How this service works
USD price of up to 20 tokens at any past date and time (BTC, ETH, SOL... or chain:contract ids), with the exact timestamp of the data point. For accounting, taxes and backtests. Aggregated by DefiLlama.
Output
A JSON object containing: the source ('DefiLlama (precio agregado)'), an array of matched tokens each with their ID, symbol, USD price, confidence score (0–1), and exact data point timestamp; the requested date; and a list of any tokens not found.
Example use cases
Year-end crypto tax reporting
“Pull the USD price of BTC, ETH, and USDC on December 31 2024 at midnight UTC — I need the exact values with timestamps for my annual tax return.”
DeFi backtest price data
“For my trading backtest, get the historical USD prices of coingecko:uniswap, coingecko:aave, and coingecko:chainlink on March 15 2024.”
On-chain token accounting by contract
“What was the USD price of the USDC contract at base:0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 and ETH on January 1 2025? I need this for reconciling a DeFi transaction.”
Technical details
Endpoint
POSThttps://api.vextorium.com/precio-historico-pago?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need USD prices of crypto tokens at a specific historical point in time — especially for tax, accounting, or backtesting workflows. It supports up to 20 tokens per call including major assets (BTC, ETH, SOL) and any EVM token by chain:contract or CoinGecko slug, and returns DefiLlama-aggregated prices with confidence scores and exact data timestamps. Prefer this over live-price endpoints when historical accuracy and auditability matter.
Side effects
- Token not recognized by symbol or contract address — returned in 'no_encontrados' array
- Invalid date format causes request failure — must be YYYY-MM-DD, ISO 8601, or Unix timestamp
- More than 20 tokens requested — may result in partial or error response
- Date too recent (no historical data point yet) or too far in the past — token may appear in not-found list
- Network or aggregator downtime causing no data returned
