# Get NBBO for all symbols

`GET /v1/quotes`

Returns NBBO + per-venue BBO for every symbol with valid quotes. Optional `?symbols=A,B,C` filter restricts to a comma-separated allow-list.

## Query parameters

- `symbols` string

## Response `200`

All quotes

- AllQuotesResponse
  - `quotes` AllQuoteEntry[], required
    - `nbbo` QuoteNbbo, required
      - `age_ms` integer — Age of the NBBO in milliseconds — min `age_ms` across the venues whose bid+ask were chosen for this NBBO. Lets callers refuse trades on quotes older than their tolerance instead of having to walk the per-venue `venues.{v}.age_ms` map themselves.
      - `ask` number, double, required
      - `bid` number, double, required
      - `mid` number, double, required
      - `spread_bps` number, double, required
      - `staleness` string, required — Discrete staleness class derived from `age_ms`. Trip-wire for trading code: never act on `dead`, prefer not to act on `stale`. `fresh` — < 1 s (real-time, kernel-bus origin) `recent` — < 10 s (acceptable for non-latency-sensitive use) `stale` — < 60 s (probable edge-side feed stall, refresh first) `dead` — ≥ 60 s (do not trade — feed is presumed broken)
    - `symbol` string, required
    - `venues` object, required
