x402
Delx Commerce — Agent Result Envelope Check is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).
Validates that an agent's result object conforms to a standard delivery envelope schema, confirming presence of required fields and data integrity without retaining input.

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 'valid' boolean, a 'missing_fields' array listing any absent required fields, a 'has_data_or_error' boolean confirming payload content, an overall 'status' (pass/fail), and an evidence block containing the input SHA-256 hash, a 'retained: false' flag confirming no data is stored, and an external_calls count of 0.
Example use cases
Pre-delivery agent result audit
“Before I submit this agent result to the client, run it through the Delx envelope check to make sure all required fields are present and it has either data or an error populated.”
Automated pipeline quality gate
“At each step of my agent pipeline, validate the result envelope so the workflow only continues if the result passes — tell me which fields are missing if it fails.”
Debugging malformed agent output
“My agent keeps getting rejected downstream — can you run this result object through the envelope check and show me exactly which fields are missing or invalid?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/agent-result-envelope-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, privacy-preserving, verifiable check that an agent result object conforms to the standard delivery envelope schema before submission or downstream processing. Prefer it over manual schema checks when you need a cryptographic evidence record (SHA-256) proving the check was performed without data retention, or when operating within a pay-per-result agent commerce workflow on Base or Solana via x402.
Side effects
- Input object exceeds 128 properties (maxProperties limit) — request rejected
- Malformed JSON body — parsing error returned
- Result object missing entirely — validation cannot proceed
- Payment not included or insufficient USDC — 402 response before processing
