API reference

Metadata

Normalized per-exchange reference data — leverage caps, contract limits, funding, volume, deposit/withdraw and orderbook stats.

Metadata is sourced from cexfeeds and normalized across venues, so the same shape works everywhere. This is the lowest-tier surface — available to every key — because it's reference data, not signal.

`{kind}` is one of `limits`, `funding`, `volume`, `assets`, `orderbook`. `{exchange}` is the lowercase exchange id.

GET {exchange}

Normalized metadata of the given kind for one exchange.

GET/v1/meta/{kind}/{exchange}

Tier: machine-dev+ (all tiers)

Payloads are curated — only the fields below are exposed. New upstream fields never leak by default (allowlist policy). Every response carries a per-consumer trace watermark.
