prices.minute

​
Overview

The prices.minute table provides minute-level price data for tokens across multiple blockchains using the same hybrid approach as all other price tables:
  1. Coinpaprika prices for tokens where we have reliable external data (~2,000 major tokens)
  2. DEX-derived prices for the long tail of tokens not covered by coinpaprika
Minute-level data uses interpolation from hourly anchor points to provide smooth, continuous pricing.
Minute-level data uses interpolation between hourly anchor points for smooth pricing. Forward-filling is applied for up to 48 hours when no trading activity exists.

​
Implementation Details

The minute prices are built using the hybrid approach with interpolation:
  1. Source prioritization: Coinpaprika prices for ~2,000 major tokens, DEX-derived prices for long tail tokens
  2. Hourly interpolation: Uses hourly data as anchor points for linear interpolation
  3. Linear interpolation: Implements interpolation between hourly anchor points to create smooth minute-level data
  4. Noise reduction: Reduces noise and outliers by using stable hourly data points as anchors
  5. Forward-filling: The system forward-fills with the last available price for a maximum of 48 hours (2880 minutes) to avoid stale data
  6. Continuous time series: Provides minute-by-minute data points for every minute between hourly anchors

​
Source-Specific Variants

​
prices_coinpaprika.minute

For purely coinpaprika-based minute prices:
  • Coverage: Only tokens with Coinpaprika listings (~2,000 tokens)
  • Source: External exchange-aggregated minute pricing with interpolation
  • Use case: When you need minute-level external price validation
  • Key role: Serves as the underlying source for the prices.usd legacy view
  • Schema: Same as prices.minute but source is always ‘coinpaprika’

​
prices_dex.minute

For purely DEX-derived minute prices:
  • Coverage: All tokens with sufficient DEX trading volume
  • Source: On-chain DEX trading activity with interpolation
  • Use case: When you need minute-level pricing that reflects on-chain activity
  • Schema: Same as prices.minute but source is always ‘dex.trades’

​
Usage

This table is ideal for high-frequency analysis and examining short-term price movements. It’s particularly useful for studying price impacts of specific events or transactions with high temporal precision. Important Notes:
  • The minute-level data is interpolated from hourly anchor points using the hybrid approach
  • Provides comprehensive token coverage through coinpaprika and DEX-derived sources
  • Provides smooth and consistent pricing while reducing the impact of noise and outliers

​
Latency and Update Frequency

The prices.minute table is updated hourly based on the upstream data pipeline. As a result, prices typically have a latency of approximately 1 hour from real-time.

​
Usage Examples

Here are some examples of how to use the prices tables.

​
Get minute-by-minute ETH prices during a specific event:

SELECT
  timestamp,
  price
FROM prices.minute
WHERE
  blockchain = 'ethereum'
  AND contract_address = 0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2 -- WETH
  AND timestamp >= NOW() - INTERVAL '2' HOUR
  AND timestamp <= NOW() - INTERVAL '1' HOUR
ORDER BY timestamp

​
Analyze price volatility within short time frames:

SELECT
  date_trunc('hour', timestamp) as hour,
  max(price) - min(price) as price_range,
  (max(price) - min(price)) / min(price) * 100 as volatility_pct
FROM prices.minute
WHERE
  blockchain = 'ethereum'
  AND contract_address = 0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2 -- WETH
  AND timestamp >= NOW() - INTERVAL '1' DAY
GROUP BY 1
ORDER BY 1

Data Quality Notes

  • Due to its high granularity, queries on this table may be more resource-intensive
  • Consider using prices.hour or prices.day for longer time ranges if minute-level precision is not required
  • Comprehensive coverage: Includes both coinpaprika and DEX-derived tokens through hybrid approach
  • Native tokens (like ETH, BNB) are assigned fixed addresses for consistency
  • Always use contract_address and blockchain for precise token identification, never use symbol for joins or filters
  • Interpolated Pricing: Minute-level data is interpolated from hourly anchor points using hybrid methodology
  • Reduced Noise: The interpolation approach reduces the impact of noise and outliers
  • 48-Hour Forward-Fill: The system forward-fills with the last available price for a maximum of 48 hours (2880 minutes) to avoid stale data
  • External source reliability: Coinpaprika data provides stable, exchange-aggregated pricing
  • DEX-derived limitations: DEX-derived prices can contain errors due to low liquidity, market manipulation, or anomalous trades
  • Fallback option: For critical applications, consider using prices_coinpaprika.minute for more reliable pricing where available
  • Data validation: Always validate prices for critical applications, especially for lesser-known tokens
