# GetGovernmentYieldCurve

`GET /api/economic/v1/get-government-yield-curve`

## Request

- Base URL: `https://api.worldmonitor.app`
- URL: `https://api.worldmonitor.app/api/economic/v1/get-government-yield-curve`
- Auth: one of:
  - API key in header `X-WorldMonitor-Key`
  - API key in header `X-Api-Key`

GetGovernmentYieldCurve returns one sovereign market's daily yield curve from its official national publisher, or the OECD monthly 10Y benchmark when no daily curve is covered. Yields keep their publisher's measure and are never converted.

## Query parameters

- `country` string, required
- `history` boolean
- `limit` integer
- `jmespath` string

## Response `200`

OK

- WorldmonitorEconomicV1GetGovernmentYieldCurveResponse: GetGovernmentYieldCurveResponse is the curve for the requested market.
  - `country` string: Echoed uppercase ISO 3166-1 alpha-2 code.
  - `source` string: Covered-market descriptor, e.g. "jp-mof-cmt" or "uk-boe-spot".
  - `measure` string: Yield measure: "par", "spot", "benchmark", or "monthly-10y".
  - `curves` WorldmonitorEconomicV1YieldCurvePoint[]
    - `date` integer: Warning: Values > 2^53 may lose precision in JavaScript
    - `tenors` object: Yield per tenor, in percent, as published (never converted between measures).
  - `unavailable` boolean: True when the market is uncovered or its seeded curve is unavailable. An empty curves list is graceful degradation, not a confirmed zero yield.

## Other responses

- `400`: Validation error
- `401`: Missing or invalid API key.
- `403`: API access requires an active subscription (the API key's subscription is inactive or expired).
- `429`: Rate limit exceeded.
- `503`: Service unavailable. Billing-verification responses include code and X-Billing-Verification; other gateway infrastructure failures use the generic GatewayError shape.
- `default`: Gateway or handler error response.
