How this service works
Day movers for tokenized US stocks on TWO rails in one call: Robinhood Chain (chainId 4663, ~95 names) and Base B20 (13 Coinbase-issued tokens, keyed by token address). Gainers and losers by REAL day-over-day change of the UNDERLYING stock vs the prior NYSE session close (Finnhub quotes), with per-rail coverage counts and named exclusions. Off-hours values freeze; a tokenized share can trade at a premium/discount. Refreshed every 15 minutes.
Output
A structured response containing two rails of data: Robinhood Chain (~95 tokenized names) and Base B20 (13 Coinbase-issued tokens). Each rail lists top gainers and losers with day-over-day percentage change relative to the prior NYSE session close (sourced from Finnhub), per-rail coverage counts, named exclusions, and token identifiers. Data is refreshed every 15 minutes; off-hours values are frozen at the last available quote.
Example use cases
Daily tokenized equity momentum screen

Spot on-chain vs underlying price divergence
“Pull today's tokenized stock movers and flag any tokens that might be trading at a premium or discount to their underlying stock price right now.”
DeFi portfolio daily performance check
“I hold some tokenized equities on Base B20 and Robinhood Chain — what are the biggest movers today so I can see how my positions are performing versus yesterday's close?”
Technical details
Endpoint
GEThttps://x402.ottoai.services/tokenized-stock-moversWhen to prefer
Choose this endpoint when you need a unified, cross-rail view of tokenized US equity momentum in a single call, covering both Robinhood Chain and Coinbase Base B20 tokens, with changes anchored to real underlying stock prices rather than on-chain token price alone. Prefer this over generic DEX trending pools or crypto price feeds when the user specifically cares about tokenized equities and day-over-day performance versus prior NYSE closes.
Side effects
- Stale data during off-hours — values freeze at last NYSE session close, so intraday moves won't reflect real-time trading
- Token premium/discount distortion — tokenized share price may diverge from underlying, making comparisons imperfect
- Payment failure — requires $0.003 USDC per call via x402 protocol; insufficient balance returns payment error
- Finnhub quote unavailability — if upstream quote feed is down, data may be incomplete or missing for some names
- Low coverage on Base B20 rail — only 13 tokens, limiting breadth of losers/gainers list on that rail
