Delx Commerce ABI Type Indexer
x402
Delx Commerce ABI Type Indexer 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).
Accepts an array of Solidity ABI type strings and returns a frequency index showing how many times each type appears

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 with an 'index' array where each entry lists a type string and its occurrence count, plus 'type_count' (total entries), 'unique_types' (count of distinct types), and a schema identifier. Explicitly notes this is an index only and does not perform encoding or eth_call.
Example use cases
Auditing ABI type distribution
“I have this list of ABI types from a smart contract: address, uint256, bool, address, bytes32, uint256, address — can you count how many times each type appears and give me a breakdown?”
Comparing parameter type frequency across functions
“I want to understand the type composition of my ABI. Here are the types from all the function parameters: uint256, address, bytes, uint256, bool, address — index them and tell me which types are most common.”
Validating type diversity before encoding
“Before I encode these ABI parameters, can you index these types and tell me the unique type count and how many total there are: address, uint256, bytes, address?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/abi-type-index?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick frequency index of Solidity ABI type strings — for example, to audit type diversity, understand parameter composition, or preprocess types before encoding. It does not encode values or make on-chain calls, so choose it purely for counting and summarization tasks.
Side effects
- Empty or missing 'types' array returns an empty index
- Invalid or non-standard ABI type strings may be indexed as-is without validation errors
- Payment failure via x402 returns HTTP 402 and no result
- Malformed JSON body returns a 4xx error
