Cascade through verified data sources to find the best deliverable email and direct dial mobile number for a contact. Pay only for successful matches. Email and Mobile Phone Waterfall API solves the last-mile problem in outbound: you have a name and a company, but no contact info, or you have an email that bounces and need a working alternative. The waterfall cascades through multiple verified data sources, returns the best deliverable contact information, and only charges you when a match is found. Two endpoints: /waterfall/email cascades through verified work email sources, personal email sources, and pattern-derived emails with SMTP verification. Returns the best deliverable email with confidence score. 3 credits per successful match. /waterfall/phone cascades through verified direct dial mobile sources, work mobile sources, and operator data. Returns the best direct dial number with confidence score. 32 credits per successful match (mobile data is premium). Use cases: SDR and BDR outbound enrichment before launching a sequence Recruiting outreach when LinkedIn InMail is too slow or expensive Account executive outbound on tier-1 accounts where mobile reach matters Renewal and expansion outreach on dormant accounts Field marketing and event follow-up Comparable to LeadIQ, Cognism Diamonds, Lusha, RocketReach, and Apollo for waterfall services. Springbolt X advantage: integrated with keyword intent (verify the contact is in-market before paying for the direct dial). US-focused. TCPA aware. MCP-compatible.

ZoomInfo and Apollo alternative with keyword intent built in. Verified US B2B contacts with firmographics, technographics, and hashed-email exports. Springbolt X B2B List Building API builds fresh, verified US B2B contact lists from filter criteria: industry, headcount, revenue band, geography, technographic, job title, and seniority. Each record contains name, title, company, domain, verified deliverable email, direct dial phone, SHA-256 hashed email for ad platform upload, and full firmographic context. Comparable to ZoomInfo, Apollo, Lusha, and Cognism for list building, with two differences: Keyword intent is built into the same API. Filter your list build by the keywords your prospects have been searching. ZoomInfo and Apollo do not offer keyword-level intent. Every record exports with hem_sha256 ready for direct upload to Google Ads Customer Match, Meta Custom Audiences, LinkedIn Matched Audiences, YouTube TrueView, Taboola, and any programmatic DSP. Pricing scales from $0.866 per record at Starter tier down to $0.666 at Enterprise volume. Pay only for records returned.

Each response returns name, title, company, domain, industry, revenue band, headcount band, verified deliverable email, direct dial phone, and SHA-256 hashed email pre-formatted for upload to Google Ads Customer Match, Meta Custom Audiences, LinkedIn Matched Audiences, YouTube TrueView, Taboola, Outbrain, TikTok, Reddit, X, Snap, Pinterest, The Trade Desk, DV360, and any DSP that accepts hashed email.

Hashed Email API for Google Ads Customer Match, Meta, and LinkedIn Get SHA-256 hashed emails ready for direct upload to Google Ads Customer Match, Meta Custom Audiences, LinkedIn Matched Audiences, YouTube, and Taboola. Long Description: This API solves the problem every paid media team runs into: you have intent data, but your customer list is too small to build effective Custom Audiences on Google Ads, Meta, and LinkedIn. Springbolt X lets you build a Custom Audience from search intent instead of from your own customer file. Input a keyword or seed criteria. Output a CSV with the hem_sha256 column pre-formatted to every major ad platform's specification (lowercased, trimmed, SHA-256 hashed). Upload directly into: Google Ads Customer Match (Search, Display, Gmail, YouTube TrueView, Demand Gen, Performance Max) Meta Custom Audiences (Facebook feed, Instagram feed, Stories, Reels, Audience Network) LinkedIn Matched Audiences (Sponsored Content, Sponsored Messaging, Conversation Ads, Text Ads) Taboola Audience Targeting and Outbrain Custom Audiences for native ads on Yahoo, MSN, CNN, USA Today TikTok Custom Audiences, Reddit Custom Audiences, X Tailored Audiences, Snap Audience Match, Pinterest Audiences Programmatic DSPs: The Trade Desk, DV360, StackAdapt, Basis Typical match rates against Springbolt X audiences: 40-65% on Google Ads, 50-70% on LinkedIn (because our identity graph is purpose-built for verified B2B contacts). Minimum audience size: 100 matched users for Google Ads Demand Gen, 1,000 for Search.

LinkedIn URL to Email and Phone API converts LinkedIn profile URLs into verified contact information. Send the profile URL, get back the verified work email, direct dial mobile phone number, current job title, current company, and hashed email pre-formatted for Google Ads Customer Match and Meta Custom Audiences. Built for the sales rep who has a list of LinkedIn URLs from Sales Navigator, the recruiter sourcing from LinkedIn profile searches, the ABM team building a target contact list, and the growth marketer wanting to retarget LinkedIn profile visitors with Google Ads. Two resolution modes: /resolve/linkedin returns the verified email and direct dial phone for outreach /resolve/linkedin-hem returns only the SHA-256 hashed email for ad platform activation (useful when you need to build a Custom Audience without exposing PII) Comparable to Apollo, Lusha, RocketReach, Cognism, ContactOut, and Wiza, with broader coverage of US B2B contacts and direct dial mobile numbers verified through Springbolt's email and phone waterfall. Sub-second response. US-focused. TCPA, GDPR, CCPA aware. MCP-compatible for AI agent workflows in tools like Claude, ChatGPT, Cursor, and OpenAI Agents SDK.

Find verified contacts who searched a specific keyword on Google. Bombora and 6sense alternative with keyword-level precision, not topic buckets. Springbolt X Keyword Intent API gives you the verified email of the person who searched your competitor's name, your category, or your exact use case on Google, Bing, or a publisher search box last week. Not a "company is in-market" guess. The literal keyword and the verified contact who typed it. Other intent providers like Bombora, 6sense, Demandbase, and Anteriad sell topic-bucket intent ("CRM software intent," "sales automation surge"). Springbolt X sells the literal search query and the SHA-256 hashed email ready for upload to Google Ads Customer Match, Meta Custom Audiences, LinkedIn Matched Audiences, YouTube TrueView, Taboola, and Outbrain. How it works: the Springbolt Ad Network observes search queries across our publisher integrations. The Springbolt X identity layer resolves each signal to a verified contact record. You call the API with a keyword and get back name, title, company, firmographics, verified email, direct dial phone, and hem_sha256 pre-formatted to ad platform spec. Reverse lookup included: input a contact and see the exact keywords they have been searching. Useful for ABM prioritization. US-focused. TCPA, GDPR, CCPA aware. MCP-compatible for AI agent workflows.

Input a contact, see the exact keywords they have been searching. Reverse-direction intent data for ABM prioritization, expansion, and churn prediction. Most intent APIs work in one direction: input a keyword, get a list of accounts. Springbolt X Reverse Intent Lookup works the other way. Input a contact (email, LinkedIn URL, or hashed email) and get back the exact keywords that contact has been searching across Google, Bing, and publisher search boxes in the last 90 days. Use cases: ABM prioritization: which of your target accounts is actively searching for your category right now? Expansion targeting: which of your existing customers is searching for competitor names? (signal for churn risk) Account scoring: weight keyword recency and signal strength against your scoring model Sales talking points: the rep knows what the prospect has been researching before the first call Marketing message testing: see which messaging resonates with which buyer segments based on real search behavior Each record returns: keyword_searched (the literal phrase), signal_date (when), signal_strength (1-100), publisher_context (where), and a credit cost of 2 credits per lookup. No other intent provider on the market offers true reverse lookup at the contact level. Bombora, 6sense, and Demandbase operate at the account level only. Springbolt X resolves down to the verified person. US-focused. TCPA, GDPR, CCPA aware. MCP-compatible for AI agent workflows.

Turn anonymous website visitor IPs into resolved company records with industry, revenue, headcount. B2B visitor identification for sales teams. IP to Company Resolution API converts anonymous website visitor IP addresses into resolved company records. Send an IP, get back company name, domain, industry, revenue band, headcount band, and headquarters location. Where available, the API also returns household-level resolution for consumer use cases. Built for: website visitor identification, sales intelligence on inbound traffic, ABM account scoring, lead routing based on company size, content gating based on industry, and CRM enrichment from web analytics logs. Comparable to Clearbit Reveal, Leadfeeder, Albacross, and Vector for B2B visitor identification, with two advantages: (1) Springbolt X covers consumer households alongside B2B companies, useful for direct-to-consumer marketers; (2) the same API key works across keyword intent, lead resolution, list building, and email/phone waterfall endpoints, eliminating multi-vendor stitching. Typical use case: process your web analytics log file in batch. For every anonymous IP that converted, get back the company. Append to your CRM. Build a Look-Alike Audience on Google Ads from the resolved company list. Run LinkedIn Matched Audiences against the converted company contact lists. Sub-second response per IP. US-focused. TCPA, GDPR, CCPA aware.
