How this service works
Don't burn tokens on deterministic work. Go/no-go jobs first: payout preflight, text firewall (PII/secrets), budget check — then rails, calendars, finmath. x402 USDC on Base. UK + global. agent402.co.uk — not agent402.tools. $0.001–$0.002 USDC on Base. No API keys.
Output
Returns a JSON object with a boolean 'valid' field indicating whether the email has valid syntax, and a 'normalized' field containing the email in canonical lowercase form (e.g. {"valid": true, "normalized": "ops@example.com"}). No MX or DNS resolution is performed.
Example use cases
Pre-storage email sanitization
“Before I save this user's email 'John.DOE@Gmail.COM' to my database, can you normalize it to its proper lowercase canonical form?”
Deduplication before bulk mailing
“I have two email addresses, 'Alice@EXAMPLE.com' and 'alice@example.com' — can you normalize the first one so I can check if they're duplicates?”
Form input validation pipeline
“A user just submitted 'Support@MyCompany.CO.UK' in our signup form — can you check if the email syntax is valid and give me the normalized version?”
Technical details
Endpoint
POSThttps://agent402.co.uk/v1/normalize/emailWhen to prefer
Choose this endpoint when you need fast, cheap, deterministic email syntax normalization and canonicalization without any network-dependent MX or DNS resolution. Ideal for pre-storage sanitization, deduplication pipelines, or input validation where DNS checks are unnecessary or too slow. At $0.001 per call it is suitable for high-volume cleaning tasks.
Side effects
- Missing or empty email field returns an error response
- Malformed JSON body causes a 400-style error
- Completely unparseable strings (no @ symbol, no domain) may return valid: false
- Payment failure or missing x402 header results in 402 response blocking the call
