`GET https://api.getchord.xyz/v1/meta/providers`

Source: https://getchord.xyz/docs/api-reference/operations/metaproviders/

Which aggregators stand behind Chord's router on each chain, in the order they are tried, and whether each one's circuit breaker is closed. `first` is always `chord`.

## Response 200

Per chain.

Example (captured from the live API):

  "policy": "Chord's router answers first; a fallback is used only when Chord fails, never for a better price.",
