How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://rag-diet.agentdiet.dev settling in USDC on Base.
Output
Returns a JSON object with a status field ('ok') and a data object containing the verification result for the queried email address, along with an roi_proof object showing a compression_ratio_pct metric reflecting AgentDiet's context efficiency.
Example use cases
Pre-send email deliverability check
“Before I send this campaign, verify that sarah.jones@acmecorp.com is actually a valid and deliverable email address.”
User registration email validation
“A new user just signed up with the email mike.t@fakedomainn.xyz — can you check if that email is real before we create their account?”
CRM data quality audit
“I have a contact in my CRM with the email address hello@oldstartup.io — can you verify if that email address still exists and is deliverable?”
Technical details
Endpoint
GEThttps://rag-diet.agentdiet.dev/v1/email-verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call email validation check within an A2A or MCP agent workflow, especially when settling micropayments in USDC on Base via x402 protocol. Suitable for single-email spot checks rather than bulk batch validation.
Side effects
- Missing or malformed email query parameter returns an error response
- Invalid email format may return a negative validation result rather than an error
- Network or service unavailability returns a non-200 status
- Payment failure (x402) if USDC on Base is not provided or insufficient
