Descripción

area:pricing difficulty:intermediate epic:analytics help wanted points:150 Stellar Wave
Background

The depth endpoint takes one amount. The question traders and treasuries actually ask is the shape: what does 100, 1,000, 10,000 cost me, and where does it stop being worth it.

What to build
  • GET /impact/:assetA/:assetB returning slippage at a ladder of sizes, in one call.
  • The ladder adapts to the pair's liquidity rather than being fixed, so a thin pair is not described entirely in sizes it cannot fill.
  • Name the size at which slippage crosses configurable thresholds — that single number is what most callers want.
Acceptance criteria
  • Slippage at a ladder of sizes in one response
  • The ladder adapts to available liquidity
  • Threshold crossings are reported explicitly
  • A pair too thin for the smallest size says so rather than returning 100%

Repo: Divinity-Labs/Lens. Node + Fastify + Prisma + Postgres. Tests are vitest (npm test), not jest — jest against this repo fails every file and tells you nothing.

?network= is not optional on a new route. Every row carries a network and the indexes lead with it. Read req.network ?? activeNetwork, filter on it, echo it in the response, and declare the parameter in openapi.yaml. tests/openapi.test.ts boots the server and fails if a registered route is missing from the spec.

A number without provenance is not an answer. Every figure this batch adds must carry what it was computed from: which venues, how many samples, how fresh. The point of Lens is that its numbers can be checked.

Never elide a contract id or an issuer. Take addresses from the protocol's own documentation and write them whole. A sibling repo's issue wrote CD2W5LUR…XZ4L and five contributors invented plausible contract ids to fill the gap.

Say when you cannot answer. An asset with no liquidity, a pair with one venue, a window with a gap — each has an honest answer that is not zero and not a 500. Zero is a number people act on.
