DEEP DATA

One endpoint. Two depths.

Go from an IP's country to its network flags, or an email's format to its deliverability. Add ?deep=true for richer fields in a nested deep object. The route and core fields stay the same.

GET /ip/8.8.8.8
GET /ip/8.8.8.8?deep=true

BULK

Verify the whole file.

Drop a spreadsheet to verify an email list or check phone numbers, IPs, and postal codes. We detect supported columns and add the answers beside them. Priced per column. Junk is free.

DX

It just works.

Auth, errors, and docs. All exactly where you'd look for them.

X-API-Key: YOUR_API_KEY

One header

X-API-Key or Authorization: Bearer. Same key, either header. Copy it in and start calling.

{ code, message, docs, request_id }

Errors you can act on

Every failure returns the same shape: a code, a message, a link to the exact fix, and a request ID to trace it.

/docs#not_found

Docs that answer it

Every field explained. Every error paired with the fix, so the next step is always obvious.

PLANS

Big quotas. One price per team.

Upgrade when you outgrow it. Start is $20/mo for 1M requests, Pro is $100/mo for 10M. No per-seat billing.

Live checks, including email verification and carrier lookups, have their own included monthly allowances. Paid plans add optional per-check overage.
