How this service works
50 pay-per-call tools for agents over x402 (USDC on Base, Polygon, Solana): crypto market data, token audits, indicators, swap routing, web extraction, DNS/WHOIS/email checks, FX, weather and AI text/image tools.
Output
Returns a JSON object with the transaction status (e.g. 'confirmed', 'pending', 'failed'), the block number it was included in, and the number of confirmations accumulated so far.
Example use cases
Verify DeFi swap settlement
“I just submitted a swap on Uniswap on Ethereum — the tx hash is 0xabc123... — can you check whether it's confirmed and how many confirmations it has so far?”
Confirm cross-chain bridge transfer
“I sent a bridge transfer on Polygon with tx hash 0xdef456... about 10 minutes ago — is it confirmed on-chain yet?”
Track Solana payment receipt
“My customer says they paid me on Solana — the signature is 5xYz789... — can you verify whether that transaction actually went through and is confirmed?”
Technical details
Endpoint
GEThttps://skinwinking.com/api/v1/data/tx-status?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to programmatically verify whether a specific on-chain transaction has settled, how many confirmations it has, or which block it landed in — across Solana, Ethereum, Base, Polygon, or Arbitrum — without requiring a full blockchain node or RPC provider integration. Ideal for post-payment verification, bridge monitoring, or DeFi trade settlement checks.
Side effects
- Invalid or malformed tx hash returns an error response
- Unsupported chain value returns validation error
- Transaction not yet indexed returns pending or not-found status
- Network congestion may cause stale or delayed confirmation counts
- Solana signature format differs from EVM 0x hash — mixing them causes lookup failure
