v1.3.1

Sep 25, 2026Developer guides, runnable docs, and two new venues

NEW
DocsDeveloper guides at /resources: task-first guides for live prices, the cross-market best bid and ask, history, float and Doppler buckets, liquidity, and Rust, each with runnable curl, TypeScript, and Python and a Markdown twin.
IMPROVED
DocsAPI reference code samples are copy-paste runnable: real example items and required parameters filled in, syntax highlighting, copy buttons on code and responses, and Python samples that read the response body directly.
FIXED
DocsAPI reference accuracy pass: the cash-executable bid rule on pricing reads, liquidity venues and the insufficient-data badge, the full set of /v2 game routes, and refreshed response samples.
/v1/pricing/:marketHashName Reading prices: ask, bid & NBBO /v1/liquidity/:marketHashName Games: CS2 & Rust
NEW
Market dataYoupin (CS2) listings now feed cross-market pricing, NBBO, and depth.
/v1/pricing/:marketHashName /v1/nbbo /v1/nbbo/depth
NEW
Market dataRapidSkins stock feeds for CS2 and Rust.
/v1/pricing/:marketHashName Games: CS2 & Rust
NEW
Market dataCS.Deals Rust prices and sale averages.
Games: CS2 & Rust
IMPROVED
Market dataThe Rust catalog now includes items that are not currently listed anywhere, discovered from Steam item definitions, with their images mirrored.
/v1/items /v1/schema
FIXED
APIOrder-book depth only reports a crossed book when the crossing quotes come from supported cash venues.
/v1/nbbo/depth
IMPROVED
DocsOne changelog for the product and the API, filterable by area and type, with links from each API change to its reference page.

v1.3.0

Sep 14, 2026Rust joins the terminal and the API

NEW
APIRust in the developer API: game-scoped /v2 variants of pricing, listings, history, history by market, NBBO, depth, item search, liquidity, and item schema, each with a required game=cs2 or game=rust parameter. Same response shapes, auth, and quotas as v1, included in every plan. Rust history buckets carry bestAskCents and bestBidCents like CS2.
Games: CS2 & Rust /v1/pricing/:marketHashName /v1/pricing/:marketHashName/listings /v1/pricing/:marketHashName/history /v1/pricing/:marketHashName/history/markets /v1/nbbo /v1/nbbo/depth /v1/items /v1/liquidity/:marketHashName /v1/schema
NEW
APIMarket health per game: GET /v2/markets/health?game=rust, keyless like the v1 route.
/v1/markets/health
NEW
Market dataMannco.store prices for CS2 and Rust.
IMPROVED
DocsAPI docs readability pass: stronger heading and inline-code contrast, and response samples moved into the code rail next to the request runner.

v1.2.2

Aug 31, 2026Safer recommendations and Chinese API docs

IMPROVED
APIRecommendations withhold a hard price when supporting quotes are thin or unstable, and no longer count non-cash venues as support.
/v1/recommendations/:marketHashName
NEW
DocsAPI reference in Simplified Chinese at /zh-cn/api-docs, covering the introduction, authentication, rate limits, every concept guide, and the pricing and market-data endpoints.
Introduction
NEW
Market dataWhiteMarket buy orders are now ingested, adding a bid side for WhiteMarket to NBBO and depth.
/v1/nbbo /v1/nbbo/depth
FIXED
Market dataSteam Community Market order books ingest again after Steam changed its response format.
/v1/nbbo/depth
DEPRECATED
Market dataBitSkins is retired from the feed. It no longer appears in market lists or quotes, so drop bitskins from any markets filter.
/v1/markets/health

v1.2.1

Jul 30, 2026Cleaner top of book

IMPROVED
APIThe crossed flag now compares seller-net bids (after the selling venue's fees), so a bid that only looks crossed before fees is no longer flagged. Raw quotes are still served as-is.
/v1/nbbo
FIXED
Market dataBUFF float and fade bucket buy orders no longer leak into the base item's best bid.
/v1/nbbo /v1/pricing/:marketHashName
FIXED
API/v1/aggregations/min-prices returns one representative row per market.
/v1/aggregations/min-prices
NEW
APIMarket health adds freshnessCoveragePct per market: the share of that market's served prices refreshed within its expected cadence.
/v1/markets/health
NEW
APIHistory responses echo effectiveInterval, the bucket width actually served (10m, 1h, or 1d), which can differ from the interval you asked for.
/v1/pricing/:marketHashName/history /v1/pricing/:marketHashName/history/markets
FIXED
APICrossed books no longer produce negative spreads on pricing reads: spreadBps is null when the best bid exceeds the best ask, and the mid price falls back to the best ask. NBBO keeps its explicit crossed flag.
/v1/pricing/:marketHashName Reading prices: ask, bid & NBBO
IMPROVED
APIThe default best bid on pricing, item search, and recommendations is now cash-executable, matching NBBO. Pass an explicit markets list to consider every venue's bid.
/v1/pricing/:marketHashName /v1/items /v1/recommendations/:marketHashName
IMPROVED
Market dataSteam Community Market sales now feed liquidity scores.
/v1/liquidity/:marketHashName

v1.2.0

Jul 3, 2026Item schema API

NEW
APIGET /v1/schema: the full item catalog as one snapshot with collections, containers, variants, float ranges, images, and per-market catalog ids. Send If-None-Match with the last ETag to get a 304 when nothing changed.
/v1/schema
NEW
APIGET /v1/schema/items/:idOrName: single-item schema lookup by canonical id or market_hash_name.
/v1/schema/items/:idOrName
NEW
APIGET /v1/schema/changes: incremental catalog sync. Returns only items changed after your stored schemaVersion, cursor-paginated.
/v1/schema/changes
IMPROVED
APIItem images in the schema are served from the SkinPricer CDN.
/v1/schema

v1.1.0

Jun 24, 2026Liquidity API and the official TypeScript SDK

NEW
SDK@skinpricer/sdk on npm: a typed TypeScript client for every key-gated v1 endpoint with zero runtime dependencies, typed errors, retries, timeouts, and rate-limit metadata. 0.2.0 adds the execution-adjusted NBBO; 0.3.0 adds liquidity and market-health resources and marketHashNames lookups on aggregations.
Introduction
NEW
APIGET /v1/liquidity/:marketHashName and POST /v1/liquidity/batch: a liquidity score, badge, and expected time-to-sell per item, built from order books and completed sales.
/v1/liquidity/:marketHashName /v1/liquidity/batch
NEW
APIGET /v1/liquidity/summary/:marketHashName: a lightweight per-item liquidity read.
/v1/liquidity/summary/:marketHashName
NEW
APIGET /v1/liquidity/items and /v1/liquidity/items/manifest: the whole catalog's liquidity as one ETag-cacheable snapshot.
/v1/liquidity/items /v1/liquidity/items/manifest
IMPROVED
APImin-prices and max-orders accept marketHashNames as an alternative to ids.
/v1/aggregations/min-prices /v1/aggregations/max-orders
SECURITY
APIRate limits are pooled per subscription: every key on an account shares one per-minute and one monthly budget, with up to 5 active keys per subscription. This closes a gap where extra keys multiplied throughput.
Rate Limits Authentication
IMPROVED
APINew API keys use the sp_live_ prefix; older sk_ keys keep working. There is no separate test environment, so every key reads the same live data.
Authentication
FIXED
API/v1/market-analytics returned the sell_* and buy_* fields in dollars next to integer-cent current_ask and current_bid. All price fields are now integer USD cents.
/v1/market-analytics/:marketHashName
FIXED
API/v1/items now splits a comma-separated markets filter. Multi-market filters previously returned no quotes.
/v1/items
FIXED
APIspreadBps on NBBO and pricing is null instead of an extreme value when the spread would exceed 10000 bps (100%), which almost always means a stale bid.
/v1/nbbo /v1/pricing/:marketHashName Reading prices: ask, bid & NBBO
FIXED
Market dataListings not re-fetched within 48 hours are excluded from listings, aggregates, and listing counts, so a quietly stalled market can't quote stale prices.
/v1/pricing/:marketHashName/listings /v1/pricing/:marketHashName
FIXED
APIThe cross-market spread in price history uses a cash-executable, non-crossing bid, matching live NBBO.
/v1/pricing/:marketHashName/history
NEW
Market dataCS.Deals and Avan.Market join the feed.
NEW
DocsEvery endpoint and concept has its own reference page with field, error, and access tables, an API Objects page, and a Markdown twin of every page for LLM tooling.
API Objects

v1.0.0

Jun 14, 2026SkinPricer launch

NEW
APIREST API v1: cross-market NBBO, order-book depth, full pricing snapshots, per-listing samples with float data, price history (aggregate and per market), recommendations, item search, batch min and max prices, and per-market analytics.
/v1/nbbo /v1/nbbo/depth /v1/pricing/:marketHashName /v1/pricing/:marketHashName/listings /v1/pricing/:marketHashName/history /v1/pricing/:marketHashName/history/markets /v1/recommendations/:marketHashName /v1/items /v1/aggregations/min-prices /v1/aggregations/max-orders /v1/market-analytics/:marketHashName
NEW
APIGET /v1/arbitrage/opportunities: ranked cross-market arbitrage pairing a fresh ask on one market with a fresh bid on another, with spread, estimated net, tradable quantity, and per-leg freshness.
/v1/arbitrage/opportunities
NEW
APIPer-attribute prices: GET /v1/attribute-prices/latest and /history for float, fade, and pattern buckets across markets, plus the BUFF-scoped /v1/markets/buff163/latest and /history.
/v1/attribute-prices/latest /v1/attribute-prices/history /v1/markets/buff163/latest /v1/markets/buff163/history How attribute & float buckets are built
NEW
APIExecution-adjusted NBBO: an executionAdjusted block that re-ranks venues by what you would actually pay and receive after fees, with its own spread and confidence.
/v1/nbbo Reading prices: ask, bid & NBBO
NEW
APIIn the default all-markets view, the NBBO best bid only considers cash-executable venues, so Steam wallet credit can't produce a false crossed book. Pass an explicit markets list to include every venue.
/v1/nbbo Reading prices: ask, bid & NBBO
NEW
APIPrice history picks its bucket size from the requested range, or takes an interval param (MINUTE_5, MINUTE_15, HOUR_1, HOUR_6, DAY_1) that snaps to the nearest stored rollup: 10m, 1h, or 1d.
/v1/pricing/:marketHashName/history
NEW
APIOperational reads: per-market ingest freshness (/v1/status/freshness) and ingest latency (/v1/status/market-latency), plus Market Health (/v1/markets/health), the one keyless endpoint, with 48 half-hour health bars per market.
/v1/status/freshness /v1/status/market-latency /v1/markets/health
NEW
APIAPI keys with per-plan minute and monthly quotas. Authenticate with Authorization: ApiKey <key> (Bearer also works); every key-gated response carries X-RateLimit-* headers, and a 429 comes with Retry-After.
Authentication Rate Limits
