Current pricing levels for all pairs.

Invalid request input.

Missing or invalid Bearer token. The body is the same flat JSON error object used by all error responses.

No levels for the requested filter. Only returned for a single-pair lookup — symbol, or chain_id+base_token+quote_token together — that matches no currently-quotable pair. Broad reads never 404: an unfiltered request and a chain_id-only per-chain enumeration both return 200 with an empty pairs array, because a transient depth gap is not a client error. A genuine pricing outage is reported as 503.

Market, route, provider, or runtime dependency unavailable.
