## Pricing

from $17.00 / 1,000 mobile founds

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## Mobile Phone Waterfall

### 📱 What can Mobile Phone Waterfall do?

Give it **contacts** and it finds a **mobile phone number** for each one by calling the phone
providers you already pay for, one after another, until one returns a number. Every row says which
provider found it, what line type it is, and how many of **your** credits it spent.

**Bring your own keys.** You supply your own Prospeo, Lusha, ContactOut, or FullEnrich key, any
one of them or all four. Mamba Labs supplies no keys and stores none. You pay your providers
directly at your own plan's rate.

| 📦 What you get | ⚙️ Features and integrations |
|---|---|
| 📞 **A mobile number in E.164 format**, or an honest null<br>🏷️ **Line type, country, and the Do Not Call flag** where the provider reports them<br>🧾 **Per provider credits** on every row<br>🔢 **25 fields**, one flat row per contact, always | 🔗 **Four providers in the order you set**<br>🔌 **A circuit breaker per provider** on a bad key or an empty balance<br>🛑 **Your own credit cap** and an Apify charge cap<br>⬇️ **Export** to JSON, CSV, Excel, HTML, or XML |

> 🚫 **This is not a data provider and sells you no phone data.** It runs the accounts you already
> have. With no key supplied it still runs, says which providers were unavailable, charges only the
> run start fee ($0.0005), and exits cleanly.

### 💡 Why use Mobile Phone Waterfall?

No single provider finds every mobile. Running two or three by hand means exporting, matching, and
paying twice for the same person. This calls the next provider only when the one before it came back
empty, so a found contact never spends credits on a second provider.

| If you want | Read these fields |
|---|---|
| The number | `mobile_phone`, `phone_line_type`, `phone_country` |
| Whether you may dial it | `phone_dnc` (Lusha reports it; null means not reported) |
| Which provider earned its keep | `found_by_provider`, `found_by`, `chain_position` |
| What the contact cost you at your providers | `provider_credits_used`, `providers_attempted_json` |
| Run totals | `run_summary_json` on the summary row |

### 🔌 Supported providers

| Provider | Your key field | Identifiers it takes | Credits per mobile, as documented |
|---|---|---|---|
| Prospeo | `prospeo_api_key` | LinkedIn URL, name plus domain, email, name plus company | 10 per mobile found, a miss is free |
| Lusha | `lusha_api_key` | LinkedIn URL, email, first and last name plus domain or company | one search charge plus a phone charge per revealed phone |
| ContactOut | `contactout_api_key` | LinkedIn profile URL (`/in/` or `/pub/`) only | one phone credit when a phone comes back |
| FullEnrich | `fullenrich_api_key` | first and last name plus company domain, LinkedIn URL optional | 10 per mobile found, landlines free |

The default order is Prospeo, Lusha, ContactOut, FullEnrich. FullEnrich runs last because it is
itself a waterfall over 20 plus sources and takes up to two and a half minutes per contact. Change
the order with `provider_order`. A provider with no key is skipped and reported, never an error.

**Live verification.** The Prospeo path has been run live on a real key (2026-10-19). The Lusha,
ContactOut, and FullEnrich steps are built to each provider's documented API but have not yet been
run on a live key. Every run summary lists them under `providers_not_live_verified`.

**A LinkedIn URL is passed to the provider as an identifier. The actor never opens LinkedIn.**

### 📋 What data can Mobile Phone Waterfall extract?

**25 fields** per row. One row per input contact, always, including the ones where nothing was
found, plus one run summary row.

| Field | What it holds |
|---|---|
| `contact_id` | Your own `id` or `contact_id`, echoed back, or a row id |
| `input_full_name`, `input_first_name`, `input_last_name` | The name you supplied |
| `input_company_domain`, `input_company_name` | The company you supplied |
| `input_linkedin_url`, `input_email` | The identifiers you supplied |
| `mobile_phone` | The number in E.164, for example `+14155550123`, or null |
| `phone_line_type` | `mobile`, `landline`, `voip`, or `unknown` |
| `phone_country` | Two letter country code of the number |
| `phone_dnc` | True when the provider flags the number Do Not Call |
| `phone_status` | `found`, `not_found`, `no_usable_identifier`, `no_provider_available`, `skipped_spend_cap`, `skipped_free_plan_cap`, `not_started_charge_limit`, or a summary state |
| `found_by_provider`, `found_by` | The provider, and the exact registry entry, that answered |
| `chain_position` | Which position in your order found it |
| `providers_called` | How many providers were actually called for this contact |
| `providers_attempted_json` | Every provider step with its outcome, credits, and time |
| `provider_credits_used` | Credits this contact spent on your accounts |
| `is_summary_row`, `run_summary_json` | The run summary row and its totals |
| `row_status`, `error_reason` | `ok`, `no_match`, `skipped`, `error`, or `summary`, and why |
| `billable_events_json` | The Apify events this row charged, `[]` when free |
| `checked_at` | When the row was written |

### ⬇️ Input

| Field | What it does |
|---|---|
| `contacts` | One object per person: `full_name`, `first_name`, `last_name`, `company_domain`, `company_name`, `linkedin_url`, `email`, and your own `id`. Also accepted as a JSON string or one line per person. |
| `full_name`, `company_domain`, `linkedin_url`, `email` | One person per run, the shape a Clay row sends |
| `prospeo_api_key`, `lusha_api_key`, `contactout_api_key`, `fullenrich_api_key` | Your keys. Secret fields: never logged, stored, or written to the dataset |
| `provider_order` | Provider names in call order. Empty means the default order |
| `mobile_only` | On by default: a landline or VoIP number does not end the chain. Numbers without a reported line type are kept as `unknown` |
| `max_contacts` | Ceiling on contacts processed |
| `max_provider_credits` | Your spend cap on provider credits. Remaining contacts are skipped, uncharged |
| `max_charge_usd` | Your cap on this run's Apify charges |

Example:

```json
{
  "contacts": [
    { "id": "crm-1042", "full_name": "Jane Doe", "company_domain": "example.com", "linkedin_url": "https://www.linkedin.com/in/janedoe" }
  ],
  "prospeo_api_key": "YOUR_PROSPEO_KEY",
  "lusha_api_key": "YOUR_LUSHA_KEY",
  "max_provider_credits": 200
}
```

### 💰 Pricing

Pay per event. You pay Apify for the orchestration below, and you pay your providers separately on
your own keys.

| Event | When it fires | Free | Bronze | Silver | Gold |
|---|---|---|---|---|---|
| `apify-actor-start` | Once per run | $0.0005 | $0.0005 | $0.0005 | $0.0005 |
| `phone-search-submitted` | Once per contact on which at least one provider was called | $0.003 ($3.00 per 1,000) | $0.00285 | $0.0027 | $0.00255 |
| `mobile-found` | Once per contact that comes back with a number | $0.020 ($20.00 per 1,000) | $0.019 | $0.018 | $0.017 |

A contact that reached no provider (no key, no identifier a provider accepts, your credit cap, the
free plan cap) is free. Summary rows are free. The run stops at the maximum cost per run you set in
Apify and at `max_charge_usd`, and keeps every row already paid for.

**Free plan:** up to 65 contacts per calendar month on the Apify Free plan, which is 1.50 USD of
evaluation at the Free prices. Paid plans have no monthly contact cap.

### 🧪 Usage examples

**Apify Console or API.** Paste your contacts and at least one key, then run. Over the API, start
`POST /v2/acts/<actor id>/runs` with the input above and read the dataset when the run finishes.

**Clay.** Add an HTTP API or Apify column, map `full_name`, `company_domain`, and `linkedin_url` to
the single contact fields, and pass your key in the matching key field. Clay sends every value as a
string; the actor accepts that.

**MCP.** The Mamba Labs MCP server `@mambalabsdev/mcp-mobile-phone-waterfall-orchestrator` exposes
this actor as the tool `find_mobile_phone` for Claude, Cursor, and other MCP clients.

### 🧯 Error handling

| Situation | What you get |
|---|---|
| No key at all | One summary row, `phone_status` `no_run`, nothing called, only the run start fee charged, exit 0 |
| A bad key or an empty balance | That provider is switched off for the rest of the run after one failed call; the chain continues |
| Rate limit | Calls are paced to each provider's documented limits; a 429 is not retried into a second 429 |
| A provider times out | That step is recorded as an error and the chain moves on |
| FullEnrich still working after 150 seconds | Recorded as an error. FullEnrich may still finish and charge your account later |
| A masked or national format number with no country | Not counted as found |

### ⚠️ Limitations

- Match rates are not stated here because they have not been measured on a shared contact set. They
  vary by provider, country, and seniority.
- Only Lusha reports a Do Not Call flag. A null `phone_dnc` means not reported, not cleared. Calling
  and texting rules (TCPA, national Do Not Call registers, GDPR) are yours to follow.
- ContactOut reports no line type, so its numbers read `unknown` and pass the `mobile_only` filter.
- Each provider's own terms bind your account. Lusha and Kaspr forbid reselling their data; Kaspr is
  not supported. Apollo is not supported because it delivers phone numbers only to a webhook.
- Credits are reported as each provider reports or documents them. Dollar cost depends on your plan.

### 🆘 Support

Open an issue on the **Issues** tab with the run id. Want another provider added? Say which one.

# Actor input Schema

## `contacts` (type: `array`):

One object per person with any of: full_name, first_name, last_name, company_domain, company_name, linkedin_url, email, and your own id or contact_id. A LinkedIn URL is the strongest identifier for most providers and is only passed to them, never opened. Also accepted as a JSON string, or one line per person, because Clay sends every input as a string.

## `full_name` (type: `string`):

Optional. For one person per run, the shape a Clay row sends. Added to the contacts list.

## `company_domain` (type: `string`):

Optional, with full_name for a single contact.

## `linkedin_url` (type: `string`):

Optional, for a single contact. Passed to providers as an identifier, never opened by the actor.

## `email` (type: `string`):

Optional, for a single contact.

## `prospeo_api_key` (type: `string`):

Your Prospeo key. Prospeo charges 10 credits per mobile found and nothing on a miss.

## `lusha_api_key` (type: `string`):

Your Lusha key (V3 API). Lusha charges a search credit plus a phone credit per revealed phone.

## `contactout_api_key` (type: `string`):

Your ContactOut API token. LinkedIn URL lookups only; a phone credit is spent only when a phone comes back.

## `fullenrich_api_key` (type: `string`):

Your FullEnrich key. FullEnrich is itself a waterfall over 20 plus sources and charges 10 credits per mobile found; it runs last by default.

## `provider_order` (type: `array`):

Optional. Provider names in the order to call them: prospeo, lusha, contactout, fullenrich. Leave empty for that default order. A provider with no key is skipped and reported.

## `mobile_only` (type: `boolean`):

On by default: a landline or VoIP number does not count as found, and the chain moves on to the next provider. Numbers a provider returns without a line type are kept and labeled unknown.

## `max_contacts` (type: `integer`):

Optional ceiling on how many contacts this run processes.

## `max_provider_credits` (type: `integer`):

Cap on the provider credits this run may spend from YOUR accounts. When it is reached, the remaining contacts are skipped with a reason and not charged. Strongly recommended.

## `max_charge_usd` (type: `number`):

Optional. The run stops before any Apify charge that would take this run past this amount, and keeps every row already paid for. The run also honors the maximum cost per run set in Apify.

## `source_tag` (type: `string`):

Internal attribution tag set by Mamba Labs on published task examples. Leave it empty.

## Actor input object example

```json
{
  "contacts": [
    {
      "contact_id": "example-1",
      "full_name": "Jane Doe",

    }
  ],
  "provider_order": [],
  "mobile_only": true,
  "max_provider_credits": 200

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
