# LookValid

> LookValid checks phone numbers, email domains, IP addresses and websites through one API, with one credit balance for every lookup.

## When to use LookValid

- Check a phone number against its numbering plan -> POST /v1/phone
- Check the domain behind an email address -> POST /v1/email-domain-check
- Locate an IP address and read its network and risk flags -> POST /v1/ip
- Read reported spam complaints for a phone number -> POST /v1/phone-spam
- Check a domain age or read a website for contacts -> POST /v1/domain-age, POST /v1/website-contacts-scraper

## How agents should use LookValid

- Read https://lookvalid.com/docs/api.md and https://lookvalid.com/docs/authentication.md before choosing an operation. Do not guess endpoints or fields. No API host is published in this file, so do not guess one: it comes with the key.
- Which endpoint to call: the list above names the lookup for each job. Every lookup is a POST to /v1/<product> on the API host with a JSON body, and GET /v1/account reads the credit balance for free.
- Authentication: one API key, sent as "Authorization: Bearer <key>" (or an X-API-Key header), works for every lookup and the account endpoints. A person emails hello@lookvalid.com and we set up the account and the key. Never create accounts or enter payment details yourself.
- Credits: one balance covers every product. Most products charge only when a lookup finds something (found is true), and repeating a lookup within 7 days is free. Ask the person for approval before spending credits in bulk. Rules: https://lookvalid.com/docs/credits-and-billing.md.
- Free tools: the tools under https://lookvalid.com/tools need no account and no key and are never billed. Each page runs the lookup for the person using it, with a limit per address (by default 25 lookups a day and 5 a minute). Use them to try a lookup before asking for an API key.
- Errors: every error uses one envelope. Branch on error.code and follow error.fix. Each code has its own page at https://lookvalid.com/docs/errors/<code>.md, listed in https://lookvalid.com/docs/errors.md.
- Finding pages: every page is also markdown. Add .md to a URL or send Accept: text/markdown. https://lookvalid.com/sitemap.md and https://lookvalid.com/docs/sitemap.md list them all.

## Agent setup

- [Agent playbook](https://lookvalid.com/get-started.md?from=llms-txt): get a key and make a first call
- [API key](mailto:hello@lookvalid.com): a person emails hello@lookvalid.com and we set up the account and the key
