Clay vs FullEnrich (2026): Data, Pricing and API Compared

Clay and FullEnrich overlap on one job, finding emails and phones for a list of people, and differ on almost everything else. Clay is a workflow table that calls 150+ data partners. FullEnrich is an enrichment service that asks 25+ sources in turn and bills by the credit. Neither publishes a price at 1M records a month.

Verdict

• Pick Clay if a RevOps team will build and run workflows in a table. You get waterfalls, AI research columns and CRM sync in one place, and you pay a plan fee built from two meters.
• Pick FullEnrich if you want one API that returns a work email and a mobile for each contact. You pay per credit, only for what it finds, and the price per field is easy to read.
• Pick neither if you need millions of records a month in code or through an agent. Both stop at a public ceiling, and above it you talk to sales. LeadOcean sells one flat $499 a month Pro plan with a 100 requests per second limit.

Side by side

Prices are monthly list price first, billed-yearly figure after it. Both vendors change plans often, so check the pricing page before you buy.

Data and coverage

Clay publishes no database size. For enrichment, its coverage is the coverage of whichever provider answers. The pricing page counts 150+ data partners. You choose the order, and Clay runs each one in turn until a column fills (Clay pricing, September 2026).

That design has a cost and a benefit. Clay publishes no email or phone find rate, so you cannot size it before you run a sample. But you can add a niche provider for one region or one industry in a single column.

FullEnrich also runs a waterfall, but it picks the sources for you. Its pricing page lists 25+ sources and full access to 800M people and 50M companies for search (FullEnrich pricing, September 2026). The homepage and MCP page carry a customer quote about 1.6B contacts. That quote is about one customer's coverage, not the size of FullEnrich's database.

FullEnrich states about an 80% find rate on work emails on average. It also says about 30% of raw data is removed by verification (FullEnrich pricing.md, September 2026). Both figures are FullEnrich's own claims and we have not tested them.

On phones, FullEnrich puts a price on the mobile number: 10 credits when it finds one, and nothing for a miss or a landline (FullEnrich docs, September 2026). Clay's free plan has no phone enrichment. The credit cost of a Clay phone lookup sits inside the table next to the enrichment, not on a public page.

FullEnrich documents four email statuses: deliverable, high probability, catch-all and invalid (FullEnrich docs, September 2026). In Clay the status depends on the provider that answered.

API and developer experience

Both tools have an API, but they sit at different layers. Clay's Public API runs routines, which are functions you build in the Clay table UI. FullEnrich's API is the product: you post contacts, it returns emails and phones.

Clay uses a clay-api-key header. A run is asynchronous. You start it, get a routine_run_id, then poll for results until the endpoint returns 200. A run takes 1 to 100 items (Clay developer docs, September 2026).

curl --request POST \
  --url "https://api.clay.com/public/v0/routines/function:t_abc123/run" \
  --header "Content-Type: application/json" \
  --header "clay-api-key: $CLAY_PUBLIC_API_KEY" \
  --data '{"items":[{"id":"row-1","inputs":{"domain":"acme.com"}}]}'

The Public API and CLI are on every Clay plan, Free included. Search volume is capped by plan: Free gets 50 results per request and 100 a month (Clay docs, September 2026). The HTTP API column, which calls other APIs from a table, needs Growth ($495 a month) or Enterprise.

FullEnrich uses Bearer auth (FullEnrich docs, September 2026). Bulk enrichment takes up to 100 contacts. You pick the fields with enrich_fields, and you get results on a webhook or by polling (FullEnrich docs, September 2026).

curl --request POST \
  --url https://app.fullenrich.com/api/v2/contact/enrich/bulk \
  --header "Authorization: Bearer $FULLENRICH_API_KEY" \
  --header "Content-Type: application/json" \
  --data '{
    "name": "Sales Operations in London",
    "webhook_url": "https://example.com/webhook",
    "data": [{
      "first_name": "Jane", "last_name": "Doe", "domain": "acme.com",
      "enrich_fields": ["contact.work_emails", "contact.phones"]
    }]
  }'

Rate limits differ in kind. FullEnrich publishes a number: 60 calls a minute, which at 100 contacts a call is 6,000 contacts a minute. Over the limit you get HTTP 429 with the code error.rate.limit (FullEnrich docs, September 2026).

Clay enforces a per-workspace limit and publishes no number. You find it by hitting a 429, which carries a Retry-After header (Clay developer docs, September 2026). For the HTTP API column you set your own limit per column.

Pricing

Clay builds a plan from two tiers: Actions and Data Credits. Actions pay for the work, and every enrichment uses one. Data Credits pay for the data. FullEnrich sells one credit pool, and each field you find spends credits.

At 10,000 records a month

Take 10,000 work emails. FullEnrich charges 1 credit per work email found, so 10,000 credits. The 10,000-credit monthly tier is $499. Billed yearly, 120,000 credits a year is $454 a month ($5,448 a year) (FullEnrich pricing.md, September 2026).

For Clay, use its worked example of 0.5 credit per email find. That is 5,000 Data Credits and 10,000 Actions. The 15,000 Action tier is $60 and the 6,000 credit tier is $290, so $60 + $290 = $350 a month. Billed yearly it is $315, about 10 percent less (Clay pricing, September 2026).

On this example Clay costs less than FullEnrich. But 0.5 credit is an example, and the real number varies by provider. Clay's own doc says a fully enriched record typically costs 6 to 20 Data Credits (Clay docs, September 2026). At 6 credits, 10,000 records need 60,000 credits, above the 50,000 top self-serve tier.

Mobiles change the picture on the FullEnrich side. 10,000 mobiles at 10 credits is 100,000 credits, the top monthly tier at $3,500. Clay does not publish a credit cost for a phone lookup, so there is no figure to set against it.

At 1M records a month

Neither vendor publishes a 1M price, so we do not show one.

For Clay, 1M lookups need 1M Actions, and Actions cannot be bought as top-ups. The largest public Action tier is 200,000 a month. The top Growth tier is 200,000 Actions at $850 plus 50,000 credits at $2,125, which is $2,975 a month, or $2,678 billed yearly. At 0.5 credit per email, 50,000 credits cover about 100,000 lookups. Above that is an Enterprise quote (Clay pricing, September 2026).

For FullEnrich, 1M work emails need 1M credits. The top public monthly tier is 100,000 credits for $3,500, which covers a tenth of the volume. The yearly toggle stops at 1,200,000 credits a year for $37,800 billed yearly. That is 100,000 credits a month on average. Above the top tier, FullEnrich says contact sales (FullEnrich pricing.md, September 2026).

Both are quote-only at 1M. Ask each for a number in writing, with your mix of work emails and phones, before you plan around either.

Where Clay wins

A table you can run without code

Clay is a spreadsheet where ops people can build a workflow. They edit columns, set run conditions and watch each row run. FullEnrich has no table to build in. A non-technical team that wants to own the workflow should stay in Clay.

AI research and many sources

Claygent runs research per row, and it is on every Clay plan including Free (Clay pricing, September 2026). Clay also reaches 150+ providers, so a long-tail source is one column away. FullEnrich returns contact data and does not run research.

Cheaper emails at low volume

On the 0.5 credit example, 10,000 emails cost $350 on Clay against $499 on FullEnrich. A no-result enrichment also costs no Data Credits and no Actions (Clay pricing, September 2026). That edge depends on the provider you pick.

Where FullEnrich wins

One call, one price per field

FullEnrich prices each field: 1 credit for a work email, 3 for a personal email and 10 for a mobile. Misses cost nothing (FullEnrich docs, September 2026). You can work out a bill before you send the request, which is harder on Clay's two meters.

A published rate limit and an API-first design

FullEnrich tells you the limit: 60 calls a minute and 100 contacts per call. You can plan a batch around that. The API, MCP, search and bulk CSV are on every plan, including the free trial (FullEnrich pricing.md, September 2026).

A cheaper way to start

FullEnrich Pro starts at $29 a month. Clay's paid entry is Launch at $185 a month. If you need a few hundred verified contacts a month, the FullEnrich entry plan costs a fraction of Clay's.

If you need volume through an API

LeadOcean is a data API and MCP server with 693M people and 63M companies in one dataset. The Free plan gives you 1,000 records, one-off, with no card. Pro is $499 a month flat, with no credits and no per-record price. It runs over REST and MCP, with a 100 requests per second limit per key and bulk CSV export through POST /v1/exports, up to 50,000 rows per request. It has no table builder or rep workspace, so it fits teams that call data from code, not teams that build workflows by hand.
