How this service works
Prysm sells paid, agent-ready provider capabilities over x402 on Base mainnet using USDC.
Output
Returns a JSON object with email validation details including deliverability status, format validity, SMTP check results, whether the domain is free or disposable, MX record presence, and a quality/risk score for the email address.
Example use cases
Lead quality check before CRM import
“Before I import this list of leads, can you check if the email address sarah.johnson@startupco.io is real and deliverable — I want to know if it passes SMTP checks and whether the domain is legitimate?”
Sign-up fraud detection
“A new user just registered with the email temp123@mailinator.com — can you check whether that's a disposable or throwaway email address so I can decide whether to flag the account?”
Bounce risk assessment for email campaign
“I'm about to send a newsletter campaign — can you validate marketing@bigcorp.com and tell me its deliverability score and whether the MX records are set up correctly?”
Technical details
Endpoint
POSThttps://prysm-kappa.vercel.app/api/v1/providers/abstract_emailWhen to prefer
Choose this endpoint when you need a quick, pay-per-call email validation without managing Abstract API credentials yourself — ideal for agents making occasional lookups via x402 micropayments on Base in USDC. Prefer it over direct Abstract API calls when you want a single credentialed gateway that handles billing automatically.
Side effects
- Invalid or malformed email input returns a validation error
- Unrecognized operation name returns an allowlist error
- Upstream Abstract API timeout returns a 504 or partial response
- Payment not settled via x402 returns a 402 Payment Required response
- Rate limiting by the underlying provider may return a 429
