How this service works
DDG agent-payable service request
Output
Returns a JSON object with an 'ok' boolean field indicating whether the preflight check passed, along with any validation details about the submitted email payload.
Example use cases
Pre-send email payload validation
“I'm about to send a transactional email via a POST request with a JSON body — can you do a preflight check on the payload to make sure everything looks correct before I actually send it?”
Catch malformed email body early
“Run a preflight validation on this email request body before I submit it — I want to make sure the JSON is well-formed and will be accepted, not rejected mid-send.”
Automated pipeline email pre-check
“In my automated email pipeline, before each send step, preflight the outgoing email payload using POST with JSON body type to catch any issues before they cause delivery failures.”

Use this endpoint when you need a lightweight, machine-payable preflight validation step for email payloads before committing to a full send operation, especially in automated agent pipelines where catching errors early is critical and the cost per check is minimal ($0.01 USDC).
Side effects
- Missing required fields (input or output objects) returns a 400-level error
- Invalid bodyType enum value causes schema validation failure
- Malformed JSON body results in parse error response
- Payment not included or insufficient USDC causes 402 Payment Required
- Network timeout if the endpoint is temporarily unavailable
