Enrich CRM records, prospect lists, and inbound leads through one API. Pintel.ai’s Waterfall Enrichment API queries 30+ B2B data providers in cascade order and returns the highest-confidence contact and company data available for every field — 95%+ verified match rates globally, including EMEA, APAC, and LATAM.
What Is a Waterfall Enrichment API?
A waterfall enrichment API queries multiple B2B data providers in sequence, starting with the highest-accuracy source for each field and cascading to broader fallbacks until a verified match is returned. The result is one clean, enriched record per request — not one record per provider.
Standard enrichment queries a single vendor database and returns whatever that provider has, often leaving gaps where coverage is weak. Waterfall enrichment eliminates most of those gaps without adding manual steps or multiple vendor integrations.
Why Single-Source Enrichment Leaves Gaps
Every enrichment vendor has coverage blind spots. When your pipeline depends on one source, those gaps become bad data in your CRM.
60–80% fill rates at best
Single-vendor enrichment averages 60 to 80% fill rates on a global ICP. The remaining 20 to 40% of records come back empty or partially enriched, creating manual work and data debt.
Cached data ages faster than it is refreshed
B2B contact data decays at roughly 37% annually. Most enrichment vendors serve data from a snapshot database refreshed on a schedule, not in real time. By the time a record reaches an SDR queue, the contact may have already changed roles.
Regional coverage collapses outside North America
Most enrichment tools are optimized for the US market. EMEA, APAC, and LATAM coverage degrades significantly with a single provider. The same ICP that returns a 75% fill rate in North America may return far fewer verified records in Germany, Japan, or Brazil.
Managing multiple vendor contracts is not scalable
Solving the gap problem by subscribing to multiple data providers forces RevOps to manage separate contracts, APIs, and data formats. The overhead negates much of the benefit. The fix is a single API that orchestrates multiple providers in priority order and returns one clean, verified result per field.
How Pintel.ai’s Waterfall Enrichment API Works
Each enrichment request triggers a provider cascade, not a single lookup. The API works down the cascade until it finds a match that meets the confidence threshold for each field.
Step 1: Send an enrichment request with any available identifier
Submit a record using any identifier you have — email address, LinkedIn URL, full name plus company domain, or company name alone. The API accepts partial data and resolves the best match available.
Step 2: Query the highest-accuracy provider first
For each field being enriched, the API selects the data source with the highest documented accuracy for that field type and geography. Work email and direct dial are queried against different priority providers. Provider priority is dynamic and geography-aware.
Step 3: Score the returned match against a confidence threshold
Every field returned from a provider is scored for match confidence. If the score is above the acceptance threshold, the field is accepted and the cascade for that field stops. If the score falls below the threshold, the API moves to the next provider.
Step 4: Cascade to the next provider if the match falls short
For any field that did not pass the confidence check, the API queries the next provider in the ranked list. This continues down the provider chain until a verified match is found or all providers for that field are exhausted.
Step 5: Return a single enriched record with per-field confidence scores
The API returns one clean record per input. Each field includes a confidence score so downstream systems, CRMs, or lead-scoring models can apply their own acceptance thresholds without additional logic.
What the Waterfall Enrichment API Returns
Every enrichment request returns verified contact and company data, ready to load directly into your CRM, sequencing tool, or data warehouse.
Verified work email with deliverability check
Every returned email address goes through deliverability validation including MX record lookup and catch-all detection, so you know whether an email is likely to reach the inbox before you send.
Direct dial and mobile phone validation
Phone numbers are validated for format and classified by line type (mobile vs. landline vs. VoIP). Direct dial numbers are prioritised over switchboard numbers so SDRs reach people, not gatekeepers.
Company data and firmographic enrichment
Company name, website, industry, headcount, revenue range, technologies used, and funding status are returned alongside contact-level data in a single API response.
Field-level enrichment with confidence scoring
Each field is returned with a confidence score (0 to 1). Downstream systems can apply custom thresholds — accept only contacts with email confidence above 0.9, or phone confidence above 0.8, for example.
Real-time and batch enrichment
Pintel.ai supports single-record real-time enrichment for use cases like PLG signup qualification and form submission routing, as well as batch endpoints that handle thousands of records asynchronously with webhook callbacks on completion.
How Teams Use the Pintel.ai Waterfall Enrichment API
CRM hygiene: re-enrich stale records at scale
Send existing CRM records through the batch API endpoint. The waterfall checks each record against 30+ providers and returns updated emails, direct dials, and job titles. On average, 37% of records come back changed each year.
Outbound prospecting: enrich lists before sequencing
Upload a target account and contact list. The API returns verified contact details per record before the list enters a sequencing tool. SDRs start with data that has already been verified, not data that needs to be manually checked.
PLG signup routing: qualify inbound leads in real time
On new product signups, pass the email address to the real-time enrichment endpoint. Convert personal-email signups to professional equivalents, score the account using firmographic and signal data, and route qualified accounts to the SDR queue automatically.
Lead scoring: enrich form submissions with complete data
Form submissions often capture only name and email. The enrichment API fills in job title, seniority, company size, and industry so your lead-scoring model has complete data to work with rather than blanks that default to the lowest tier.
Signal-based selling: enrich accounts showing buying signals
When an account triggers a buying signal — funding round, leadership change, tech migration — enrich the decision-maker list in real time. Outreach reaches the right person while the signal is fresh.
Event intelligence: enrich attendee lists before follow-up
Upload post-event attendee lists for batch enrichment. Receive verified contact details and ICP fit scores within hours. Segment follow-up by fit tier before anyone sends a single email.

Build vs Buy: Waterfall Enrichment In-House vs Pintel.ai API
Many engineering teams attempt to build waterfall enrichment in-house by chaining vendor contracts. Here is what that comparison looks like in practice.
| Consideration | Build in-house | Pintel.ai Waterfall Enrichment API |
|---|---|---|
| Time to first enriched record | Weeks to months — negotiate contracts, integrate multiple APIs, build and maintain cascade logic | Hours for most teams — single REST endpoint, one API key, standard JSON responses |
| Provider relationships | Negotiate separately with each vendor. A global ICP typically requires 3 or more separate contracts | One agreement. 30+ providers managed by Pintel.ai, including providers not available via self-serve |
| Provider accuracy ranking | Manual benchmarking required per field type and geography. Becomes stale as provider quality shifts | Accuracy ranking updated continuously based on live match data across all customers |
| Global coverage | Varies by which vendors you sign. EMEA and APAC coverage typically requires additional contracts | Geography-aware provider selection included. No additional contracts for international coverage |
| Ongoing maintenance | Provider API changes, rate limits, credential rotation, and accuracy drift require dedicated engineering time | Fully managed. Provider integrations, accuracy monitoring, and cascade logic maintained by Pintel.ai |
| Compliance | GDPR, CCPA, and data residency obligations must be assessed and managed per provider contract | ISO 27001 certified, SOC 2 (AICPA), GDPR, HIPAA, CCPA compliant, and VAPT certified |
