Call when you cheaply reject obvious non-emails before enrichment. Returns valid boolean for $0.001 USDC via x402 on Base. Shape only—not MX, SMTP, or ownership proof.

Results are advisory; the caller owns budgets, auth, and production controls.","url":"https://api.delx.ai/api/v1/x402/is-email-shape","method":"POST","headers":{},"bodySchema":{"type":"object","properties":{"email":{"type":"string","description":"Input field: email."}}},"responseSchema":{"type":"json","example":{"email":"ops@delx.ai","valid":true,"schema":"delx/util-is-email-shape/v1"}},"example":null,"exampleRequest":null,"tags":["x402"],"displayCostAmount":"0.001","displayCostAsset":"USDC","priceDynamic":false,"priceHint":null,"priceStatus":"priced","priceSource":"probe","requiresHandshake":false,"reviewCount":0,"rating":{"score":"0.00","successRate":"0.00","reviews":0,"stars":null,"state":"unrated"},"availabilityStatus":"unknown","priceObserved":null,"sessionDeposit":null,"pricing":{"kind":"static","summary":"$0.001/call","primary":{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.001","per":"call","confidence":"exact"},"accepted":[{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.001","per":"call","confidence":"exact"}]},"paymentMethods":[{"uid":"pm_X9bApa406wrPSPT8XndpU","protocol":"x402","methodType":"crypto","chain":"base","mode":"charge","costAmount":"0.001","costPer":"request","priority":0,"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","unit":"request","depositMicros":null,"planRef":null}],"brandName":null,"brandSlug":null,"brandBaseUrl":null,"brandDocsUrl":null,"whatItDoes":"Validates whether a string has a valid email address shape (syntax only, no network checks)","exampleAgentPrompt":"Before we enrich this lead, can you check if 'john.doe@example.com' is even a valid email shape — just the format, no network lookup needed?","exampleUseCases":[{"title":"Pre-enrichment email gating","prompt":"Before spending credits on email enrichment for this contact list, check if 'not-an-email' has a valid email format so we can drop obvious garbage upfront."},{"title":"Form submission validation","prompt":"A user just submitted 'hello@' as their email on our signup form — can you check if that's a properly shaped email address before we try to send a welcome message?"},{"title":"Data pipeline input sanitization","prompt":"I'm about to process a batch of user records — can you validate whether 'user@@domain..com' looks like a real email address format so I can flag it as bad input?"}],"resultDescription":"A boolean field indicating whether the input string conforms to a valid email address shape.
