How this service works

84 pay-per-call AI services on x402 V2 — market intel, DeFi execution, AI creative tools. USDC on Base on every endpoint, Solana USDC on 66 of 84. From $0.001 per call.

Output

A JSON object containing a list of all token holdings for the queried Base wallet, each with token name, symbol, native token flag, contract address, formatted balance, USD price, USD value, 24h price change percentage, portfolio percentage, and contract verification status. Also includes total USD value, token count, whether results were truncated, a timestamp, and a 'bagcheckRead' field containing an AI-generated plain-English narrative summarizing the wallet's composition and risk profile.

Example use cases

Example prompt

“Can you pull up the full token holdings and portfolio breakdown for Base wallet 0xc65a451047094cdd723fff77334d3b9ff8cf28e7 — I want to see each token's USD value, price change, and what percentage of the portfolio it makes up?”

Technical details

Endpoint

GEThttps://x402.ottoai.services/wallet-holdings?utm_source=zero.xyz

When to prefer

Use this endpoint when you need a comprehensive, USD-valued snapshot of all token holdings for a specific Base network wallet — especially when you also want an AI-generated narrative summary (bagcheckRead) of the portfolio's composition and risk profile. Prefer this over generic blockchain explorers when you need structured, agent-ready JSON with per-token analytics including price change and portfolio weight.

Side effects

Invalid or malformed wallet address returns an error
Wallet address on a non-Base network may return empty or incorrect data
Very new wallets with no holdings may return an empty holdings array
Rate limiting or payment failure via x402 returns 402 Payment Required
Stale data if cache TTL has expired (check meta.stalenessSec)
Degraded mode indicated by meta.degraded=true may return partial data
