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: the schema name that was checked, a boolean 'supported' flag, an overall 'pass' or 'fail' status, and a verifiable evidence block containing an input SHA-256 hash, a flag confirming no data retention, and a count of zero external calls made. Identifies the operation as 'delivery_contract:agent_result_schema_version_check'.
Example use cases
Pre-flight schema compatibility check
“Before I process this agent output, can you verify that schema 'myapp/agent/v3' is one of the supported versions: ['myapp/agent/v1', 'myapp/agent/v2', 'myapp/agent/v3']?”
CI pipeline schema validation gate
“In my deployment pipeline I need to confirm that the schema 'acme/results/v2' is supported — the supported list is ['acme/results/v1', 'acme/results/v2']. Can you run the version check and tell me if it passes?”
Multi-version agent orchestration routing
“I'm routing agent results and need to know if schema 'orchestrator/task-result/v5' is in this supported list: ['orchestrator/task-result/v4', 'orchestrator/task-result/v5', 'orchestrator/task-result/v6']. Please check and return whether it's supported.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/agent-result-schema-version-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, verifiable, pay-per-result check that a specific agent result schema version string is in a given supported list — especially in agentic pipelines where auditability (SHA-256 evidence, no data retention, zero external calls) matters. Prefer it over ad-hoc string matching when you need a tamper-evident, cryptographically evidenced result you can log or pass downstream.
Side effects
- Schema string exceeds 8192 character limit — request rejected
- Supported array exceeds 256 items — request rejected
- Malformed JSON body — 400 error
- Schema not found in supported list — result.supported returns false, status returns 'fail'
- Network or service unavailability — 5xx error
