Limits 1lookup states
- API access needs a paid plan, so an account on the free plan cannot call the API. Source
- Lookups that fetch live data can take seconds on a first call, and its guide advises a client timeout above 60 seconds for them. Source
- Enrichment and intelligence products draw from 2 up to 86 credits a lookup, so the price of one call depends on which product it is. Source

- Phone Numbering-Plan Validation: Validates a number against its numbering plan: format, country, number type and area. It does not ping the line. About $2.00 to $4.95 for 1,000 billed lookups across the plans.
- Email Domain Check: Checks the domain behind an address: whether it can receive mail, how its DNS is set up, and what kind of provider it is. It does not test whether one mailbox exists. About $2.00 to $4.95 for 1,000 billed lookups across the plans.
- IP Intelligence: Locates an IP address and reads its network and risk flags. About $2.00 to $4.95 for 1,000 billed lookups across the plans.
- Phone Spam Check: Reads complaint records on file for a number. About $2.00 to $4.95 for 1,000 billed lookups across the plans.
- Domain Age: Registration, last update and expiry dates, registrar and age in days for a domain, from the registry's public RDAP service. About $4.00 to $9.90 for 1,000 billed lookups across the plans.
- Domain Authority: A 0 to 100 authority score for a domain, with every input shown: its Common Crawl web graph harmonic centrality and PageRank positions and its Majestic Million rank and referring subnets. Only domains inside the top of the open rank lists are scored; an unranked domain is not proof of low authority. It is a link-graph score, not Moz or Semrush authority. About $19.99 to $49.50 for 1,000 billed lookups across the plans.
- VIN Decoder: Decodes a 17-character vehicle identification number with the US NHTSA vPIC service: model year, make, model, trim, body, engine, drivetrain, assembly plant and the safety equipment NHTSA has on record. The check digit is verified before NHTSA is called. Empty fields mean NHTSA has no data, not that the feature is missing. About $2.00 to $4.95 for 1,000 billed lookups across the plans.
- Link-in-Bio Lookup: Fetches a public link-in-bio page and returns its profile title, description and outbound links. About $6.00 to $14.85 for 1,000 billed lookups across the plans.
- Website Scraper: Fetches a public web page and returns its title, metadata, readable text and links. About $19.99 to $49.50 for 1,000 billed lookups across the plans.
- Website Contacts Scraper: Reads a domain's public pages and returns the email addresses, phone numbers and social profile links they publish. About $19.99 to $49.50 for 1,000 billed lookups across the plans.
