How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing the original email string, a boolean 'valid' field indicating whether it conforms to email address shape/syntax, and a schema identifier ('delx/util-is-email-shape/v1') for verifiable provenance.
Example use cases
Form input email sanity check
“Before I save this registration, can you check if 'john.doe@@company.com' is a valid email format?”
Bulk data cleanup pre-flight
“I've got a list of email addresses from an old database export — can you check if 'noreply#internal.corp' has valid email shape before I try to import it?”
Agent pipeline guard
“Before my agent sends an outreach email to 'alice_at_acme.io', can you verify that string is actually shaped like a real email address?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/is-email-shape?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call email syntax/shape check with no signup and verifiable delivery via x402 on Base or Solana USDC. Ideal for AI agents that need a trust-minimized, micropayment-gated validation primitive without standing up a subscription or managing API keys. Not a deliverability check — use this only for format/shape validation.
Side effects
- Missing 'email' field in request body returns an error
- Non-string input may cause a validation error
- Network or payment processing failure returns a 402 or 5xx error
- Ambiguous edge-case email strings (e.g. internationalized domains) may yield unexpected results
