What should I bid
Priced tiers over a rolling 15m window.
Percentile history
Log scale, one point per block.
Block pressure
Compute units consumed against the per block ceiling.
Priority fees are a tax every Solana user pays blind. One honest number, free forever, no key, no rate limit worth mentioning.
This page reads two views. The engine underneath maintains hundreds more, incrementally, and lets you subscribe to any of them.
The number in the hero, the JSON-RPC response your bot polls, and the websocket it subscribes to are the same view at three scopes.
Start Building With Raptor
The same JSON-RPC methods and params over HTTP, WebSocket, and Yellowstone gRPC.
Percentiles are recomputed as each block lands, not averaged across a polling window.
Every response carries block-fill percentage and fee volatility alongside the price.
Six percentile-based bids, each with its landing probability and expected block position.
100 requests/min on the free tier. Signup to first response in under a minute.
Subscribing sends the current values first, then every insert, update, and delete as a full row.
Free tier: 100 req/min. No credit card required.
