How this service works
Obol sells verified blockchain data over x402, settled in USDC on Base.
Output
Returns a JSON object indicating whether the transaction was found on Cardano mainnet, the network identifier ('cardano-mainnet'), coverage metadata including match type ('exact_transaction_hash') and maximum results (1), the queried transaction hash, and a 'transaction' field containing full transaction details if found or null if not found.
Example use cases
Verify ADA payment received
“I need to confirm that a Cardano payment went through — the transaction hash is f3c2b1a0d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0c1d2e3f4a5b6c7d8e9f0a1. Can you check if it's on the Cardano mainnet and show me the transaction details?”
Audit blockchain transaction trail
“I'm auditing some on-chain activity and need to pull verified data for Cardano transaction hash 9b8c7d6e5f4a3b2c1d0e9f8a7b6c5d4e3f2a1b0c9d8e7f6a5b4c3d2e1f0a9b8. Can you fetch the full transaction record from Cardano mainnet?”
Smart contract execution confirmation
“Our dApp just submitted a Cardano smart contract transaction — hash is 1234abcd5678efgh9012ijkl3456mnop7890qrst1234uvwx5678yzab9012cdef. Can you verify it landed on Cardano mainnet and return what Obol found?”
Technical details
Endpoint
GEThttps://obol.danieldutoit.net/v1/cardano/transactionWhen to prefer
Use this endpoint when you need verified, on-chain Cardano transaction data by exact transaction hash on mainnet. Prefer this over generic blockchain explorers when you need a paid, programmatic, API-accessible result settled via x402/USDC — especially in automated agent workflows that require a structured JSON response rather than a web scrape. Not suitable for Ethereum, Bitcoin, or other non-Cardano chains.
Side effects
- Transaction hash not found — returns found: false with transaction: null
- Invalid or malformed transaction hash — may return an error or not-found response
- Network unavailability — service may be temporarily unreachable
- Payment failure — x402 USDC payment on Base not settled, request blocked
- Hash exists on a different Cardano network (testnet vs mainnet) — returns not found
