# Reference rates

> The oracle's band for each corridor, and every source it is made of.

The band is advisory. It is the median of public NGN/USD sources, recomputed every 10 seconds, published
to nodes as a sanity check and shown to takers next to each quote. It never sets a price.

<ResponseField name="bands" type="object[]">
  `{ base, quote, mid, low, high, sources, at }` per corridor. `mid`, `low` and `high` are naira per dollar.
  `sources` is how many sources made the band. `at` is unix milliseconds.
</ResponseField>

<ResponseField name="sources" type="object[]">
  Every source the oracle polls: `{ name, value, bid, ask, ageSeconds }`. `bid` and `ask` are null for a
  source that publishes one number.
</ResponseField>

<ResponseField name="unavailable" type="string[]">Sources that are failing right now.</ResponseField>
