "daily",
      "observedAt": "2026-06-10T00:00:00Z",
      "freshnessStatus": "fresh",
      "provider": "Federal Reserve (via FRED)",
      "sourceUrl": "https://fred.stlouisfed.org/",
      "rawAvailable": false
    }
  ],
  "meta": {
    "request_id": "a1b2...",
    "requestId": "a1b2...",
    "api_version": "v1",
    "pagination": { "limit": 100, "cursor": null, "next_cursor": null, "has_more": false }
  },
  "requestId": "a1b2..."
}

The indicatorId values above (policy_rate, govt_bond_yield_10y) illustrate the shape of a rate slug. Confirm the exact IDs from GET /v1/canonical-indicators for the country you query.

10-year yield history

Pull the time series of a country’s 10-year government bond yield, oldest first.

curl -s "https://data.quantoraresearch.com/v1/public/observations?country=USA&indicator=govt_bond_yield_10y&period=2025&order=asc&limit=500" \
  -H "x-api-key: $CONDUIT_API_KEY"

The curve-spread series

The 10Y-3M Yield-Curve Spread is a first-class series in percentage_points: read it directly rather than computing it. A negative value means an inverted curve (short rates above long rates).

curl -s "https://data.quantoraresearch.com/v1/public/observations/latest?country=USA&indicator=yield_curve_spread_10y_3m" \
  -H "x-api-key: $CONDUIT_API_KEY"

Conduit also serves stored rates analytics (curve spreads and more) as derived indicators, where each derived value records its input observation IDs and source refs. See Derived analytics.

Provenance

Every rate value traces back to an official release. Pass an observationId to the provenance endpoint for the named source, source URL, raw payload reference metadata, and the ingestion run.

curl -s "https://data.quantoraresearch.com/v1/provenance/observations/obs_us_policy_rate_2026_06_10" \
  -H "x-api-key: $CONDUIT_API_KEY"

Rate series draw on institutions of record, including FRED, ECB, BIS, Bank of England, and Bank of Japan, across roughly 97 source connectors.

Errors

Non-2xx responses share the standard envelope with a stable, machine-readable code.

Code	Status	Meaning
`bad_request`	400	Malformed query, an unknown query parameter, or an unrecognized indicator.
`unauthorized`	401	Missing or invalid API key.
`forbidden`	403	Key lacks the `data:read` scope.
`not_found`	404	Resource does not exist.
`rate_limited`	429	Rate limit exceeded; see `details`.
`internal_error`	500	Unexpected server error.

Macro indicators

Inflation, labor, growth, housing, external, income, and consumption factors.

Derived analytics

Stored rates analytics, curve spreads, and other derived indicators with input provenance.

Macro observations

The full observation surface, both time axes, and incremental sync.

Coverage
