How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://status.agentdiet.dev settling in USDC on Base.
Output
Returns a JSON object with a 'status' field ('ok' or error), a 'data' object with validation details, and a 'roi_proof' object containing a 'compression_ratio_pct' value (e.g. 91.4) indicating context distillation efficiency for the request.
Example use cases
Pre-send email validation for outreach
“Before I send this campaign, can you validate whether contact@acmecorp.com is a real, reachable email address using an MX check?”
Agent workflow email gating
“I want to make sure we only process leads with valid emails — can you run an MX check on leads@startup.io before we move them to the next step?”
Validate email input from a web form
“A user just submitted john.doe@techfirm.co as their email on signup — can you verify that address is valid and deliverable before we create their account?”
Technical details
Endpoint
GEThttps://status.agentdiet.dev/v1/mx-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call ($0.005 USDC) email MX validation that also returns a compression ROI proof metric, particularly within agent-to-agent (A2A) or bot-to-agent (B2A) workflows on the Base blockchain using x402 payment protocol. Best for agentic pipelines that need deterministic email validation with micropayment settlement.
Side effects
- Missing or malformed email query parameter returns an error status
- Invalid domain with no MX records returns failed validation
- Network timeout reaching the AgentDiet status node
- Payment failure via x402/USDC settlement blocks the request
- Unsupported HTTP method returns a schema validation error
