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 indicating whether the new spec introduces breaking changes (boolean), a human-readable scope description, a list of removed operations with their paths, a count of removed operations, and the old and new version strings.
Example use cases
Pre-deployment API compatibility check
“Before I push this new API version to production, check if it breaks backward compatibility — here's my old OpenAPI spec and the new one I want to deploy, tell me if any endpoints were removed or changed in a breaking way.”
CI pipeline breaking change gate
“I'm running a CI check and need to know if the updated OpenAPI spec introduces any breaking changes compared to what's currently in production — can you compare the old spec and the new candidate spec and flag any removed paths?”
API version upgrade audit for consumers
“My API provider just sent me their updated OpenAPI spec — can you compare it to the version I'm currently integrated against and tell me if they removed any operations I depend on?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/openapi-breaking-change?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-use, no-signup check for OpenAPI breaking changes — specifically for detecting removed paths and methods. Prefer it over manual diffing tools or heavyweight API governance platforms when you need a lightweight, automatable, agent-friendly check with verifiable delivery and crypto micropayment billing.
Side effects
- Malformed or invalid JSON in either spec document causing parse failure
- Missing required 'new_spec' or 'old_spec' fields returning an error
- Specs with no version metadata resulting in empty version fields
- Payment failure via x402 protocol blocking request execution
- Semantic schema compatibility issues flagged in scope but not fully analyzed beyond path/method removal
