How this service works
Crypto price in USD and EUR from on-chain sources only: Chainlink oracles (BTC, ETH, USDC) or Uniswap v3 quotes on Base (USDT, DAI or any Base token address); EUR via ECB rate.
Output
Returns a JSON object containing the token's price in USD and EUR (as numbers), the data source used (e.g. Chainlink, Uniswap v3), the token name, the UTC timestamp of the last update, and an optional advisory notice string (e.g. if liquidity is low or the source has caveats).
Example use cases
DeFi app real-time price feed
“I need the current on-chain price of USDC in both USD and EUR — pull it from Chainlink, not any centralized exchange.”
Portfolio valuation in euros
“What's Bitcoin worth right now in EUR? I want the price from on-chain sources only, not CoinGecko or Binance.”
Custom Base token price check
“Can you look up the current price of the Base token at address 0x4200000000000000000000000000000000000006 in USD and EUR using Uniswap v3?”
Technical details
Endpoint
POSThttps://api.vextorium.com/precio-cripto-pago?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a trustless, decentralized price source for BTC, ETH, USDC, USDT, DAI, or any arbitrary ERC-20 token on Base — especially when you cannot rely on centralized exchange APIs (e.g. CoinGecko, Binance). Ideal for DeFi apps, on-chain settlement calculations, or compliance workflows requiring auditable price provenance. Prefer it over CEX APIs when regulatory or trust requirements demand on-chain sourcing.
Side effects
- Token symbol not recognized and not a valid Base contract address — returns null prices
- Token address exists but has no Uniswap v3 pool on Base — lookup fails or returns null
- Low liquidity on Uniswap v3 pool causing unreliable price quote — advisory notice included in response
- ECB rate unavailable causing EUR price to be null
- Chainlink feed temporarily stale — price returned with staleness warning
