Delx Tx Hash Validate
x402
Delx Tx Hash Validate is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).
Validates and normalizes the format of a 32-byte (64 hex character) transaction hash string, returning a deterministic machine-readable result

How this service works
Validate a 32-byte transaction hash format and normalize casing — call when validating a 32-byte transaction hash format. Use for chain input hygiene without live RPC—adjacent to OneSource-class small chain reads, but static/local only so rights and margin stay clear. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search,…
Output
A deterministic JSON object indicating whether the supplied transaction hash is valid (correct 64-hex-char length, valid hex encoding), the normalized lowercase version of the hash, and any format error details if invalid
Example use cases
Pre-submission tx hash hygiene
“Before I submit this transaction hash to the blockchain explorer, can you validate that it's properly formatted — the hash is 4e3a12f8b9c2d1a7e5f6b3c8d2a9e1f4b7c3d8a2e5f9b1c4d7a3e6f2b8c1d4a7?”
Normalizing user-provided hash input
“A user pasted this transaction hash into my app and I want to make sure it's valid and normalized before processing: 0X4E3A12F8B9C2D1A7E5F6B3C8D2A9E1F4B7C3D8A2E5F9B1C4D7A3E6F2B8C1D4A7”
Agent pipeline input validation
“In my automated workflow, I need to validate this tx hash before passing it to a chain read — can you check if 0x4e3a12f8b9c2d1a7e5f6b3c8d2a9e1f4b7c3d8a2e5f9b1c4d7a3e6f2b8c1d4a7 is a properly formatted 32-byte transaction hash?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/tx-hash-validateWhen to prefer
Use this endpoint when you need fast, local, stateless validation of a transaction hash format without making any live RPC or chain calls — ideal for input hygiene in pipelines before expensive on-chain lookups, or when you want to normalize 0x-prefix casing cheaply and deterministically at $0.003 per call with no external data dependencies
Side effects
- Input hash is too short or too long (not 64 hex characters after stripping 0x)
- Input contains non-hex characters
- Empty or missing tx_hash field
- Malformed JSON request body
- Payment authorization failure via x402 protocol
