quote → assemble workflow over that desk: you request a
price for a pair, receive a firm pathId, and assemble a transaction you sign yourself.
Astrolabe never holds your keys.
assemble returns a base64 VersionedTransaction that you
sign as userAddr and submit through your own RPC.The two ways in
This API (programmatic)
POST /sor/quote/v3 → POST /sor/assemble. Best when you want an explicit quote object,
a firm pathId, and a transaction you assemble and sign yourself.Jupiter / aggregators (on-chain)
Users routed through Jupiter Metis hit the PropAMM directly on-chain — no API call needed.
The desk posts the same quotes both paths read.
What it prices
The PropAMM is pair-agnostic: each currency pair is its own on-chain market with its own inventory andQuoteState, so new pairs are added without an API change. Query
GET /info/tokens/101 for the pairs quotable right now rather than hard-coding this table.
A second source,
astrolabe-partner-rfq, is reserved for firm partner inventory and is parked
in v1 — its endpoints return 501.
Size-aware pricing
The PropAMM posts a tiered quote: small clips are priced tight (matching deep pools), larger clips are priced wider where those pools slip. Each quote response reports which tier priced it (astrolabe.tier). A clip larger than the top tier is rejected, not clamped — so
an assembled transaction always reflects a fill the chain will actually settle.
