credits: 1
usdc: '0.01'
description: Look up the identity label of an EVM address (Base, open eth-labels dataset; mostly category tags rather than named entities). Returns which entity the address belongs to; unlabelled addresses return null. Call with no arguments for a free demo result.

readOnly: true
- name: detect_cluster
credits: 5
usdc: '0.05'
description: Detect the set of addresses funded by a single funder (shared funding-source cluster). Useful for sybil / entity detection.
readOnly: true
- name: query_alerts
credits: 1
usdc: '0.01'
description: Query historical alert records; filterable by address, rule kind, severity, and time range.

usdc: '0.03'
description: 'CCTP cross-chain transfer tracking: given a source-chain tx hash, find which transfer it belongs to, how much moved, the destination chain, and whether it arrived. Supports Base → Ethereum and other CCTP chains.'
readOnly: true
- name: list_paid_endpoints
credits: 1
usdc: '0.01'
description: List every paid HTTP endpoint of this service with its live per-call price in USDC on Base. Takes no arguments. Call this first to discover what you can buy and what it costs.

howToCall:
- 'POST https://agentsapi.top/mcp with Content-Type: application/json and Accept: application/json, text/event-stream'
- 'Body is JSON-RPC 2.0: initialize (free) → tools/list (free) → tools/call (paid)'
- A paid tool/call returns a PaymentRequired object inside the JSON-RPC result; the /mcp protocol plane itself never returns HTTP 402
- 'Pay USDC on Base to payTo, then retry tools/call with the payer address as Authorization: Bearer <address> (or x402 payment-signature header)'
- 'Anonymous free tier: 7 tool calls per IP per day, 1 per tool across all 7 tools (get_label, explain_transaction, detect_cluster, query_alerts, alert_stats, track_cctp, list_paid_endpoints; no wallet, no signup)'
