The Prospeo alternative with one flat price

Prospeo is an email and mobile finder sold per user on credits, with a REST API and an MCP server. LeadOcean is one data layer you call over REST or MCP at one flat price. If you pull data in code or through an agent, LeadOcean is cheaper past roughly 30,000 lookups a month on monthly billing and has no meter. If your reps prospect in a Chrome extension, keep Prospeo.

Why teams switch from Prospeo

A credit on every lookup

One verified email costs 1 credit and one mobile costs 10. Company enrichment costs 1 credit, and so does each page of up to 25 search results (Prospeo help center, September 2026). A mobile-heavy pull burns credits ten times faster than an email-only one.

The API limits depend on the plan

Prospeo's own sources disagree on Free plan API access. The pricing table shows no Public API and no rate limits on Free. The help center lists limited access at 1 request a second, 20 a minute and 50 a day (Prospeo rate limits help article, October 2026). The API docs intro says free API access for all users (Prospeo help center, September 2026; Prospeo API docs). The public pages do not settle it, so test a free key before you plan around it. Starter is capped at 2,000 enrichment requests and 1,000 search requests a day (Prospeo pricing, September 2026). Bigger daily caps need Growth or Pro.

Volume means add-on maths

Credit add-ons start at 500 credits for $10 on monthly billing, and 1,000 credits cost $20, which is $0.02 a credit. The rate falls to $0.01 at 350,000 credits a month and $0.009 at 500,000 credits a year (Prospeo pricing, September 2026). One FAQ line on the pricing page says "from 1,000 credits for $10", which its own add-on table contradicts. Plans are priced per user. A team that wants millions of lookups ends up in a sales conversation.

Search is shallow and thin

One search returns 25 results a page, and a single search stops at 25,000 results. Search results carry no email or mobile, so you pay a second time to enrich them (Prospeo API docs, September 2026).

LeadOcean vs Prospeo

Prospeo figures come from prospeo.io and the sources linked in each cell, checked in September 2026. Prospeo changes plans and limits, so check the page before you buy.

What 1M, 5M and 25M records cost

Prospeo charges per verified email or mobile, so cost scales with volume. LeadOcean Pro stays at $499 a month. No single Prospeo tier reaches 1M credits, so the 1M figure is the cheapest public mix of seats and an add-on, and nothing public is priced above it.

Prospeo arithmetic for 1M emails on monthly billing: 44 Pro seats x $249 = $10,956 for 660,000 credits, plus the 350,000-credit add-on at $3,500. That is 1,010,000 credits for $14,456 a month (Prospeo pricing, September 2026). Add-on credits are shared by the team and do not grow with seats. The figure assumes every lookup finds a result. A mobile costs 10 credits, so 1M mobiles is 10M credits, and no public plan sells that.

If 1M is a one-off and not a monthly need, yearly billing is cheaper. Three Pro seats at $2,241 a year plus the 500,000-credit yearly add-on at $4,500 cost $11,223 once and deliver 1,040,000 credits upfront. Yearly seats cannot be mixed with a monthly add-on.

Prospeo publishes nothing above 350,000 add-on credits a month ($3,500, $0.01 a credit) or 500,000 a year ($4,500, $0.009). The help center says the standard list goes to 350,000 credits a month or 3.5M a year, and that support enables extended pricing on request (Prospeo help center, September 2026). A quote above 1M will differ, so ask for one.

Credits do not roll over. Unused plan and add-on credits expire at the end of each billing cycle, monthly or yearly (Prospeo help center, September 2026). The pricing page has an A/B variant that says credits roll over, but the help center is the policy.

Where LeadOcean wins

A flat bill at any volume

Pro is $499 a month. Every person or company returned counts as a record, but there is no credit balance to watch, no seat count and no overage invoice. A very large month is paced down to one request a minute until the reset, not cut off. One email to support gets you more headroom.

Phones and emails cost the same lookup

Prospeo prices a mobile at ten times an email. LeadOcean counts one record whichever field you want. POST /v1/people/enrich with reveal_email returns every email and phone number we hold for one record, and GET /v2/people/phone is a one-record phone lookup.

Built for code and agents

Both tools have REST and MCP. The difference is the gate. LeadOcean's Free plan includes the API and the 12-tool MCP server, so you test the real thing before paying. Count an audience for nothing, then enrich one person.

curl "https://api.leadocean.io/v1/people/search?jobLevel=Director&country=US&limit=1&count=true" \
  -H "x-api-key: $LEADOCEAN_API_KEY"

curl -X POST "https://api.leadocean.io/v1/people/enrich" \
  -H "x-api-key: $LEADOCEAN_API_KEY" \
  -H "content-type: application/json" \
  -d '{"linkedin_url":"https://www.linkedin.com/in/jane-doe","reveal_email":true}'

For Claude or Cursor, add the MCP URL https://api.leadocean.io/mcp and sign in with OAuth. No key gets pasted into a chat. count_leads, list_filters and get_account cost nothing.

Search and export at database scale

LeadOcean holds 693M people and 63M companies in one database. Search people with 50 filters and companies with 34, across 254 countries and 534 industries. Export up to 50,000 rows per request with POST /v1/exports, so a 1M-row pull is 20 calls over two days.

Where Prospeo wins

Cheaper at low volume

Below roughly 30,000 emails a month on monthly billing, Prospeo costs less. Add-ons start at $20 for 1,000 credits ($0.02 a credit), and 35,000 credits cost $525 ($0.015), so $499 buys about 33,000 add-on credits (Prospeo pricing, September 2026). Two Pro seats cost $498 for 30,000 credits. Yearly billing is 25% cheaper on Prospeo, which moves the crossover up. A solo founder on Starter pays $49 for 2,000 credits. Flat $499 only pays off when you use it.

An app for reps

Prospeo has a Chrome extension on every plan, CSV enrichment, HubSpot and Salesforce sync, job change tracking and intent topics (Prospeo pricing, September 2026). LeadOcean has none of these. It is an API, an MCP server and CSV export. A sales team that lives in a browser should stay in Prospeo.

Verified emails and a freshness claim

Prospeo returns verified emails and charges only for those. Its homepage claims 98% data accuracy and weekly refreshed data (Prospeo, September 2026). LeadOcean returns every status, from verified to spam_trap, and leaves the filtering to you. If you want a vendor-side guarantee on the address, Prospeo sells that. We have not tested either accuracy claim.

Use both: LeadOcean for volume, Prospeo for the final reveal

You do not have to pick one. Pull the audience from LeadOcean at a flat fee, then spend Prospeo credits only where they add something. A miss on Prospeo costs no credit, so the spend stays on hits.

1. Create a free LeadOcean key at app.leadocean.io/register. The free plan needs no card.
2. Count the audience for free, pull it with GET /v1/people/search or POST /v1/exports, and keep the verified rows. Load them into your sequencer.
3. For the rows that are catch_all or risky, or the people you will phone, call Prospeo's POST https://api.prospeo.io/enrich-person with only_verified_email or enrich_mobile. Credits go only to the hard cases.
