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 top-level 'result' containing a boolean 'valid' flag, a 'checks' map showing pass/fail for each sub-check (post, x402_path, positive_price, required_present), and a 'missing_fields' array. Also includes 'status' (pass/fail), 'schema' identifier, and an 'evidence' block with the SHA-256 hash of the input, a 'retained: false' flag confirming no data is stored, and an external_calls count.
Example use cases
Pre-publish x402 route validation
“Before I add this route to the x402 catalog, can you verify it's well-formed — check that it has a POST method, a valid x402 path, a positive price, and no missing required fields?”
Debugging a rejected catalog route
“My x402 route keeps getting rejected from the catalog — can you run a check on it and tell me exactly which fields are missing or invalid?”
CI check for x402 route compliance
“As part of my deployment pipeline, can you validate this route object against the x402 catalog spec and fail the build if any checks don't pass?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/x402-catalog-route-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify that a route object conforms to the x402 catalog specification before publishing or registering it. It is the canonical validation utility for x402 catalog routes on Delx Commerce, providing granular per-check breakdowns and a tamper-evident SHA-256 hash of the input. Prefer this over manual inspection or generic JSON schema validators when you need x402-specific semantic checks (valid path format, positive price, POST method requirement).
Side effects
- Malformed route object (non-object input) causes validation error
- Route missing required x402 fields returns valid:false with populated missing_fields array
- Route with zero or negative price fails positive_price check
- Non-POST method fails the 'post' check
- Oversized route object exceeding 128 properties may be rejected
- Network or payment failure returns HTTP 402 if USDC payment is not completed
