How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://mcp-gateway.agentdiet.dev settling in USDC on Base.
Output
Returns a JSON object with a status field ('ok') and a data object containing information about whether the queried email is disposable, along with an roi_proof metadata field indicating compression ratio. The data payload indicates the classification result for the provided email address.
Example use cases
Block fake signups on registration
“Before I let this user register, check if their email 'temp1234@guerrillamail.com' is a disposable address — I don't want throwaway accounts on my platform.”
Screen leads before CRM entry
“We just got a new lead with the email 'john.doe@yopmail.com' — can you tell me if that's a real email or a temporary one before we add them to our CRM?”
Validate bulk email list quality
“I have a sign-up email 'randomuser@trashmail.me' — is this a known disposable email provider so I can decide whether to flag this account?”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/disposable-email?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call disposable email detection check settled in USDC via x402, without managing an API subscription. Prefer it for agent pipelines where deterministic, single-email validation is needed at registration or lead qualification time, especially in crypto-native or x402-compatible agent workflows.
Side effects
- Missing or malformed email query parameter returns an error or empty data
- Unknown or novel disposable email domains may not be detected
- Network or payment failure results in no response or 402 payment required
- Rate limiting or USDC payment settlement failure blocks the request
