How this service works

Pay-per-call HTTP APIs, paid with x402 in USDC on Base (eip155:8453): agentkit, api-change-check, basedue, basewatch, chainread, check-sanctions, chgwatch, company-facts, composite, edgar, feednews, pageaudit, solcheck, token-dd, txpreflight, walletcheck, webmd, webread, websearch, x402index. Each operation describes its service.

Output

A JSON object per address containing: a numeric risk score (0–100), a verdict string (e.g. CAUTION, HIGH, SAFE), an array of flag objects each with a code and severity, the chain evaluated, the queried address, and request metadata including payer address and price paid in USD.

Example use cases

DeFi Protocol Counterparty Screening

“Before we send funds to these 10 addresses in our airdrop list on Base, can you run them all through a risk check and flag any that score above 50 or come back with high-severity flags?”

Exchange Withdrawal Compliance Check

“I have a list of 20 Ethereum addresses requesting withdrawals — can you batch-score them for risk and tell me which ones have any flags so I can hold those for manual review?”

Smart Contract Interaction Safety Check

“I'm about to interact with 8 Base addresses pulled from this DeFi protocol — can you score them all for risk and tell me if any come back as high risk or have owner_holds_power flags?”

Technical details

Endpoint

POSThttps://api.firstmention.uk/s/chainread/batch?utm_source=zero.xyz

When to prefer

Use this endpoint when you need to risk-score multiple blockchain addresses in a single API call on Base or Ethereum, avoiding the latency and cost of sequential single-address lookups. It is ideal for compliance pipelines, airdrop screening, withdrawal queues, or any workflow where a list of addresses needs simultaneous evaluation. Prefer this over single-address endpoints when you have 2–25 addresses to check at once.

Side effects

Batch exceeds 25 addresses — request rejected
Invalid or malformed 0x address in the addresses array — may return error or skip that entry
Unsupported chain value (not 'base' or 'ethereum') — schema validation error
Payment failure via x402 — 402 response, no data returned
Address with no on-chain history may return a low-confidence or default score
Network timeout on slow RPC nodes for a given chain
