How this service works
Pay-per-call APIs for AI agents over x402: token safety reports, Base and Ethereum on-chain reads, crypto prices, domain checks (DNS, WHOIS, SSL, email), finance data (FX, SEC), worldwide weather forecasts, France alerts, text AI, fun content. USDC on Base, no account, no API key.
Output
A JSON object containing the best quote (venue name, human-readable and raw amount_out, pool fee percentage, low_liquidity boolean) and a ranked list of all quotes from Uniswap v3 fee tiers and Aerodrome stable/volatile pools, plus the token addresses and network identifier.
Example use cases
Pre-trade DEX price check
“Before I swap 500 USDC for ETH on Base, check all the DEX venues — Uniswap v3 and Aerodrome — and tell me which gives the best rate and whether liquidity is low.”
Arbitrage opportunity scan
“Compare the swap rate for 1 cbBTC to USDC on Base across Uniswap v3 (all fee tiers) and Aerodrome right now and show me the ranked quotes so I can spot the best deal.”
Low-liquidity token screening
“I want to swap 10,000 DAI for this token at address 0x940181a94A35A4569E4529A3CDfB74e38FD98631 on Base — get me a live quote and flag if liquidity is dangerously low.”
Technical details
Endpoint
GEThttps://api.zkrobotics.fr/x402/base/swap-quote?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a real-time, multi-venue DEX price comparison on Base before deciding whether or where to execute a swap — especially when you want Uniswap v3 fee-tier granularity alongside Aerodrome stable/volatile pool pricing in a single ranked response, without triggering any on-chain transaction.
Side effects
- Missing or invalid token_in/token_out address returns a 400 error
- amount_in not matching the numeric pattern (e.g. letters) returns a validation error
- No liquidity found for the token pair returns an empty quotes array or low_liquidity: true
- Token address for an unsupported or non-existent contract returns an error or zero quotes
- Payment not included or insufficient triggers a 402 Payment Required response
