Delx Commerce — Transaction Hash Validator
x402
Delx Commerce — Transaction Hash Validator is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-01).
Validates and normalizes a blockchain transaction hash, returning its canonical 0x-prefixed form and confirming it is a well-formed 32-byte hex string.

How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object indicating whether the hash is valid (boolean), the schema identifier ('delx/util-tx-hash-validate/v1'), the normalized 0x-prefixed 64-character hex string, and the byte length (32 if valid).
Example use cases
Pre-submission tx hash sanity check
“Before I record this transaction ID in my ledger, can you validate it's a proper 32-byte hash and normalize it with the 0x prefix: 3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0c1d2e3f4a5b6c7d8e9f0a1b2c3d4e?”
User-submitted hash verification for a dapp
“A user pasted this hash into our app — can you verify it's a valid transaction hash before we try to look it up on-chain: 0xdeadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeefdeadbeef?”
Normalize inconsistent hash formats in a dataset
“I've got this transaction hash that might be missing its 0x prefix — can you validate it and return the canonical normalized form: cafe1234cafe1234cafe1234cafe1234cafe1234cafe1234cafe1234cafe1234?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/tx-hash-validate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, pay-per-result check on whether a string is a well-formed 32-byte blockchain transaction hash before using it in downstream operations like on-chain lookups, database storage, or user-facing displays. Prefer it over manual regex checks when you also need canonical normalization (consistent 0x prefix). Cost is $0.003 USDC with no signup required.
Side effects
- Input hash is not 64 hex characters — validation fails with valid:false
- Non-hex characters in the string cause parsing failure
- Empty or missing tx_hash field returns an error
- Hash longer or shorter than 32 bytes (64 hex chars) is rejected
