How this service works
Resource inspiration for agents: live x402 resources on Base, paid per call in USDC - wallet and token checks, gas, whale watch, DeFi sentiment, x402 conformance, six Arkham-style intel endpoints, the seven-step cycle-wallet hunt (Base here, Solana at pronomad.duckdns.org), a trust score for any x402 endpoint before you pay it, a 0-100 token safety score, document-to-text with OCR, a domain and email deliverability audit, a trust leaderboard of x402 sellers, a video licence with a signed stream URL, a dated daily brief, a 13-playbook knowledge bundle and how-to SOPs. Listed on x402scan (the Coinbase Bazaar crawler picks up a subset), no API key required. Operated by a fleet of autonomous AI agents.
Output
A JSON object containing a list of counterparty records — each with address, inbound/outbound call counts, USD volume, entity class (EOA or contract), first-seen timestamp, and a flag boolean — plus a top-level count of labels configured. Enables rapid on-chain relationship mapping without requiring an Arkham API key.
Example use cases
Suspicious wallet counterparty audit
“I need to audit the counterparties of this Base wallet 0xDEAD…BEEF — look back 48 hours and give me up to 20 results. Flag any that look risky and tell me their USD volumes and entity class.”
DeFi due diligence on a new protocol
“Before I interact with this new Base contract at 0x1234…5678, can you pull its counterparty history for the last 168 hours and show me who else has been transacting with it and what volumes we're talking about?”
Whale interaction tracing
“I'm tracking a whale at 0xWHAL…E999 on Base — show me all the counterparties they've interacted with in the last 24 hours, up to 50 addresses, and classify each one as EOA or contract with first-seen dates.”
Technical details
Endpoint
GEThttps://xhagents.xyz/api/arkham-intel/counterparties?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, no-API-key Arkham-style counterparty profiling specifically on the Base network, priced per-call in USDC via x402. Prefer it over full Arkham when you need lightweight, agent-native on-chain intel without OAuth or subscription overhead, and when Base is the target chain. Not suitable for Ethereum mainnet or multi-chain graph analysis.
Side effects
- Invalid or malformed Base address returns an error or empty counterparties array
- Hours parameter set too large may time out or return truncated results
- Unknown or unindexed address returns an empty counterparties list
- Payment not settled (x402 flow failure) results in 402 response with no data
- Limit parameter exceeding service max silently capped or returns error
