How this service works
309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.
Output
Returns a JSON object indicating whether the provided email address string passes syntax validation, with an 'ok' boolean and a 'paid' confirmation field indicating the x402 micropayment was processed.
Example use cases
Form input validation before submission
“Before I save this user registration, can you check if 'alice..smith@domain..com' is a valid email format?”
Batch onboarding data quality check
“We imported a CSV of contacts and one of the emails looks weird — can you check if 'user@-invalidhost.org' passes basic email syntax validation?”
Catching typos in user-entered emails
“A user just typed 'bob@gmailcom' into our signup form — can you tell me if that's a properly formatted email address?”
Technical details
Endpoint
GEThttps://x402-toolbox.shablony-pro.workers.dev/util/email-syntax-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, no-signup, pay-per-call email syntax check with no API key overhead — ideal for AI agents operating autonomously via x402 USDC micropayments on Base, where you want deterministic validation without maintaining service credentials.
Side effects
- Missing or empty email string input returns validation failure
- Malformed request schema results in error response
- x402 payment failure prevents tool execution
- Network timeout on the Cloudflare Worker edge
