💵 $0.001 USDC per call 🌐 Base 📈 95 calls / 30d · 9 unique payers

Returns trending tokens across the entire blockchain for a specified activity window and optional category. The size of the increase in active wallets over the activity window determines the token's trending rank.

This endpoint speaks x402: an unpaid request returns HTTP 402 with machine-readable payment terms, your agent pays the $0.001 USDC in USDC on-chain, and retries automatically. Pays to 0xd85096fAeC1aC03075667B4C1a1661F5623Bf111.

# 2) Paying + retrying requires an x402 client that can sign the USDC
