Prospeo vs Icypeas (2026): Data, Pricing and API Compared

Icypeas is cheaper than Prospeo at every volume we priced, and it gets cheaper per email as you buy bigger blocks. Prospeo costs more but sells mobile numbers and a rep-facing app. Both meter every lookup. The numbers below come from each vendor's own pages, checked in September 2026.

Verdict

• Pick Icypeas if you know the name and the domain and want the cheapest verified email. A 10,000-credit month is $89, and 1M credits is a published $3,992 tier (Icypeas pricing, September 2026).
• Pick Prospeo if you need mobile numbers, a Chrome extension or CRM sync for reps. A mobile costs 10 credits, and a lookup that finds nothing costs nothing (Prospeo help center, September 2026).
• Pick neither if you pull data in code by filter and want a flat bill. Both are credit meters. LeadOcean fits that case and is covered below.

Side by side

Every cell links to the page it came from. "Not published" means the vendor prints no figure on the pages we checked.

Data and coverage

Icypeas quotes the larger database. Its features page says 575M business professionals, 62M company profiles and 1.8B emails (Icypeas features, September 2026). Prospeo's homepage says 280M leads and companies and 143M verified emails (Prospeo, September 2026).

Do not compare the two email figures directly. Icypeas counts addresses, and one person can hold several. Prospeo counts verified addresses. Neither vendor publishes how many people have an email.

Phones are the clearest gap. Prospeo sells a mobile finder, charged at 10 credits per mobile found with the email included (Prospeo help center, September 2026). Icypeas quotes 280M phone numbers, yet its pricing page lists Phone Finder as coming soon (Icypeas pricing, September 2026). Its email search response carries a phones array, but we found no phone price or phone route in the credit docs.

Search differs too. Prospeo search returns 25 results a page for 1 credit and carries no contact data, so you pay again to enrich (Prospeo API docs, September 2026). Icypeas Find People costs 0.02 credit per result, and counts are free (Icypeas docs, September 2026).

API and developer experience

Prospeo is one call. Icypeas is two. Prospeo's enrich endpoint answers in the same request and takes a name plus a company website, a LinkedIn URL or an email (Prospeo API docs, September 2026). Icypeas takes a first name, last name and domain, returns an _id, and you read the result later.

This is the Prospeo request, with placeholder data:

curl -X POST "https://api.prospeo.io/enrich-person" \
  -H "X-KEY: $PROSPEO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"only_verified_email":true,"data":{"first_name":"Jane","last_name":"Doe","company_website":"acme.com"}}'

This is the Icypeas request, then the poll for the result. Keep polling while the status is NONE, SCHEDULED or IN_PROGRESS:

curl -X POST "https://app.icypeas.com/api/email-search" \
  -H "Authorization: $ICYPEAS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"firstname":"Jane","lastname":"Doe","domainOrCompany":"acme.com"}'

curl -X POST "https://app.icypeas.com/api/bulk-single-searchs/read" \
  -H "Authorization: $ICYPEAS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"id":"ID_FROM_THE_FIRST_RESPONSE"}'

The Icypeas docs warn against the single route for many searches. Use bulk search instead (Icypeas docs, September 2026). Reading results is capped at 30 calls a minute, so a polling loop needs care.

Rate limits favour Prospeo on Pro and Icypeas on the entry plans. Prospeo allows 30 enrich calls a second on Pro but only 5 on Starter and Growth, with daily caps of 2,000 and 5,000 (Prospeo rate limits, September 2026). Icypeas lists 10 calls a second on email search for every plan and says limits can change at any time.

Free API access on Prospeo is unsettled. Its pricing table shows no public API on Free. Its help center lists limited API access with 50 requests a day (Prospeo help center, September 2026). Test a free key before you plan around it.

Both have a hosted MCP server. Prospeo has 8 tools and OAuth 2.0 or an API key. Icypeas has 21 tools and signs in with your API key (Prospeo MCP docs, September 2026; Icypeas MCP guide, September 2026).

Pricing

Icypeas costs less at both sizes. Both tools charge per found email, so the arithmetic assumes every lookup finds one. Your real bill depends on your find rate.

At 10,000 records a month (verified emails, 1 credit each):

• Prospeo, monthly: the cheapest mix we priced from the published tiers is Growth at $99 for 5,000 credits plus the 5,000-credit add-on at $90. That is $99 + $90 = $189 a month for 10,000 credits. One Pro seat is $249 for 15,000 credits (Prospeo pricing, September 2026).
• Prospeo, billed yearly: one Pro seat is $2,241 for 180,000 credits upfront, about $187 a month. Unused credits expire at the end of the year.
• Icypeas, monthly: Advanced is $89 for 10,000 credits (Icypeas pricing, September 2026).
• Icypeas, billed yearly: Advanced is $890 for 120,000 credits, $74.17 a month. Prices are plus VAT.

At 1M records a month:

• Prospeo, monthly: no single tier reaches 1M. (1,000,000 - 350,000) / 15,000 = 43.3, so 44 Pro seats at $249 = $10,956. Add the 350,000-credit add-on at $3,500. That is 1,010,000 credits for $14,456 a month (Prospeo pricing, September 2026).
• Prospeo, billed yearly: (1,000,000 - 500,000) / 180,000 = 2.8, so 3 Pro seats at $2,241 = $6,723. Add the 500,000-credit yearly add-on at $4,500. That is $11,223 once for 1,040,000 credits upfront. It covers one month of 1M, not twelve.
• Icypeas, monthly: the published 1,000,000-credit tier is $3,992 a month, or $0.003992 a credit.
• Icypeas, billed yearly: 12M credits cost $39,920, which is $3,326.67 a month (Icypeas pricing, September 2026).

At 1M emails a month, Prospeo costs about 3.6 times as much on monthly billing: $14,456 against $3,992. The volume tiers on Icypeas sit in a credit selector the page text hides, so re-check them on the live page before you commit.

Mobile numbers change the maths on Prospeo. 1M mobiles is 10M credits, and no public plan sells that, so there is no public 1M price for mobiles. Icypeas has no phone price at all.

Where Prospeo wins

• Mobile numbers. It is the only one of the two with a priced mobile finder, at 10 credits per mobile found (Prospeo help center, September 2026).
• A one-call API. Enrich answers in the same request, and bulk enrich takes up to 50 records. You do not poll.
• Tools for reps. A Chrome extension on every plan, plus HubSpot and Salesforce sync on Growth and Pro (Prospeo pricing, September 2026).
• A free plan. 100 credits a month at $0. Icypeas offers 50 credits once.
• Higher Pro throughput. 30 enrich calls a second and 500,000 a day on Pro.

Where Icypeas wins

• Price. It is cheaper at 10,000 and at 1M records, and its own price per credit falls to $0.003992 at 1M.
• Rollover. Unused credits never expire, even after a downgrade or cancellation (Icypeas pricing, September 2026). Prospeo credits expire each cycle.
• No seats. Pricing does not scale with headcount. Prospeo sells per user.
• A bigger MCP toolset. 21 tools against 8.
• Verification as a product. A verifier costs 0.1 credit per email checked (Icypeas docs, September 2026).

If you need volume through an API

Both tools above bill per email found, so a large pull costs more the more you find. LeadOcean is built for the other case. Pro is $499 a month, flat, with no credits and no per-record price. Free gives you 1,000 records one-off with no card, on the same API and MCP server.

You search by filter, not by name, over REST or a 12-tool MCP server. Export up to 50,000 rows per request with POST /v1/exports. A very large month is paced down past the fair-usage line, not cut off. If you only hold a name and a domain, Icypeas is the more direct fit.
