# Rates

> Cached FX rates for supported Solana stablecoin pairs.

Rates power swap quoting. RemitFlex caches prices and refreshes them in the background — rate reads are served from cache for low latency.

**Required scope:** `fx:read`

## All rates

```bash theme={null}
curl https://api.remitflex.io/v1/rates \
  -H "Authorization: Bearer $REMITFLEX_API_KEY"
```

## Single pair

```bash theme={null}
curl https://api.remitflex.io/v1/rates/USDC/EURC \
  -H "Authorization: Bearer $REMITFLEX_API_KEY"
```

Returns `503` if the pair is not cached yet — retry after a few seconds.

## Supported pairs

```bash theme={null}
curl https://api.remitflex.io/v1/rates/currencies \
  -H "Authorization: Bearer $REMITFLEX_API_KEY"
```

Use `data.pairs` when validating swap requests before calling `POST /v1/swaps`.
