How this service works
Pay-per-call crypto market and Base wallet summaries via x402 (USDC on Base).
Output
A JSON object containing the queried wallet address, an array of token holdings (each with symbol, balance, and USD value), the account type (externally_owned or contract), the number of outgoing transactions, and a total USD portfolio estimate.
Example use cases
Portfolio snapshot before DeFi action
“Before I move funds, can you show me the full token holdings and USD estimate for my Base wallet 0xAbC1234567890dEfAbC1234567890dEfAbC12345?”
Due diligence on a counterparty address
“I'm about to send funds to 0x9f3b4d5e6c7a8b9c0d1e2f3a4b5c6d7e8f901234 — can you check what they hold on Base and whether it's an externally owned account or a contract?”
Automated wallet monitoring for an agent
“Every hour, check wallet 0x1a2b3c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9012 on Base and tell me if the total USD value changes by more than 10%.”
Technical details
Endpoint
GEThttps://ralph-crypto-summary.simgokr.workers.dev/api/wallet-profile?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-call on-chain wallet profile for a Base network EVM address — particularly when you want token holdings with USD valuations and account-type classification without setting up your own blockchain node or indexer. Ideal for agents that need occasional wallet lookups rather than bulk or streaming data, and where the low $0.05/call x402 micropayment model is preferred over subscription APIs.
Side effects
- Invalid or malformed EVM address returns an error (non-0x or wrong length)
- Address not found on Base or zero activity returns empty holdings array
- Payment not completed via x402 results in 402 Payment Required response
- Rate limiting or Cloudflare Worker timeout may return 5xx errors
- Base RPC/data source downtime may cause stale or missing data
