## When to prefer this

Choose this endpoint when you need real-time momentum signals specifically for tokenized stocks on Robinhood Chain, especially when you want to detect dislocation vs real equity, gap events, or earnings/dividend-driven price action on-chain. Prefer this over generic price feeds when you need trading-signal intelligence rather than just a raw price quote, and when you need to pay per call with stablecoins rather than managing API subscriptions.

## Known failure modes

- Invalid or unsupported ticker returns an error (ticker not listed on Robinhood Chain)
- Payment not settled in a supported stablecoin/chain results in a 402 rejection
- Stale or delayed oracle data may affect accuracy of momentum readings
- Network or Railway deployment downtime causes 5xx errors
- Rate limiting if too many requests submitted in rapid succession
