Data Enrichment with x402 APIs

Use the agentcash CLI to access enrichment APIs at stableenrich.dev.

Setup

See rules/getting-started.md for installation and wallet setup.

Mandatory workflow

Before any stableenrich.dev call:

1. npx agentcash@latest discover https://stableenrich.dev
2. npx agentcash@latest check <endpoint-url> — confirm request fields and pricing
3. npx agentcash@latest fetch with the schema from step 2

ALWAYS use npx agentcash@latest fetch for stableenrich.dev endpoints — never curl or WebFetch.

Never guess field names. FullEnrich people-search uses current_company_domains and current_position_seniority_level — not company_domain, person_titles, titles, or seniority. Response fields like full_name, seniority, and domain are output-only.

For social media creators, use stablesocial.dev — influencer endpoints are not on stableenrich.dev.

Person Enrichment (PDL)

Prefer profile (LinkedIn URL) or email:

npx agentcash@latest fetch https://stableenrich.dev/api/pdl/people-enrich -m POST -b '{"profile":"https://www.linkedin.com/in/johndoe"}'

npx agentcash@latest fetch https://stableenrich.dev/api/pdl/people-enrich -m POST -b '{"email":"[e-mail]"}'

Valid inputs: email, profile, or first_name + last_name + (company_name OR company_domain). No match: HTTP 200, data: null — not billed.

Company Enrichment (CompanyEnrich)

npx agentcash@latest fetch https://stableenrich.dev/api/companyenrich/org-enrich -m POST -b '{"domain":"stripe.com"}'

People Search (FullEnrich)

Start with domain + seniority; add current_position_titles only when you need exact title match.

npx agentcash@latest fetch https://stableenrich.dev/api/fullenrich/people-search -m POST -b '{
  "current_company_domains": [{"value": "stripe.com"}],
  "current_position_seniority_level": [{"value": "VP"}]
}'

Key filters:

• current_company_domains — company domain(s)
• current_position_seniority_level — enum: C-level, VP, Head, Director, Manager, etc.
• current_position_titles — exact title match (returns far fewer results)
• person_locations, person_professional_network_urls, and 20+ other FullEnrich filters

Not valid: offset alone, company_domain, titles, seniority, limit, Apollo person_titles / person_seniorities.

Returns up to 10 people per query. Empty people → not billed.

Company Search (FullEnrich)

npx agentcash@latest fetch https://stableenrich.dev/api/fullenrich/company-search -m POST -b '{
  "domains": [{"value": "anthropic.com", "exact_match": true}]
}'

Requires at least one search filter. Paginate via search_after from metadata.

Contact Recovery (Clado)

npx agentcash@latest fetch https://stableenrich.dev/api/clado/contacts-enrich -m POST -b '{
  "linkedin_url": "https://www.linkedin.com/in/johndoe",
  "email_enrichment": true,
  "phone_enrichment": true
}'

Minerva Identity Resolution

npx agentcash@latest fetch https://stableenrich.dev/api/minerva/resolve -m POST -b '{
  "records": [{"record_id": "user_001", "first_name": "John", "last_name": "Smith", "emails": ["[e-mail]"]}]
}'

Minerva Enrichment

npx agentcash@latest fetch https://stableenrich.dev/api/minerva/enrich -m POST -b '{
  "records": [{"record_id": "user_001", "linkedin_url": "https://www.linkedin.com/in/johndoe"}],
  "return_fields": ["full_name", "personal_emails", "phones", "work_experience"]
}'

Lookup modes: by minerva_pid (fastest), linkedin_url in each record, or name/email/phone.

Minerva Email Validation

npx agentcash@latest fetch https://stableenrich.dev/api/minerva/validate-emails -m POST -b '{
  "records": ["[e-mail]", "[e-mail]"]
}'

Cost Optimization

Search before enrich: fullenrich/people-search ($0.14 if results) -> pdl/people-enrich ($0.28 if match) -> hunter/email-verifier ($0.03).

For multiple records, use parallel fetch calls — there are no bulk enrich endpoints.

FullEnrich people-search supports excludeFields to trim response size (e.g. ["educations", "skills", "languages"]).

Email Verification (Hunter)

npx agentcash@latest fetch https://stableenrich.dev/api/hunter/email-verifier -m POST -b '{"email":"[e-mail]"}'

Handling missing data

1. Re-run discover and try PDL vs Minerva vs Clado contacts
2. Verify company domain with companyenrich/org-enrich before people searches
3. Use Exa on stableenrich.dev to find LinkedIn URLs, then retry enrich
