Output
Returns a JSON object with keys: summary (overview of transfer activity), top_senders (ranked addresses sending the token), top_receivers (ranked addresses receiving the token), large_transfers (notable high-value transfer events), risk_flags (detected anomalies or risk signals), and sources (data provenance). All scoped to the specified ERC20 token and block window on Base.
Example use cases
Example prompt
“Pull the token flow risk analysis for the Base USDC contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 over the last 2000 blocks and show me the top 10 senders, receivers, any large transfers, and flag any risk signals you see.”
Technical details
Endpoint
GEThttps://xx402.icu/x402/api/base-token-flow-riskWhen to prefer
Use this endpoint when you need onchain token flow intelligence specifically on the Base network — particularly top sender/receiver rankings, large transfer detection, and automated risk flagging for a given ERC20 token. Prefer this over generic block explorers when you need structured, risk-scored output ready for agent consumption at $0.01 per call.
Side effects
- Invalid token_address format (not a valid 0x ERC20 address) returns a validation error
- window_blocks outside allowed range (100–5000) returns a parameter error
- Token contract with no Transfer events in the window returns empty results
- Unpaid or failed x402 payment returns 402 Payment Required
- Nonexistent contract address returns empty or error response
