How this service works
Pay-per-call x402 APIs for autonomous agents on Base USDC: API compatibility analysis, bounded HTTP/JSON workflows, URL evidence analysis, crypto price consensus, and agent/MCP readiness checks.
Output
Returns a boolean 'pass' indicating whether the schema change is backward compatible, a 'signature' string summarizing the comparison, and a 'breaking_changes' array listing each identified incompatibility between the current and previous schema versions.
Example use cases
Pre-deployment schema safety check
“Before I push this new version of my agent tool schema live, can you compare it against the previous version and tell me if there are any breaking changes that would break existing callers?”
CI pipeline compatibility gate
“I'm running a CI check — compare these two MCP schema snapshots and tell me if the update passes backward compatibility or fails with breaking changes so I can block the merge.”
Agent tool upgrade risk assessment
“I want to upgrade my tool's schema but I'm not sure if it'll break the agents already using it — can you diff the current schema against the old one and list any breaking changes?”

Endpoint
POSThttps://genesis-agent-tools.genesisagenttools.workers.dev/api/mcp-schema-drift?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a programmatic, pay-per-call compatibility check between two MCP or JSON-schema versions without standing up your own diffing infrastructure. Particularly useful in agent pipelines and CI/CD workflows where you want a cryptographically signed pass/fail result and an explicit list of breaking changes, rather than a qualitative diff. Ideal for autonomous agents managing their own tool registries and needing to gate schema upgrades safely.
Side effects
- Missing 'current' or 'previous' fields returns a validation error
- Malformed or non-object schema inputs may cause parsing failure
- Payment not included or insufficient triggers 402 response requiring x402 USDC payment on Base
- Very large schema objects may hit payload size limits
- Ambiguous schema formats (non-standard JSON Schema) may produce incomplete breaking change detection
