How this service works
Look up any phone number on WhatsApp: registration, business profile, profile photo and carrier. AI agents pay per request in USDC on Base with x402. No sign-up, no API key.
Output
A JSON object containing: whether the number has WhatsApp, the account type (personal or business), the country code and LID identity, linked device count and whether the account is cloud-hosted, the profile photo URL and content hash, the about/status text, and for business accounts: display name, description, categories, email, website(s), address, coordinates, timezone, business hours, cart enablement, verification level, member since date, and linked Facebook page details.
Example use cases
Verify business WhatsApp before outreach
“Before I send a WhatsApp message to +447911123456, can you check if it's actually a registered WhatsApp Business account and pull their display name and business category?”
Enrich CRM with WhatsApp business data
“I have a lead's phone number +5511987654321 — can you check their WhatsApp profile and tell me their business name, description, website, and hours so I can add it to our CRM?”
Detect hosted Cloud API business accounts
“Check the WhatsApp profile for +6281234567890 and tell me if it's a hosted WhatsApp Business Platform account — I want to know if they're using the Cloud API rather than a regular phone.”
Technical details
Endpoint
GEThttps://wtsp.dev/v1/profile/full?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, single-call WhatsApp profile enrichment including business details, photo, and device signals — particularly useful for lead enrichment, pre-outreach verification, and fraud screening. It requires no API key or sign-up, making it ideal for agent workflows that pay per use in USDC via x402. Prefer this over manual WhatsApp checks or partial lookup services when you need the full picture including hosted-account detection and business hour data in one response.
Side effects
- Phone number not registered on WhatsApp — hasWhatsApp returns false with no profile data
- Invalid or malformed phone number — returns 4xx error
- Privacy settings hide profile photo — picUrl returns null
- Privacy settings hide about text — aboutRestricted is true and about is empty
- Number is personal account — business fields are absent
- WhatsApp sends no device list — devices field is absent
- Payment failure via x402 — request blocked before reaching WhatsApp
- Rate limits or WhatsApp-side throttling — intermittent 5xx errors
