How this service works
Pay-per-call on-chain API for AI agents and developers: wallet audits, token safety audits (honeypot detection), live gas prices, token prices, transaction receipts, balances, ENS resolution, block data, ERC-20 allowances, transaction simulation, swap quotes and multicall batches — all computed on-chain via public RPCs (no external market API). Pay per request in USDC on Base via the x402 exact scheme (EIP-3009 transferWithAuthorization). No API key, no signup, no subscription.
Output
A list of results per requested token, each containing: spot USD price (derived from the most liquid DEX pool on Base), circulating supply, and market cap. The response also indicates which DEX pool (Uniswap V3 or Aerodrome V2) was used to compute the price.
Example use cases
Portfolio valuation for Base tokens
“I hold WETH, CBETH, and USDC in my Base wallet — can you get me the latest USD spot prices and market caps for all three so I can see what my portfolio is worth right now?”
DeFi dashboard market data refresh
“Refresh market data for these 10 Base tokens for my dashboard: WETH, USDC, DAI, AERO, BRETT, DEGEN, TOSHI, BALD, HIGHER, and MOG — I need spot price, supply, and market cap for each.”
Arbitrage opportunity pre-check
“Before I make a trade, can you fetch the on-chain USD prices for WETH and AERO on Base from Uniswap V3 and Aerodrome V2 so I can compare them?”
Technical details
Endpoint
GEThttps://x402-audit.tatschluizguilherme.workers.dev/priceWhen to prefer
Choose this endpoint when you need on-chain, DEX-derived USD prices for Base tokens — especially when you want prices that reflect actual liquidity rather than off-chain oracle feeds. It's ideal for batch pricing of up to 30 tokens in a single call and when you need supply and market cap alongside the spot price. Prefer it over general crypto price APIs when accuracy to on-chain DEX state (Uniswap V3 / Aerodrome V2) is important.
Side effects
- Token has no liquid DEX pool on Base — price cannot be computed
- Token address is invalid or not an ERC-20 on Base
- More than 30 tokens requested — batch limit exceeded
- On-chain RPC call fails or times out
- Payment of 0.1 USDC not provided — x402 payment required error
