B2B Leads API: direct answer

A B2B leads API is useful when lead search, enrichment, or list generation needs to happen inside a product, CRM workflow, internal tool, or recurring data process. Dievio keeps API usage separate from dashboard subscription credits.

What must be clear before automation

Use these points to check whether the page maps to a real buying or data workflow, not just a broad category label.

Separate usage

API credits are handled separately from dashboard subscription credits, which keeps automated jobs easier to monitor.

Manual-to-API path

Teams can validate filters in the dashboard before turning the same search pattern into a recurring API workflow.

Structured output

API workflows are best when downstream systems know the required contact fields, dedupe rules, and result limits.

Who should use this page

Use these paths to decide whether Dievio fits the actual lead generation job, not just the broad software category.

Internal tools

Developers building internal lead search tools.

Agency systems

Agencies automating recurring list generation.

RevOps workflows

RevOps teams connecting B2B lead data to custom workflows.

Product use cases

Products that need structured contact data as part of a workflow.

How to plan an API workflow

Start with the exact system that will consume the data, then define filters, volume limits, retry behavior, dedupe rules, and the fields required downstream. API credits should be tied to returned records and monitored separately from dashboard exploration.

Define the segment

Lock the buyer role, company profile, geography, and data availability rules before export.

Preview before credits

Check whether the market is too narrow, too broad, or missing required contact fields.

Export by message

Split lists by persona or use case so outreach, enrichment, and reporting stay clean.

API implementation guardrails

Treat the API as a production data workflow with limits and monitoring, not just a button that exports more leads.

  • Define required fields and fallback behavior before writing the integration.
  • Set caps per company, segment, or customer so automated usage stays predictable.
  • Log returned records, credit usage, dedupe decisions, and downstream sync status.
Workflow proof

B2B Leads API implementation test

A useful API page should make the integration job concrete: inputs, required fields, usage caps, and downstream ownership.

Input contract

Define role filters, company filters, geography, required contact fields, result limits, and segment names.

Keeps automated searches specific enough to monitor.
Output contract

Map returned contacts into CRM, product, scoring, routing, enrichment, or client delivery fields.

Reduces manual cleanup after records are returned.
Usage control

Track API credits, returned records, misses, dedupe decisions, and sync failures separately.

Makes repeatable lead workflows safer to run.
Implementation

Example API planning note

Define this before writing code so the API workflow has a clear boundary.

{
  "segment": "b2b-leads-api",
  "requiredFields": ["email", "linkedinUrl", "companyDomain"],
  "maxResults": 100,
  "dedupe": true
}
Owner
RevOps, product engineering, or agency delivery
Stop condition
Pause when match rate, credit use, or sync errors move outside expected limits

How to decide before you spend time or credits

Use this section as a practical checklist before building the list, comparing vendors, or moving the workflow into API usage.

Use dashboard first

Validate filters manually before turning a lead search into recurring API calls.

Move repeatable jobs to API

Automate searches that run on a schedule, feed an internal tool, enrich records, or create lists for multiple teams.

Control usage separately

Keep API credits, dashboard credits, rate limits, dedupe rules, and downstream storage clearly separated.

Recommended workflow

1

Define search inputs

Use filters such as role, seniority, location, company size, industry, domain, email status, and phone status.

2

Run API searches with credit control

API credits are separate from dashboard subscription credits, which keeps automated usage easier to monitor.

3

Route results into your system

Use returned lead data for enrichment, scoring, routing, prospect list creation, or outbound workflow handoffs.

Example searches to run in Dievio

These are starter patterns, not fixed templates. Use them to test coverage, then adjust one filter group at a time.

CRM enrichment job

Filters
Company domains from CRM; target seniority; email availability; capped results per company.
Use it for
Fill missing buyer contacts in accounts already owned by the team.
Export fields
Structured records for CRM update, dedupe, and scoring.

Recurring agency list builder

Filters
Stored ICP template per client; location and industry variables; verified email required.
Use it for
Automate weekly or monthly lead list delivery while monitoring API credits.
Export fields
JSON records converted into client CSV files or internal dashboards.

Product-led lead lookup

Filters
User-selected role, company type, geography, and data availability from an app workflow.
Use it for
Let users generate targeted contacts without leaving your product.
Export fields
API response with contact fields, company context, and usage tracking.

Filters to start with

These are the first filter groups to test. Start with the strict version, preview the count, then loosen one dimension at a time so relevance does not collapse.

People filters

Title, seniority, department, location

Company filters

Industry, employee size, revenue, domain

Data filters

Email status, phone status, LinkedIn URL

What the API workflow should be ready for

The workflow should return structured records that can be deduped, routed, monitored, and used by the destination system without manual cleanup.

  • Defined request filters, result limits, and required contact fields.
  • Separate tracking for API credit usage, returned records, dedupe rules, and failed downstream syncs.
  • A tested manual segment before the same search becomes recurring automation.

Use the dashboard for exploration, API for repeatability

Teams can test segments manually in the dashboard, then move repeatable workflows into API calls once the filters and output requirements are clear.

Keep API usage separate from subscription credits

Dievio API credit top-ups are separate from dashboard subscription credits. That separation helps teams control automated usage and forecast cost.

Validate the segment before you export

Use Dievio preview counts to check market size, tighten filters, and export leads only when the list is ready for outreach.
