The prospiq API gives you programmatic access to everything the web app does. If you're building outbound infrastructure, an internal sales tool, or just want to automate enrichment inside an existing workflow, the API is how you do it.
Who the API is for
The API is included on the Pro plan and on custom plans. It's intended for:
- Engineering teams integrating prospiq into existing pipelines
- Sales operations teams building internal tooling
- Companies whose volume exceeds what the bulk uploader can handle
- Anyone who wants to enrich contacts the moment they enter a CRM, signup form, or webhook payload
If you're on Starter or Growth and need API access, you can either upgrade to Pro or contact us to discuss a custom plan.
What you can do with it
The API exposes the core enrichment surface of prospiq:
- Single contact enrichment. Given name + company or a LinkedIn URL, return a verified email and phone where available.
- Bulk enrichment. Submit up to several thousand contacts in a single request and poll for results.
- Company search. Find decision-makers at a target company.
- Credit balance. Check your remaining credit balance for the current billing cycle.
- Webhooks. Subscribe to events like "enrichment complete" or "bulk job done" so your system can react in real time.
All API endpoints follow the same pricing as the web app — emails cost 1 credit, phones cost 10, both cost 11, empty results cost 0.
What the API doesn't do
A few things in the web app aren't exposed through the API, mostly because they don't map well to programmatic use:
- Saved lists (these are a UI organization tool — the API operates on individual contacts and bulk batches)
- Team and billing management (handled via the web app)
- CRM push (the API returns data — your system pushes it wherever you want)
What you need to use it
- A Pro or custom-plan account
- An API key, generated from your account settings
- A reasonable understanding of HTTP and JSON
That's it. No SDK is required — every endpoint is plain REST and JSON. We do publish official client libraries for Node and Python to save you a few hours of wrapper code, but you can call the API directly from any language that speaks HTTP.
Rate limits
Rate limits scale with plan:
- Pro: rate limits suitable for typical SaaS integration patterns
- Custom: negotiated based on your expected volume
The API returns standard rate-limit headers on every response so your client can back off gracefully when you approach the cap.
What's coming next
The API is launching with the platform on June 2, 2026. Documentation, code examples, and the OpenAPI specification will go live at prospiq.net/api-docs on the same day.
If you want early access to the API before launch — for example, to start building an integration ahead of go-live — email us and we'll set you up.
