The BlitzAPI alternative with emails, phones and MCP in one plan

BlitzAPI is a B2B data API sold on flat monthly plans, so the price model is not why you would leave. The reasons are data type, phone coverage and MCP. LeadOcean is one $499 plan with emails and phones included, plus an MCP server that returns records.

Why teams switch from BlitzAPI

Emails and phones are plan upgrades

BlitzAPI Core costs $399 a month and leaves out emails and phones. Verified emails start on Plus at $499, and US phone numbers need Full at $599 (BlitzAPI pricing, September 2026). If you enrich for contact data, the $399 plan is not the one you buy.

The fast rate limit has a deadline

BlitzAPI lists 50 requests per second on every plan, against a standard 5. The page ties that to accounts opened by September 30 (BlitzAPI pricing, September 2026). The limit also applies per endpoint (BlitzAPI docs, September 2026).

Its MCP server reads docs, not data

BlitzAPI's MCP server gives an AI tool access to the API documentation. You still call the data API yourself (BlitzAPI docs, September 2026). An agent cannot search people or enrich a lead through it.

Phones stop at the US border

BlitzAPI holds 45M+ phone numbers, and its docs say phone enrichment is US-only (BlitzAPI docs, September 2026). If you call outside the US, that plan tier does not cover you.

LeadOcean vs BlitzAPI

BlitzAPI figures come from blitz-api.ai and docs.blitz-api.ai, checked in September 2026. Plan terms change, so check the pricing page before you buy.

What 1M, 5M and 25M records cost

BlitzAPI and LeadOcean are both flat, so volume does not change either bill until a fair-use line. The BlitzAPI column depends on which data you need. Emails need Plus at $499. Emails and US phones need Full at $599.

BlitzAPI arithmetic: paid plans have no credits, so the cost is the plan fee: $399, $499 or $599 (BlitzAPI pricing, September 2026).

Results and records may not map one to one. BlitzAPI counts results against its 15M limit, which applies to accounts opened by September 30, 2026, and its docs count one record per successful email lookup. At 1M and 5M you are well inside either way. Plan prices and limits for accounts opened later are not published.

Where LeadOcean wins

Emails and phones on the same price

Pro is $499 a month and covers every endpoint. You do not pick a data type when you pick a plan. LeadOcean holds 366M people with an email and 166M people with a phone number, all on the same plan.

An MCP server that returns data

The same data is reachable over REST and over MCP. An agent can count an audience for free, search it, enrich a lead and export rows without you writing glue. The Free plan includes both, so you can test the whole thing before paying.

Send one request and get a profile, email status and, with reveal_email, the emails and phone numbers we hold, for one record. The second call below is BlitzAPI's email lookup, for comparison.

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}'

curl -X POST "https://api.blitz-api.ai/v2/enrichment/email" \
  -H "x-api-key: $BLITZAPI_API_KEY" \
  -H "content-type: application/json" \
  -d '{"person_linkedin_url":"https://www.linkedin.com/in/jane-doe"}'

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.

A higher, simpler rate limit

Every key gets 100 requests per second on every plan, Free included. There is no per-endpoint budget to divide across workers and no deadline on the terms. That is 20 times the standard BlitzAPI rate.

Search and export at database scale

Search people with 50 filters and companies with 34, across 254 countries and 534 industries. Counts are free. Export up to 50,000 rows per request with POST /v1/exports, so a 1M-row pull is 20 calls over two days.

Where BlitzAPI wins

Job postings and hiring signals

BlitzAPI lists over 100 million job postings (BlitzAPI docs, September 2026). It has endpoints to search jobs, list a company's postings and find companies by the jobs they post (BlitzAPI docs). LeadOcean has no job-postings dataset. If your trigger is "they are hiring a data engineer", BlitzAPI has the data and we do not.

A cheaper way in without contact data

Core is $399 a month for company and people data without emails or phones. If you only need firmographics, LinkedIn profiles and job signals, that undercuts Pro by $100. You give up the contact data, which is the reason most teams buy an API.

Typed SDKs and waterfall search

BlitzAPI ships typed Python and TypeScript clients with retries, rate limiting and auto-pagination (BlitzAPI docs, September 2026). It also has a Waterfall ICP endpoint that cascades through decision-maker titles. LeadOcean is plain REST, MCP and CSV export, so you write the retry loop and the title cascade yourself.

Use both: BlitzAPI for signals, LeadOcean for contacts

You can keep BlitzAPI for job signals and use LeadOcean to find the people behind them. BlitzAPI Core at $399 covers the signal. LeadOcean's free plan, or Pro, covers the contact data.

1. Create a free LeadOcean key at app.leadocean.io/register. The free plan needs no card.
2. Use BlitzAPI's job search to find companies that are hiring for the role you sell against. Keep each company's domain.
3. Call GET /v1/companies/{domain}/people on LeadOcean for the people at each domain, then POST /v1/people/enrich with reveal_email on the ones you want.
