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: a 'result' field containing the matched boolean, the actual matched asset name, and the full list of supported assets; a 'status' field ('pass'/'fail'); an 'operation' identifier; and an 'evidence' block with a SHA-256 hash of the input and confirmation that no data was retained and no external calls were made.
Example use cases
Pre-payment asset compatibility check
“I'm about to make an x402 payment using USDC — can you verify it's in the supported asset list [USDC, DAI] before I proceed?”
Agent payment routing validation
“My agent wants to pay with USDC on Base, and the endpoint says it supports [USDC, EURC]. Check if USDC is a valid match before sending the payment.”
Multi-asset fallback selection
“I have ETH and USDC available. The endpoint accepts [USDC, SOL]. Run asset matching to see which of my assets is supported so I know which one to use.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/x402-asset-match?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to deterministically verify that a specific payment asset is accepted before initiating an x402 micropayment, especially when proof of in-memory-only processing and no data retention is required. Prefer this over custom logic when verifiable, auditable asset matching with a cryptographic input hash is needed.
Side effects
- Asset not in supported list — returns matched: false with status indicating no match
- Invalid or empty asset string — may return error or unmatched result
- Supported assets array exceeds 256-item limit — request rejected
- Malformed request body — returns schema validation error
