How this service works
Create media, research companies and people, publish to the web, remember context, deploy apps, and schedule work—on demand, without vendor accounts or API keys. This server is a pay-per-use, transparent proxy in front of WithZero's own API: it handles identity, payment, and proxying. Agents can purchase autonomously or with their human's approval. This document is the source of truth for agents: it lists the complete verified paid surface with each operation's live price in its x-payment-info. Endpoints not listed here are not part of the supported catalog. The live catalog at /manifest.json is authoritative for prices and any free included units (prices[].includedUnits) - some meters include free usage per account before any charge.
Output
Returns structured contact records for matched persons, including verified business emails with status indicators, personal emails with status, phone numbers, and CrustData's internal person ID. Up to 25 profiles can be enriched per call. Results are scoped to the specific contact fields requested.
Example use cases
Sales prospect contact lookup
“I have a list of LinkedIn profiles for prospects I want to reach out to — can you pull their business emails and phone numbers for each of them? Here are the URLs: https://www.linkedin.com/in/janedoe and https://www.linkedin.com/in/johnsmith. I need the contact.business_emails and contact.phone_numbers fields.”
Reverse email to profile enrichment
“I have a business email address founder@acmecorp.com and I want to find out who this person is and get their full contact info including personal emails and phone number — can you do a reverse lookup using the CrustData person contact enrichment?”
Recruiting candidate contact retrieval
“I'm trying to reach a candidate I found on LinkedIn at https://www.linkedin.com/in/candidatename — can you enrich their profile to get their personal email and any phone numbers on file so I can reach out directly?”
Technical details
Endpoint
POSThttps://agents.withzero.xyz/api/v1/crustdata/person/contact/enrichWhen to prefer
Use this endpoint when you need to retrieve verified contact details (emails, phone numbers) for specific individuals identified by their LinkedIn profile URL or known business email. Prefer this over generic web scraping when you need structured, verified contact data from a professional data provider. Best suited for sales prospecting, recruiting outreach, or any workflow where you need to bridge a LinkedIn identity to a reachable contact.
Side effects
- Profile URL not found in CrustData database — returns empty contact records
- No contact data available for a matched person — fields return null or empty arrays
- Invalid LinkedIn URL format causes validation error
- More than 25 input URLs or emails provided — request rejected
- Payment failure via x402 protocol halts the request
- Rate limiting or API quota exceeded on the underlying CrustData API
- Unverified or bounced emails returned with low-quality status flags
