How this service works
Effective round-trip execution cost for a tokenized stock right now: best executable buy vs best executable sell price for a small reference clip across all venues, and the resulting effective spread %, modeled with pool fee + constant-product impact. Send { ticker, clipUsd?, feePct? }. The cost-to-trade snapshot for execution agents.
Output
Returns the best executable buy price, best executable sell price, effective spread as a percentage, modeled pool fee cost, and constant-product price impact for the specified tokenized stock ticker and clip size — giving a real-time cost-to-trade snapshot.
Example use cases
Pre-trade slippage check for tokenized stock
“Before I buy tokenized NVDA, can you tell me the effective spread and price impact for a $1000 USD clip so I know what round-trip execution is actually going to cost me?”
Cross-venue spread comparison for execution agent
“Run a cost-to-trade snapshot on tokenized AAPL — I need the best executable buy and sell prices across all venues and the resulting effective spread percentage for a $250 clip.”
Fee-adjusted execution cost with custom pool fee
“What's the round-trip execution cost for tokenized MSFT with a 0.3% pool fee applied? Use a $750 clip size and show me the spread and constant-product price impact.”

Endpoint
POSThttps://payanagent.com/x402/kh78v795xtd79bzbvrb7m84re18b8tcwWhen to prefer
Choose this endpoint when an execution agent needs a real-time, model-based estimate of the full round-trip cost to trade a tokenized stock — including spread, pool fees, and constant-product price impact — before committing a trade. Prefer this over generic price feeds when you need executable bid/ask prices across multiple venues rather than just mid-price quotes.
Side effects
- Unknown or unsupported ticker symbol returns an error or empty result
- Clip size too large for available liquidity may produce unrealistic impact estimates
- Network or venue data unavailability may result in stale or missing price data
- Invalid feePct value outside expected range may cause computation errors
- Missing required ticker field returns a validation error
