Early access is open

One key, one schema, four asset classes. Ask for access and a human reads the request — no autoresponder, no drip sequence.

LIAW is open for early access. The feed has been live for a while; the door is what changed. It is still invite-only — you ask, a person reads it, and you get a key.

What it is

One read-only REST API over crypto, equities, FX and commodities. It is asset-first: you ask for BTC quoted in USD, and LIAW resolves which venues and which instruments stand behind that number.

BASH
curl "https://api.getliaw.com/v1/prices/latest?assets=BTC,AAPL,EUR&quote=USD" \
  -H "Authorization: Bearer $LIAW_KEY"

The surface is deliberately small: /v1/assets to discover what exists, /v1/prices/latest for the current mark, /v1/prices/ohlcv for history. AAPL and BTC come back through the same shape, because an asset is an asset — only asset_class differs.

Why it is built this way

Market data is usually fragmented by asset class — crypto in one API, FX in another, equities behind a third contract with its own identifiers, its own rate-limit arithmetic and its own idea of what a price is. Then it arrives padded with long-tail metadata nobody asked for.

We answer one question instead: what is the price and liquidity situation of this asset, right now. Everything else is opt-in.

That includes provenance. A bare number never says where it came from, so source ships as a field rather than as a footnote: how many venues stand behind the price, and how far apart they are in basis points. It is not a verdict. We publish what we know about a mark; what counts as good enough stays the caller's call.

What early access gets you

  • One key, one schema, one invoice across every asset class we cover.
  • Limits you can read. Requests per minute and a monthly allowance, both reported in the headers of every response — no credit formula to reverse engineer before you can size a plan.
  • A contract that cannot drift. The reference is generated from the API code and published as OpenAPI 3.1, so the docs and the server are the same artifact.
  • A short line to us. Early access means your questions reach the people writing the ingestion workers, and your use case can still change the roadmap.

How to get in

Start free with a work email and mint a key from the dashboard. Telling us what you are building helps, but it is not required — asking a stranger to justify themselves before they have seen a key is friction nobody needs.

Questions reach the people writing the ingestion workers at access@liaw.dev.
