  1. MCP server for AI agents

    The MCP server speaks streamable HTTP, takes your API key as a bearer token and exposes every lookup as a tool, plus get_account for your balance and keys.

    Tool calls are billed exactly like REST calls: the same credit price, the same success billing and the same free repeats inside the cache window.

  2. Documentation, OpenAPI and llms.txt

    The documentation covers the base URL and authentication. A plain-text guide for agents is at https://lookvalid.com/llms.txt.

    The quickstart, API reference, MCP guide and error pages are in the docs sidebar.

  3. 14 lookups on one key

    One API key and one credit balance now cover these lookups. Each is a POST to its own path under https://YOUR_API_HOST.

    • Phone Numbering-Plan Validation at /v1/phone, 1 credit per valid number.
    • Country Calling Codes at /v1/country-code, 1 credit per lookup (an unknown code, country or name is free).
    • Email Domain Check at /v1/email-domain-check, 1 credit per address checked.
    • IP Intelligence at /v1/ip, 1 credit per lookup.
    • Phone Spam Check at /v1/phone-spam, 1 credit per number with complaints on record.
    • Link Safety Check at /v1/link-safety, 1 credit per URL checked (a check that cannot run is free).
    • Carrier Lookup (original carrier) at /v1/carrier-lookup, 1 credit per lookup (numbers outside the covered numbering plan areas are free).
    • VIN Decoder at /v1/vin-decoder, 1 credit per VIN that decodes (a VIN with no data is free).
    • Link-in-Bio Lookup at /v1/link-in-bio-lookup, 3 credits per resolved page (dead or empty pages are free).
    • Domain Authority at /v1/domain-authority, 10 credits per domain found in the rank data (an unranked domain is free).
    • Domain Age at /v1/domain-age, 2 credits per registered domain (unregistered domains are free).
    • Website Scraper at /v1/website-scraper, 10 credits per successful scrape (errors, empty and blocked pages are free).
    • Website Contacts Scraper at /v1/website-contacts-scraper, 10 credits per domain with contacts found.
    • Site Files Checker at /v1/site-files, 2 credits per site checked (a site that cannot be reached is free).

    Results are cached for each account for 7 days, so repeating a lookup inside that window costs nothing.
