How this service works
Automated 8-gate pre-flight readiness auditor for x402 v2, Dexter gas floor, IETF MPP, MCP Streamable HTTP, A2A v0.3.0 agent cards, OASF records, and ERC-8004 identity.
Output
Returns a JSON object with a 'status' field (e.g. 'ok'), a 'data' object containing validation details about the email, and an 'roi_proof' object including a compression_ratio_pct value indicating processing efficiency.
Example use cases
Pre-registration email check
“Before I create the account, can you validate that 'sarah.jones@gmail.com' is a properly formatted and valid email address?”
Marketing list scrubbing
“I have a contact email 'bob.smith@acme.corp' — can you verify it's a valid email before we add it to our outreach list?”
Form submission validation
“A user just entered 'notanemail@@baddomain' in our signup form — can you check whether that's actually a valid email address?”

Endpoint
GEThttps://preflight.agentdiet.dev/v1/email-validator?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call email validation check integrated into an x402 micropayment workflow, especially in agent pipelines on the agentdiet.dev infrastructure where x402 payment rails are already established.
Side effects
- Missing or malformed email query parameter returns an error response
- Invalid or unparseable email string may return failed validation status
- Network timeouts or service unavailability return non-200 responses
- Payment failure via x402 protocol blocks the request before processing
