# Function: createRemoteJWKSet

▸ **createRemoteJWKSet**(`url`, `options?`): [`GetKeyFunction`](../interfaces/types.GetKeyFunction.md)<[`JWSHeaderParameters`](../interfaces/types.JWSHeaderParameters.md), [`FlattenedJWSInput`](../interfaces/types.FlattenedJWSInput.md)\>

Returns a function that resolves to a key object downloaded from a
remote endpoint returning a JSON Web Key Set, that is, for example,
an OAuth 2.0 or OIDC jwks_uri. Only a single public key must match
the selection process.
The JSON Web Key Set is fetched when no key matches the selection
process but only as frequently as the `cooldownDuration` option allows,
to prevent abuse.

**`example`** Usage
```js
const JWKS = jose.createRemoteJWKSet(new URL('https://www.googleapis.com/oauth2/v3/certs'))

const { payload, protectedHeader } = await jose.jwtVerify(jwt, JWKS, {
  issuer: 'urn:example:issuer',
  audience: 'urn:example:audience'
})
console.log(protectedHeader)
console.log(payload)
```
