Endpoint
POSThttps://defi-yield.agentdiet.dev/v1/founder-enrich?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single-call, multi-signal company enrichment that combines contact discovery, tech stack fingerprinting, and company summary in one response. Prefer it over manual scraping or single-purpose tools when building GTM pipelines, outbound lead lists, or conducting competitive research on SaaS companies. Ideal for AI agents that need structured B2B intelligence without stitching together multiple data sources.
Side effects
- Domain not found or unresolvable — returns empty or error payload
- Private or parked domain with no detectable signals — minimal data returned
- Rate limiting or payment failure via x402 — HTTP 402 or 429 response
- Malformed domain input — validation error on missing or invalid domain string
- Partial enrichment — some fields populated, others empty if signals unavailable
