What is Clay?
Clay is a table-based workspace where each row is a lead and each column is an enrichment, a lookup or an AI step. Its site describes access to 200+ data providers, waterfall enrichment across several of them, and workflows that push the finished rows to a CRM or a sequencer.
People use it to build a list, fill in emails and phone numbers from whichever providers have them, and then decide who is ready to contact. Its pricing page lists phone number enrichment on the Launch plan.
Who it’s for
Clay suits the person who builds lists for other people to call: a GTM engineer, an outbound agency or a RevOps team. Each row is a lead and each column is one lookup, so you can try several data providers on the same row, add your own API calls and decide what is ready before anything reaches a rep. It rewards someone who is comfortable designing a table.

Where Clay fits in your calling
A Clay table often ends with a mobile phone column filled by a waterfall of providers, and any of them can return a number nobody will answer. Adding the check as one more column, before the row is pushed to a dialer or sequencer, keeps those out.

Frequently asked questions
Clay is a table-based workspace where each row is a lead and each column is an enrichment, a lookup or an AI step. Its site describes 200+ data providers, waterfall enrichment across several of them, and workflows that push finished rows to a CRM or a sequencer.
It suits whoever builds lists for other people to call, such as a GTM engineer, an outbound agency or a RevOps team. It rewards someone comfortable designing a table. Reps who want a screen to start dialing from will not find one, because Clay is not a dialer.
Its pricing page lists a Free plan at $0, Launch from $167 a month and Growth from $446 a month on annual billing (monthly billing is $185 and $495), and a custom Enterprise plan. The Free plan includes 500 actions and 100 data credits a month. It also says you can bring your own API key on every plan.
The Free plan gives 500 actions and 100 data credits a month, and caps tables at 200 rows. Its pricing page lists HTTP API integrations on Growth, not on Free, so a Free table cannot call the Will This Person Answer API.
Yes. Its docs describe an HTTP API column that calls any external API per row using GET, POST, PUT or DELETE and reads fields from the response. Its pricing page lists HTTP API integrations under the Growth plan, not the cheaper ones.
Phone number enrichment is listed on its Launch plan. Waterfall enrichment tries several data providers in turn to fill a field, so one column can return a number from whichever provider has it. Clay itself does not place calls.
Its integrations page lists CRMs such as Salesforce, HubSpot, Pipedrive and Dynamics 365, data sources like ZoomInfo, Apollo.io and Crunchbase, and sending tools such as Outreach, Salesloft, Lemlist and Instantly. It also lists Snowflake, Airtable and several AI model providers.
No. Clay calls the Will This Person Answer API from an HTTP API column that you set up yourself. If you would rather not, export the table to CSV and upload that. It checks US phone numbers only, with 250 contacts free and no card required.
After your phone enrichment columns, add an HTTP API column and POST to the analyze endpoint. Send first name, last name and the phone column as a one-row contacts array, with your API key in the Authorization header. Save the key as a workspace HTTP API (Headers) account. One credit checks one contact.
Add the outcome and reason fields from the response as their own Field Paths, so each row shows High chance, Low chance or Bad data. Filter before the push: send High chance rows to your dialer, Low chance to a multi-channel sequence, and keep Bad data and Email & LinkedIn rows to email.
