Markets

Every pair is quoted against USDC, both ways. The table reads GET /levels and GET /config from the staging gateway every 10 seconds; it is the same data your integration gets.

How to read it

Column	Meaning
Reference	The mid-market rate the makers price from, in USD per coin: the pair’s Chainlink FX feed on Base, with the time of its last update.
Spread	Distance of the firm quote’s price from the reference, in basis points, for buying the coin with USDC and for selling it. It is the whole cost of the trade besides gas: there is no protocol fee (Fees and pricing).
You buy / you sell the coin	The largest firm quote available right now in that direction, as the USDC amount and the coin amount. A request above it answers `400 over-size`. A dash with a reason means the direction is not quoted at this moment: maker funding (the maker’s balance or allowance cannot cover a trade), no reference price, paused.

A quote at or below the size shown fills at exactly the quoted amounts or reverts: no slippage, no last look. Sizes move as fills happen and as makers rebalance, so read them from /levels at runtime rather than copying them. Quotes are available 24/7; which directions are quoted at a given moment depends on the makers’ inventory and reference prices.

Need a size that must always be available, or a pair not listed here? Write to hello@aile.tech with the corridor, expected daily volume and ticket sizes. See Liquidity and capacity.

The same data by API

curl -s https://staging.app.aile.tech/api/base/v1/levels | jq '.levels[] | {sellToken, buyToken, firmQuoted, maxFirmSize, reference, reason}'

No key is needed. The answer is cacheable for a few seconds; the machine-readable form is documented at GET /v1/levels.
