How this service works
Source-backed API reports for wallet-enabled agents. Pay per successful call in Base USDC.
Output
Returns a JSON object with a 'status' field (e.g. 'ok') and an 'evidence_receipt' containing a SHA-256 hash of the preflighted transaction, serving as a cryptographic record that the request was checked against spend policy before execution.
Example use cases
Pre-authorize a payment request
“Before submitting that payment POST with the JSON body, run it through the Vino & Views preflight so I can confirm it's within the approval ceiling and get the SHA-256 evidence receipt.”
Validate a form submission before sending
“Can you preflight this PATCH request with the form-data body through Vino & Views to make sure the transaction type and method are compliant before I actually send it?”
Audit trail for automated agent actions
“My agent is about to PUT some data via JSON — run a Vino & Views preflight on it first so we have an evidence receipt logged before the real call goes out.”
Technical details
Endpoint
POSThttps://api.vinoandviews.online/v1/tx-preflight?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, read-only safety check on a state-changing HTTP request before executing it — especially in agentic workflows where spend policies, approval ceilings, or audit trails are required. It is ideal as a pre-execution gate in automated pipelines handling payments or sensitive mutations.
Side effects
- Missing required 'input' object returns validation error
- Invalid HTTP method (must be POST, PUT, or PATCH) causes rejection
- Unsupported bodyType value causes schema validation failure
- Malformed body object may result in policy evaluation failure
- Request exceeds spend ceiling, returning a denial verdict
- Network timeout or service unavailability returns non-200 status
