Treasures Finance — B2B Public API
Public B2B API for tokenized stock discovery, quoting and trade execution, USDC bridging across Solana and Ethereum, and portfolio + trade history reads.
Wire format. All token amounts, USDC amounts, shares, prices and bps-derived
decimals are JSON strings to avoid float drift. Integer fields
(expires_at, *_bps, quote_index, timestamps in seconds) are JSON numbers.
Auth. Only POST /quote/buy, POST /quote/sell and POST /bridge/quote
require ownership_proof (wallet-key signature over a canonical challenge —
see OwnershipProof). POST /trade/submit is gated by the per-leg signed
payload itself; everything else is unauthenticated.
Rate limits. Per-IP and per-(IP, wallet) sliding windows backed by Redis.
Upstream 429s propagate as 502 provider_unavailable.
