Replace four vendor integrations with a single REST API. One key, one invoice, one set of error codes. Ship in an afternoon, not a sprint.

Built for engineering teams that are tired of stitching together half a dozen vendor SDKs.
Syntax, MX, disposable-domain and catch-all detection in a single request. Sub-mailbox probing without sending a single email.
IPv4 and IPv6 to city-level accuracy with ASN, carrier and proxy/VPN flags. Updated nightly from five upstream sources.
Resolve an email or domain to a normalized person or company profile. Job titles, headcounts, tech stack signals and more.
Submit up to 50,000 records per batch job. Poll or receive a webhook when enrichment completes. Same pricing per record.
First-party SDKs for Python, TypeScript, Go and PHP, generated from our OpenAPI 3.1 spec. Playwright-tested docs examples.
Every endpoint available synchronously or via signed webhooks with automatic retry and exponential backoff for 24 hours.
Create a key in the dashboard, export it as an environment variable, and you're done. No sales call required.
1. Sign up and grab a key from the dashboard.
2. Send the key as an X-API-Key header.
3. Parse the JSON. That's genuinely it.
import os, requests resp = requests.post( "https://api.third-party-api.com/v2/verify/email", headers={"X-API-Key": os.environ["THIRDPARTY_KEY"]}, json={"email": "ada@example.com"}, ) data = resp.json() if data["deliverable": print("✓ mailbox is safe to send")
