ECDSA-Signed Feeds

Every price feed is cryptographically signed with secp256k1 -- verifiable on-chain and in audit trails

Published Methodology

Versioned, transparent pricing methodology -- read exactly how we calculate FMV

13 Asset Verticals

Pokemon, sports cards, watches, wine, LEGO, sneakers, and more -- the broadest alternative asset coverage available

Built by John Lee

Duke CS graduate. Former enterprise developer. Building the pricing layer the alternative asset market needs.

The Problem

$6 trillion in assets. Zero pricing infrastructure.

Funds can't calculate NAV. Lenders can't value collateral. Insurers can't underwrite. The alternative asset market has grown 10x -- but pricing is still stuck in spreadsheets and single-source scrapes.

Single-Source Fragility

One marketplace goes down, one API changes, and your entire pricing engine breaks. Billions in collateral valued from a single feed.

Invisible Sales Data

40%+ of transactions happen off-marketplace -- auction houses, shows, private sales. Existing tools miss them entirely, leaving massive blind spots in valuation.

No Confidence Signal

Is this price based on 50 recent sales or one stale listing? Without cross-source verification, every number is a liability waiting to happen.

No Historical Depth

No time-series, no trend data, no benchmarks. Investors can't model returns, lenders can't assess volatility, and auditors can't verify past valuations.

How It Works

Aggregate. Score. Deliver. Repeat.

A continuous flywheel that gets smarter with every sale. More sources, higher confidence, better prices -- compounding data moats that are impossible to replicate overnight. Read the methodology →

1

Aggregate Every Sale

Proprietary scrapers ingest verified completed sales from 6+ sources -- eBay, auction houses, dealer networks, and private marketplaces. Raw data normalized across grading standards, conditions, and currencies.

2

Score Confidence

Multi-factor weighting model scores each price by source reliability, recency, sale volume, and cross-marketplace agreement. Outliers are flagged, not averaged in. Result: a 0-100 confidence score you can underwrite against.

3

Deliver via API

One REST call returns FMV, confidence, source breakdown, and full time-series history. Sub-200ms latency. ECDSA-signed index feeds for on-chain oracles. Integrate in minutes, audit forever.

Live Demo

See it live. Pick any asset.

Real pricing from real sales across collectibles, luxury watches, and LEGO sets. Not estimates -- actual market data, updated daily.
