A B2B leads API for search, enrichment, and outbound workflows
Dievio API access lets teams build lead search and enrichment workflows with separate API credit top-ups, structured filters, and B2B contact data for custom systems.
API fit
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.
API credits are handled separately from dashboard subscription credits, which keeps automated jobs easier to monitor.
Teams can validate filters in the dashboard before turning the same search pattern into a recurring API workflow.
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.
B2B Leads API implementation test
A useful API page should make the integration job concrete: inputs, required fields, usage caps, and downstream ownership.
Define role filters, company filters, geography, required contact fields, result limits, and segment names.
Keeps automated searches specific enough to monitor.Map returned contacts into CRM, product, scoring, routing, enrichment, or client delivery fields.
Reduces manual cleanup after records are returned.Track API credits, returned records, misses, dedupe decisions, and sync failures separately.
Makes repeatable lead workflows safer to run.Example API planning note
Define this before writing code so the API workflow has a clear boundary.

}- 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
Define search inputs
Use filters such as role, seniority, location, company size, industry, domain, email status, and phone status.
Run API searches with credit control
API credits are separate from dashboard subscription credits, which keeps automated usage easier to monitor.
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.
