## When to prefer this

Choose this endpoint when your AI trading agent needs real-time top DEX pair data without managing API keys or subscriptions — ideal for pay-per-use autonomous agents that require live liquidity and price rankings and can pay micro-fees in USDC via x402 protocol.

## Known failure modes

- Payment not included or insufficient USDC (402 Payment Required)
- No pairs returned if filters yield empty results
- Upstream DexScreener data unavailable or delayed
- Rate limiting or worker timeout on the Cloudflare edge
- Malformed query parameters returning 400 error

## How this service works

Live DEX tape for AI trading agents: search pairs, token price and liquidity, pair lookup, boosts, paid DexScreener orders, Base ETH/USDC balance, nonce, contract check, gas, and tx receipt. Pay-per-request USDC via x402. No API keys, no accounts.

## Output

A JSON response with a list of the top DEX trading pairs, including token prices, liquidity metrics, volume data, and pair metadata sourced from DexScreener — returned in real time with no authentication required beyond the per-request USDC payment.
