PriceLevels ​

Entry point for Titan's pAMM price levels. Wraps a snapshot source and exposes quote helpers, mirroring the structure of PropAmmRouter.

Usage ​

python
from propamm.prices import PriceLevels, PriceLevelsWsSource

# one-shot HTTP snapshot (default)
prices = PriceLevels()
snapshot = await prices.get_price_levels()

# live stream
prices = PriceLevels(
    source=PriceLevelsWsSource(url="wss://eu.data.titanbuilder.xyz/ws/pamm_price_levels"),
)
snapshot = await prices.get_price_levels()
await prices.close()

Constructor ​

python
PriceLevels(
    source: PriceLevelsSource | None = None,
    *,
    rpc_url: str | None = None,
)

source (optional) ​

Source the snapshot is pulled from. Defaults to a PriceLevelsRpcSource. Pass a PriceLevelsWsSource for a live stream.

rpc_url (optional) ​

Titan JSON-RPC endpoint used by the quote helpers. Ignored when source is a PriceLevelsRpcSource (its URL is reused). Set this when pairing a PriceLevelsWsSource with a private or regional deployment so quotes go to the same host:

python
prices = PriceLevels(
    source=PriceLevelsWsSource(url="wss://us.data.titanbuilder.xyz/ws/pamm_price_levels"),
    rpc_url="https://us.data.titanbuilder.xyz",
)

Methods ​

get_price_levels() ​

python
async def get_price_levels() -> PriceLevelsSnapshot

Latest price-level snapshot from the configured source.

Returns PriceLevelsSnapshot.

get_quote() ​

python
async def get_quote(token_in: str, token_out: str, amount_in: int) -> TitanQuote

Best quote across all pAMMs for a size (titan_getPammQuote). Served from Titan's latest snapshot over HTTP, skipping the on-chain eth_call that router.quote runs.

Returns TitanQuote.

get_quote_venue() ​

python
async def get_quote_venue(venue: str, token_in: str, token_out: str, amount_in: int) -> TitanQuote

Quote from a specific venue for a size (titan_getPammQuoteVenue).

Returns TitanQuote.

close() ​

python
async def close() -> None

Tear down the snapshot source. Closes the stream socket when the source is a PriceLevelsWsSource; no-op for PriceLevelsRpcSource.
