# Manifolds

> Manifolds identifies and enriches product signups. Send an email address via API or webhook and get back the person, their role, and their company, then broadcast the result to your CRM, data warehouse, Slack, or any endpoint that accepts a webhook.

Manifolds is built for companies with high signup volume, roughly 1,000 to 1M signups per month. It uses proprietary data, web crawling, and LLMs to research users at signup, so sales, growth, and product teams can find the most valuable signups while intent is still high.

Key facts:

- Website and web app: https://manifolds.run
- API base URL: https://api.manifolds.run (Bearer auth; keys are prefixed mf_live_)
- Enrichment is asynchronous. POST /v0/enrichments returns a 202 receipt; results are delivered to your webhook endpoints.
- Pricing is usage-based per successful match, from $0.75 down to $0.35 depending on monthly volume, with enterprise pricing at 1,000,000+ matches per month. Unmatched emails are never charged.
- The product and pricing pages each have a Markdown version, linked from their entries below.
