Delx X402 Discovery Parity Check
x402
Delx X402 Discovery Parity Check is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).
Verifies that tool lists across catalog, OpenAPI, runtime, and portfolio sources are consistent and complete, returning a parity result with missing tool details.

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 counts of tools per source, a boolean parity flag indicating whether all sources are in sync, and a 'missing' breakdown per source listing any absent tools. Also includes an evidence block with the input SHA256 hash, a retained=false flag confirming no data retention, and the operation name.
Example use cases
Agent tool registry audit
“I want to make sure my agent's tool catalog matches what's actually running at runtime. Here are my catalog tools: ['search', 'summarize', 'translate'], OpenAPI tools: ['search', 'summarize'], runtime tools: ['search', 'summarize', 'translate'], and portfolio tools: ['search', 'summarize', 'translate']. Run a parity check and tell me which source is missing tools.”
Pre-deployment tool consistency check
“Before I deploy my new agent version, verify that these tool lists are fully consistent — catalog: ['pay', 'invoice', 'report'], OpenAPI: ['pay', 'invoice'], runtime: ['pay', 'invoice', 'report'], portfolio: ['pay', 'invoice', 'report']. I need to know if anything is missing from OpenAPI before going live.”
X402 discovery source sync validation
“I'm debugging a tool discovery issue and need to find which tools are out of sync. My catalog has ['extract', 'enrich', 'classify'], OpenAPI has ['extract', 'enrich', 'classify'], runtime has ['extract', 'enrich'], and portfolio has ['extract', 'enrich', 'classify']. Run the parity check and show me exactly what's missing from the runtime source.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/x402-discovery-parity-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a cryptographically-verifiable, stateless parity check across x402 tool discovery sources (catalog, OpenAPI, runtime, portfolio) with proof of no data retention. Prefer it over manual diffing or custom scripts when you need a structured missing-tools report per source and an auditable SHA256 input hash for compliance or debugging.
Side effects
- Malformed array items exceeding 8192 characters return validation errors
- Exceeding 256 items per array may result in rejection
- Empty arrays may produce trivially-passing parity that masks real gaps
- Payment failure via x402 returns 402 before processing begins
