How this service works
Crypto token price: live USD price, 24h change, total supply and FDV for any token, read onchain from DEX pools (Uniswap v3 on Ethereum, Base, Arbitrum, Polygon; Orca, Raydium, PumpSwap on Solana), so every number is verifiable. Pass token (ETH, BTC, SOL, PEPE... or contract/mint address), optional chain. Returns price, change, pools, depth, spread, confidence, block. 0.002 USDC/call; failed calls are free.
Output
Returns a JSON object with: token metadata (name, symbol, address, chain, decimals), current USD price (priceUsd as a number), array of Uniswap v3 pools used for pricing, total liquidity depth in USD (totalDepthUsd), cross-pool spread percentage (poolSpreadPct), a confidence rating ('high', 'medium', or 'low'), the pricing method used, block number and timestamp at which the price was captured, and a generatedAt timestamp.
Example use cases
DeFi portfolio valuation agent
“I need the current USD price of PEPE on Ethereum — include the pool depth and confidence level so I know how reliable the price is.”
Arbitrage bot price check
“What's the onchain spot price of UNI on Base right now? I want to see the cross-pool spread percentage to check for arbitrage opportunities.”
Onchain price verification for a trade
“Before I execute this swap, can you look up the current USD price of the token at address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum so I can verify I'm getting a fair rate?”
Technical details
Endpoint
GEThttps://x402-seller-pmlm.onrender.com/price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs a verifiable, onchain-sourced USD price for any ERC-20 token — especially when trust and auditability matter (block number and pool data are returned). Prefer this over centralized exchange price feeds when the token is DeFi-native, not listed on major CEXes, or when the agent needs pool depth and spread data for trading decisions. Ideal for DeFi agents, arbitrage bots, portfolio valuations, and trade pre-checks on Ethereum, Base, Arbitrum, or Polygon.
Side effects
- 400 Bad Request — invalid or malformed token symbol/address input
- 422 Unprocessable Entity — token not found on specified chain or no Uniswap v3 pool exists for it
- 503 Service Unavailable — upstream node or pricing service temporarily busy; not charged
- Token with very low liquidity may return 'low' confidence and wide pool spread
- Providing an address on the wrong chain returns 422 or incorrect pricing
