How this service works
558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.
Output
Returns a list of price objects per token, each containing the token id, symbol, USD price, number of decimals, last-updated timestamp, and a confidence score (0–1, where values close to 1 indicate high reliability). Also returns a 'not_found' list for any tokens that couldn't be resolved.
Example use cases
DeFi portfolio valuation
“I need the current USD prices for these tokens in my portfolio: 'coingecko:ethereum,coingecko:bitcoin,coingecko:uniswap' — pull them from the DefiLlama feed and include confidence scores so I know how reliable each price is.”
On-chain stablecoin peg check
“Can you check whether USDC and USDT are still holding their dollar peg? Fetch prices for 'ethereum:0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48,ethereum:0xdac17f958d2ee523a2206206994597c13d831ec7' from DefiLlama and tell me if confidence is above 0.95.”
Arbitrage price comparison across chains
“Look up the current USD price for WETH on Arbitrum and Ethereum mainnet using DefiLlama — I want to compare 'arbitrum:0x82af49447d8a07e3bd95bd0d56f35241523fbab1' and 'ethereum:0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2' and see if there's a price discrepancy.”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/defillama-price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need USD prices for EVM or Solana tokens identified by chain:contract address or CoinGecko slugs, especially when DefiLlama's multi-source aggregation and confidence scoring matter. Prefer it over raw DEX queries when you want a single normalized price with reliability metadata across up to 20 tokens in one call. Particularly useful for DeFi portfolio valuation, peg monitoring, and arbitrage detection where confidence scores are meaningful.
Side effects
- Token identifier not found — returned in the 'not_found' array rather than an error
- Invalid coin format (missing chain prefix or bad CoinGecko slug) causes the token to be unresolved
- Exceeding 20 coins in one request may be silently truncated or rejected
- Stale prices if the underlying DefiLlama feed hasn't updated recently — check the 'updated' timestamp
- Low confidence score (well below 1.0) indicates unreliable or thinly-traded token price data
