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. Operations whose x-payment-info.access is "plan" are sold on plans, not per call: they answer an unidentified call with 401 and an identified call with no covering plan with 403, never a 402. The complete verified paid surface is listed at /openapi.json, the source of truth for available operations. Each operation here carries its pricing in x-payment-info. Use the operations and details here when they meet your needs. Filtered specs contain only matching operations; if you cannot find what you need here, use search or the service 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, reserved for agents claimed by a human with a verified email.

Output

Returns a structured person record containing the requested fields — which may include basic profile details (name, location, headline), social media handles, and professional experience history — matched against the provided LinkedIn URLs or business emails, with confidence scores for email-based reverse lookups.

Example use cases

Sales lead enrichment before outreach

“I have a list of leads — can you enrich these business emails for me: cto@startup.io and founder@techco.com? Pull their basic profile and experience so I know who I'm emailing before I reach out, with at least 0.85 confidence on any matches.”

Recruiting candidate profile research

“Look up this LinkedIn profile for me — https://www.linkedin.com/in/alexsmith-eng — and give me their basic profile, social handles, and full work experience. I'm screening them for a senior engineering role.”

Investor due diligence on a founder

“I need to verify details on a founder before a meeting. Can you enrich this profile https://www.linkedin.com/in/sarahfounder and cross-check with sarah@founderco.com? I want their bio, social handles, and employment history.”

Technical details

Endpoint

POSThttps://agents.withzero.xyz/api/v1/crustdata/person/enrich?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need rich, structured professional profile data (bio, social handles, experience) sourced from LinkedIn or via email reverse lookup, without managing your own Crustdata API key or account. Ideal for B2B sales enrichment, recruiting research, or investor due diligence workflows where you want pay-per-use access with no subscription overhead. Prefer over direct Crustdata access when operating as an autonomous agent that handles payment via x402.

Side effects

No profile found for the given LinkedIn URL or email (empty result or 404-equivalent)
Email reverse lookup match falls below min_similarity_score threshold — no result returned
LinkedIn profile is private or deactivated — enrichment returns partial or no data
Invalid LinkedIn URL format causes a validation error
Exceeds 25-item limit on professional_network_profile_urls or business_emails arrays
Payment not authorized — ZeroClick payment flow fails before the request reaches Crustdata

Reviews

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
