LinkupAPI Review 2026: LinkedIn Automation API Tested

LinkupAPI is a Paris-based API that connects AI agents and B2B software to LinkedIn, WhatsApp, and public web data through one credit-based interface. Plans start at $29 a month for 500 credits, a LinkedIn action costs about one credit, and an MCP server ships on every tier. That makes it the cheapest published entry point into LinkedIn infrastructure we have reviewed, and also the youngest product in the category, with the gaps that youth implies.

This LinkupAPI review covers what the API actually does, its verified 2026 pricing and credit math, the safety model, the places where the documentation contradicts the marketing, and when a managed platform makes more sense than raw endpoints. Every claim was checked against LinkupAPI’s own site, pricing page, docs and terms in August 2026, the same way we reviewed Unipile and the rest of the LinkedIn infrastructure field.

What is LinkupAPI, and which Linkup is this?

Three unrelated products share this name, and most search results confuse them. Linkup at linkup.so is an AI web search API used for retrieval pipelines. LinkUp at linkup.com sells job market data. LinkupAPI at linkupapi.com, the subject of this review, is a LinkedIn and WhatsApp automation API for developers, operated by LINKUPAPI SAS in Paris. Its terms of use are dated February 2025, which makes it one of the youngest vendors in the category. Check the domain before you compare pricing or reviews, because directories regularly mix the three up.

The pitch is one API between your software and B2B channels. Three products sit behind roughly 50 endpoints: an Engagement API for LinkedIn actions (messages, invitations, comments, likes, posts and searches, plus WhatsApp messaging), a Web Crawler API for public company data, and a Mail API for finding and verifying professional email addresses. Version 2 is action-based, one endpoint per category with an action field selecting the operation. An unusual extra is a set of recruiter endpoints for job postings and candidate CVs, which its direct competitors do not expose.

Accounts are the customer’s own, connected either with the account’s email and password or by passing a session token directly. There is no hosted authentication widget, so collecting and transmitting those credentials is your application’s problem. Each connected account gets a proxy in one of eleven selectable countries, France by default, and a dedicated checkpoint endpoint handles two-factor codes and in-app validations when LinkedIn challenges a login.

How much does LinkupAPI cost in 2026?

Pricing is a monthly subscription with included credits, in dollars, verified on the LinkupAPI pricing page in August 2026. There is no annual option, no free tier and no published trial, and refunds stop the moment a single credit is spent.

The credit grammar decides what those numbers mean. Most actions cost one credit per request, a message with media costs two, and list endpoints such as search or connections charge one credit per ten results, rounded up. Even connecting an account or solving a checkpoint costs a credit. So the $29 tier covers roughly 500 sent actions a month, and at LinkupAPI’s own recommended pace of 80 to 100 invitations a day, a single active sender exhausts it in under a week. Real outreach volume starts at the $150 tier, and because credits price calls rather than connections, the model favors data-heavy workloads over sending-heavy ones, and many idle connected accounts cost nothing extra.

Two soft spots are worth knowing before you subscribe. The terms reference credit expiration rules described in the pricing documentation, but the pricing page describes none. And the support FAQ promises priority support on Premium and Enterprise plans, names that do not exist in the current tier list. Neither is disqualifying; both are the paperwork of a very young product.

Does LinkupAPI run campaigns, or just actions?

The homepage says you can launch outreach campaigns and sequences directly from your product. The documentation says otherwise: across the full v2 endpoint list there are no campaign, sequence or scheduling endpoints, only primitives. LinkupAPI’s own architecture guidance is more honest, telling you to process API calls through a queue with random delays between jobs. The sequencing engine, campaign state, reply handling and retry logic are yours to build. That is the same gap we documented for Unipile, and it is the most underestimated line item in the build-versus-buy decision for outreach products.

Is LinkupAPI safe for LinkedIn accounts?

LinkupAPI enforces no limits of its own. Its best practices page states plainly that nothing is limited on their side and your account hits the same ceilings as in the LinkedIn interface. What it publishes instead are recommendations: 80 to 100 invitations a day on a paid account, 30 to 50 messages, around 100 profile views, a two to three week warm-up on new accounts, and real accounts only. Those numbers are consistent with what the rest of the market publishes, but nothing stops your code from exceeding them, and the terms are blunt about where the risk lands: providers may restrict or suspend accounts at their discretion, and you remain responsible for actions as if you had performed them from the account yourself.

One compliance claim deserves scrutiny. The marketing FAQ describes a zero-storage architecture and says account credentials are never stored on LinkupAPI’s servers. The terms of use say the opposite: the service stores connected-account tokens and credentials, encrypted at rest, plus message data for as long as features require. Encrypted credential storage is a normal design for this category; advertising zero storage while documenting the storage is not. The same pattern touches reliability: the homepage advertises 99.9% uptime while the terms provide access on a best-effort basis with no SLA and no public status page. Read both pages and decide which one your compliance review believes.

What do users say about LinkupAPI?

Almost nothing on the record yet. We could not verify a G2 profile for LinkupAPI at the time of writing, no named customers or testimonials are published, and the homepage social proof is illustrative mockups rather than case studies. That is normal for a product whose terms are dated February 2025, but it means adopting it makes you an early customer, with the pricing leverage and the platform risk that both implies. If an account restriction costs you a client relationship, the terms cap the vendor’s liability at twelve months of fees.

Is there an alternative to LinkupAPI?

It depends on which half of the product you are buying. If you want raw LinkedIn primitives at the lowest published price, the closest competitor is Unipile, which prices per connected account (from 49 EUR a month) rather than per call and adds hosted authentication, email and calendar channels, SDK tooling and a longer track record. Our guide to Unipile alternatives compares the raw API field in detail.

If what you actually need is outreach that works from day one, the comparison changes category. Swarmhit is the managed layer: multi-sender campaigns with rotation, a unified inbox with assignment and interest tags, AI personalization drawn from each prospect’s profile, posts and company news, and managed account safety on every plan, with a dedicated proxy per sender, auto-warmup, health checks, smart caps and 100+ safeguards monitored 24/7. The same engine is exposed to your product or agents through the API, webhooks and an MCP server. Platform plans are $39 per sender per month, $29 on annual billing. Developer pricing is heavily discounted against the $39 platform rate and carries a minimum sender count, agreed on the integration call. It is graduated rather than flat: each band of senders is priced at its own rate, so adding senders lowers what the next ones cost rather than repricing the fleet you already have.

FAQ

Is LinkupAPI the same as Linkup?

No. LinkupAPI (linkupapi.com) is a LinkedIn and WhatsApp automation API for developers. Linkup (linkup.so) is an AI web search API for retrieval, and LinkUp (linkup.com) sells job market data. The three companies are unrelated, and search results and directories regularly mix them up, so verify the domain before trusting any pricing or review you find.

How much does LinkupAPI cost in 2026?

LinkupAPI costs $29 a month for 500 credits on Basic, $150 for 5,000 on Pro, $800 for 50,000 on the Porsche tier, and $3,000 for unlimited usage on Company. A LinkedIn action costs about one credit, media messages cost two, and list endpoints charge one credit per ten results. No annual billing or free trial is published.

Is LinkupAPI safe for LinkedIn accounts?

LinkupAPI ships proxies, checkpoint handling and conservative recommendations, but it enforces no limits of its own and its terms place restriction risk entirely on you. Outcomes depend on the pacing and warm-up behavior your code implements. Our LinkedIn automation safety guide covers the behavioral rules that actually decide account health.

Does LinkupAPI have an MCP server?

Yes. An MCP server is included on every tier at mcp.linkupapi.com, authenticated with OAuth 2.1 or an API key, with setup guides for Claude, ChatGPT, Cursor, Gemini and other clients. An AI agent can drive LinkedIn actions through it directly, though it works with primitives rather than campaigns, so durable outreach state still needs to live somewhere else.

Does LinkupAPI run outreach campaigns?

No. The documentation exposes no campaign, sequence or scheduling endpoints, and LinkupAPI’s own guidance tells you to build a queue with random delays. You write the sequencing logic, reply stops and retries yourself, or use a managed engine such as Swarmhit that ships them behind an API.

What is the best LinkupAPI alternative?

Unipile is the closest raw-API alternative, priced per connected account with hosted authentication and more channels. For teams that want a working outreach engine with programmatic access through API, webhooks and MCP, Swarmhit is the managed alternative. Our Unipile alternatives guide compares the whole field with verified pricing.

Conclusion

LinkupAPI earns a place in the 2026 LinkedIn infrastructure field on price alone: no published entry point is cheaper, the MCP server is genuinely useful for agent builders, and the credit model is friendly to fleets of mostly idle accounts. The reservations are equally real: it is a very young product whose marketing runs ahead of its documentation on campaigns, storage and uptime, and everything above the primitives is still your engineering. Builders comparing the raw APIs should read our Unipile review and the wider outreach API roundup next; teams that want the outcome rather than the plumbing can skip the assembly entirely.
