Introducing Accurate Price Points for BTC, ETH, SOL, XRP & DOGE

When real money rides on a price, "roughly right" isn't good enough. On a Polymarket 5-minute trade the whole outcome can hinge on a single tick - where the candle opened, where it closed, and whether it crossed the line in between. Miss the starting price by a few dollars and your read on the market is already wrong. We built this so you never have to guess.

That's the promise: the correct price, for the exact moment that matters.

What we offer today

A clean REST API that serves accurate, point-in-time Polymarket crypto prices for the five tickers that show up again and again on short-duration markets:

  • Bitcoin (BTC)
  • Ethereum (ETH)
  • Solana (SOL)
  • XRP
  • Dogecoin (DOGE)

Prices are sourced from the same on-chain Chainlink feeds these markets actually reference, streamed live into our database by a listener that never stops watching, and made available two ways: the latest price, or the price at any exact timestamp you name. So whether you want "BTC right now" or "ETH at 17:05:00 UTC, the second that 5-minute window closed," it's one question with one answer.

Why it matters

  • Don't miss the starting price. Pin the exact open of a 5-minute market and know the line you're actually trading against - not the number you happened to glance at three seconds late.
  • Know exactly what it closed at. Ask for the price at the resolution timestamp and get a single, defensible close. No "whose chart?", no disputed candle.
  • No gaps in the record. An auto-reconnecting listener ingests prices continuously, so the history is there every time you look back to settle, audit, or backtest.
  • One source of truth. Stop reconciling three exchange APIs that disagree by a few dollars at the worst possible moment - right when a market is resolving.

For developers

Every request is authenticated with an API key you create and manage yourself - no anonymous access, keys hashed at rest, and an origin/IP allowlist if you want to lock them down further.

# Latest prices
curl -H "X-API-Key: <your-key>" https://your-host/api/crypto_price/

# Price at a specific instant - the open or close of a 5-minute window (RFC3339)
curl -H "X-API-Key: <your-key>" \
  "https://your-host/api/crypto_price/get_price_at/?at=2026-06-26T17:00:00Z"

That's the whole integration. List prices, or pin a timestamp - done.

Get started

  1. Sign up and log in.
  2. Open /account/ and create an API key (copy it - it's shown once).
  3. Send it in the X-API-Key header and start pulling Polymarket crypto prices.
