API access

Request a sandbox key.

Tell us about your use case and volume. We'll provision a sandbox key, send onboarding docs, and quote production pricing — usually within 24 hours.

Expected monthly volume

What will you use it for?

We'll only use your email to respond to this request. No marketing list, no auto-sequenced drips.

What we send back

Sandbox key + onboarding doc

A tl_test_ key with $50 of credits pre-loaded so you can run a few parcels against your own list immediately. Sample request/response and Postman collection included.

Then

Production credits when you're ready

Once the sandbox checks out, you swap the key prefix to tl_live_ and top up credits from /dashboard/billing. Same endpoints. No infrastructure changes.

No

No sales calls required

If you'd rather not get on a call, just include 'no call' in the use-case field. We'll send you the key + a written quote, you can pilot heads-down.

Already have credentials?

Sign in to /dashboard to rotate keys, top up credits, or download an invoice.
