Why read Waxpeer through this API

Waxpeer is a P2P venue with instant delivery, and its asks tend to sit between Buff163 and Steam — useful as a sanity check when two markets disagree.

Waxpeer covers both CS2 and Rust and quotes Doppler phases on a subset of knives. We take the lowest ask and the listing count every five minutes.

The point of a single API is that you are not maintaining 8 integrations. Waxpeer arrives in the same shape as every other market: minor units, a currency, a listing count and a capture timestamp. Switch ?currency=EUR and every market converts together.

What you get for each Waxpeer item

Example: Waxpeer in a cross-market response

One request returns every market's live price for an item. Prices below were true when this page was built:

curl "https://steamdataapi.com/api/v1/items/AK-47%20%7C%20Redline%20(Field-Tested)/markets" \
  -H "Authorization: Bearer sdk_YOUR_KEY"
{
  "currency": "USD",
  "best": { "market": "csfloat", "price": 2871 },
  "spread": 297,
  "markets": [
    { "market": "csfloat", "price": 2871, "quantity": 3450, "capturedAt": "2026-07-30T11:40:02Z" },
    { "market": "buff163", "price": 2871, "quantity": 10589, "capturedAt": "2026-07-30T11:40:06Z" },
    { "market": "youpin", "price": 2926, "quantity": 10000, "capturedAt": "2026-07-30T11:40:06Z" },
    { "market": "c5game", "price": 2971, "quantity": 2428, "capturedAt": "2026-07-30T11:40:06Z" },
    { "market": "skinport", "price": 3015, "quantity": 559, "capturedAt": "2026-07-30T11:40:06Z" }
  ]
}

At build time Waxpeer was asking $31.68 for that item with 1,112 listings, against $28.71 at the cheapest venue (csfloat). That gap is exactly what the best and spread fields hand you without comparing anything yourself.

Tracking Waxpeer prices over time

A single ask tells you today; a series tells you whether today is unusual. Every market accrues a daily lowest-ask point, so you can pull Waxpeer's own history and compare it against Steam's median-sale series — which reaches back to 2013-08-13 and totals 15,581,753 daily points across the catalog.

curl "https://steamdataapi.com/api/v1/items/AK-47%20%7C%20Redline%20(Field-Tested)/history?source=markets&days=90" \
  -H "Authorization: Bearer sdk_YOUR_KEY"

The two series answer different questions. Steam's median is what items actually sold for, which lags but cannot be moved by one optimistic listing. Waxpeer's daily low is what you could have bought at. Traders generally want both: the sale price to value a position, the ask to act on one.

From a Waxpeer price to a portfolio total

The same prices drive inventory valuation. Give the inventory endpoint a public SteamID and every item comes back priced — at the Steam ask and at cross-market real value, with Waxpeer included in the comparison — plus float, paint seed and Doppler phase where they apply, and a portfolio total in your currency.

const res = await fetch(
  "https://steamdataapi.com/api/v1/inventory/76561198000000000?game=cs2&currency=EUR",
  { headers: { Authorization: "Bearer sdk_YOUR_KEY" } },
);
const { totalValue, items } = await res.json();

Waxpeer versus the other markets we read

Item coverage differs a lot by venue. These counts are live from our own catalog:

Steam itself is the ninth source: 29,458 CS2 and 5,397 Rust items carry a Steam ask, with median-sale history back to 2013 — 15,581,753 daily points in total.

Frequently asked questions

Does the Waxpeer API cover Rust as well as CS2?

Yes. We currently price 22,359 CS2 items and 4,776 Rust items from Waxpeer. Pass ?game=rust to filter.

How fresh are Waxpeer prices?

Waxpeer is re-read every 5 minutes. Every price carries a capturedAt timestamp so you can see exactly how old it is rather than guessing.

Do I get Waxpeer prices for Doppler phases?

Yes — Waxpeer quotes phases per listing, and we hold 474 phase prices across 107 knives from it. Ruby, Sapphire, Black Pearl, Emerald and Phase 1–4 are priced separately.

Can I get historical Waxpeer prices?

Yes. Every market accrues a daily lowest-ask series, so /history?source=markets returns Waxpeer's day-by-day price next to the others. Steam's median-sale series reaches back to 2013-08-13 and is on the same endpoint with ?source=steam.

What happens when Waxpeer stops listing an item?

It drops out of that item's markets array once its last capture ages past seven days, rather than showing a price nobody is offering. The cross-market real value keeps its last known figure, so a delisting does not turn your valuations into nulls.

Is this an official API?

No. This is an independent API that reads public marketplace data and serves it in one normalised shape. We are not affiliated with Waxpeer, Valve or Steam.
