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 containing: a boolean `shape_valid` indicating whether the error object is well-formed, a `missing_fields` array listing any absent required fields, a `status` string ('pass' or 'fail'), the operation name, schema identifier, and an evidence block with a SHA-256 hash of the input, a `retained: false` flag confirming no data is stored, and an `external_calls: 0` count.
Example use cases
Agent pipeline error gate
“Before I route this error from my agent to the next step in my workflow, check if it has a valid shape and tell me which fields are missing, if any — here's the error: {"type": "retrieval_error", "details": null}.”
Debug malformed agent output
“My agent keeps returning errors that downstream services reject — can you run a shape check on this error object and tell me if it's valid or what's wrong with it: {"error_code": 500}?”
QA test for agent error format
“I'm testing my agent's error handling — please validate this error object against the expected schema and confirm whether it passes the shape check: {"message": "rate limit exceeded", "retryable": true, "source": "llm_provider"}.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/agent-result-error-shape-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, verifiable, privacy-safe check that an agent-produced error object conforms to the expected structural schema — especially in automated pipelines where you need cryptographic proof (SHA-256 hash) that the input was processed without retention or external calls. Prefer it over general-purpose JSON validators when you specifically need the Delx agent error schema contract and an auditable evidence record.
Side effects
- Input exceeds 128 properties — request rejected
- Non-object value provided for `error` field — schema validation error
- Malformed JSON body — parse error returned
- Payment failure via x402 — 402 response with payment details
- Network timeout — no response from endpoint
