How this service works
cairnworks verify — fixed-price x402 (USDC on Base) checks for agent payouts: verify a Base/BSC transaction receipt and ERC-20 transfers (0.01), audit a URL's status/redirects/paywall flags (0.01), token holder and treasury share audit at a block (0.02), batch-verify up to 10 payout receipts (0.02). No account, no API key; every response is signed JSON with a sha256 evidence digest. Free sample outputs at /samples (no payment).
Output
Returns a signed JSON object containing: token metadata (symbol, address, decimals, total supply), per-holder breakdown (address, balance in human-readable form, percentage share, account type EOA/contract, code size), the resolved block hash and number, chain ID, a list of measured vs unmeasured addresses, and a SHA-256 evidence digest for auditability.
Example use cases
Pre-distribution snapshot audit
“Before we do the airdrop, can you audit how much of the FLAPJAX token (0x90c8...) each of these 5 treasury wallets holds on BSC at block 128409663? I need the balance percentages and a signed evidence digest I can share with the team.”
Token concentration check for DeFi listing
“We're reviewing a Base project token at address 0xABCD... — can you pull the holder shares for these 10 wallet addresses at the latest block on Base and tell me if any single wallet controls more than 20% of supply?”
Verify payout recipient holdings on BSC
“After our last payout round, I need to confirm the recipient wallets still hold their claimed token balances — can you audit these 8 addresses against the BSC USDT contract at block 128000000 and give me a verifiable JSON receipt?”
Technical details
Endpoint
POSThttps://cairnworks-verify.run402.com/holder-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cryptographically signed, auditable proof of ERC-20 token holder balances and share percentages at a specific block on Base or BSC — especially for pre-distribution snapshots, treasury audits, or verifying payout recipient holdings. It requires no API key or account, costs a flat $0.02 USDC per call via x402, and returns tamper-evident evidence digests. Prefer it over general blockchain RPC calls when you need structured, human-readable output with built-in auditability.
Side effects
- Invalid token contract address (not ERC-20 or non-existent) returns error
- Block number not yet finalized or out of range
- More than 20 holder addresses submitted (maxItems exceeded)
- Unsupported chain value (only base, bsc, base-sepolia accepted)
- Payment failure via x402 protocol results in 402 response with no data
- Malformed wallet address (non-hex or wrong length) rejected by pattern validation
