How this service works
Merkle root over a list of leaves — Genesis402 / UnyKorn Operator Network
Output
Returns a JSON object with ok=true, a type field set to 'merkle-root', the computed Merkle root hash, a generated_at ISO8601 timestamp, and a payment receipt containing a transaction hash, USD amount charged, and a unique receipt ID.
Example use cases
Smart contract data verification
“I have a list of 8 transaction hashes I need to commit to an Ethereum smart contract — can you compute the Merkle root over them so I can use it as the commitment value?”
Airdrop eligibility proof generation
“I'm building a token airdrop and have a list of 500 wallet addresses as leaves — compute the Merkle root so I can store it on-chain and later generate inclusion proofs.”
File integrity batch verification
“I've got a set of file content hashes and I want to collapse them into a single Merkle root I can publish as a tamper-evident checksum — can you run the merkle root calculation over this leaf list?”
Technical details
Endpoint
POSThttps://twin.unykorn.org/merkle-root?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pay-per-call, trustless Merkle root computation without running your own hashing infrastructure — especially useful in blockchain or smart contract contexts where on-demand cryptographic computation with a verifiable receipt is needed. Prefer it over rolling your own when you need an auditable receipt tied to each computation or when integrating into an x402-compatible agentic workflow.
Side effects
- Empty or null leaves array returns an error
- Invalid or malformed leaf data causes computation failure
- Unsupported hash algorithm identifier returns an error
- Payment failure via x402 protocol blocks request processing
- Malformed JSON input returns a 400-class error
