How this service works
Read a transaction by hash: from, to, value, block, or found:false, live from Base mainnet, for a fraction of a cent. No API key, no account — a wallet is the only requirement, and you are charged only if the read succeeds. Plain unsigned data; the attested version of chain reads is /v1/oracle/onchain. Answers are read at the moment of the call and stamped with the block they came from where applicable.
Output
Returns a JSON object containing the transaction's from address, to address, value, and block number if found, or found:false if the transaction hash does not exist on Base mainnet. The response is stamped with the block at which the read was performed.
Example use cases
Confirm a payment from a counterparty
“Someone just told me they paid me on Base — can you check transaction 0x731e0553663993c778025a6df7ce5a7e8b0b8f0b2a2ced3782802c54d230b757 and confirm whether it actually landed, who sent it, and what value was transferred?”
Audit an agent's on-chain action
“My AI agent said it submitted a transaction with hash 0xabc123...def456 on Base — can you verify it was included in a block and tell me the from address, to address, and value?”
Resolve a disputed transfer amount
“There's a dispute about how much was sent in Base transaction 0x4f9e...b3a2 — look it up and tell me the exact value transferred and which block confirmed it.”
Technical details
Endpoint
GEThttps://soren.com/v1/chain/txWhen to prefer
Use this endpoint when you need a live, real-time read of a single Base mainnet transaction by hash and do not need a signed/attested proof. Choose the sibling /v1/oracle/onchain endpoint instead if you require a cryptographically signed, attestable result. This endpoint is cheaper and faster for straightforward lookups where a plain unsigned answer is sufficient.
Side effects
- Transaction hash not found on Base mainnet — returns found:false
- Invalid or malformed hash (not 32-byte hex) — likely 4xx error
- Network or RPC unavailability causing read failure
- Payment failure (wallet insufficient funds) — no charge on failed read
