Endpoint cost map

Price the heavy routes first. That is where the real budget moves.

Budgeting rules

Budget the heaviest loop first, then add the convenience routes around it.

Loop budget

Budget the heavy loop first

History, order flow, and deep-book pulls move the bill. Price those before the convenience routes.

Venue premium

Treat Lighter history as its own line item

Lighter order book history costs 10 credits per request, so it should not share the same budget model as Hyperliquid.

Reality check

Model the mix before you ship it

A loop with 1,000 order books and 500 history pulls is already 3,500 credits. Do the math before you automate.

Where the budget changes

These are the exceptions that usually change the budget after the first pass.

Lighter.xyz

High detail, higher credit cost

Checkpoint-to-tick reconstruction stays plan-gated, and order book history remains the expensive outlier.

HIP-3

Builder-perp breadth is plan-gated

Free still includes km:US500. Build+ opens the wider builder-perp family under the Hyperliquid namespace.

WebSocket

Streaming is usually cheaper than polling

Messages bill at 1 credit each, so live transport often beats frequent REST loops once the client is running.

What to confirm after pricing

Once the cost is clear, lock throughput and response shape.
