US address autocomplete API
A developer preview of a US address autocomplete API for checkouts. It runs locally against simulated data so the design can be reviewed before any live service exists.
Not a live service. No hosted API, no live keys and no real address data exist yet. A live service needs a signed data license, which has not been granted. Until then, every response says
"source": "simulated".What works today (local prototype)
| Capability | Status |
|---|---|
| Autocomplete and address selection with unit drill-down | Local prototype |
| Secret and publishable test keys, origin allowlists, rate limits | Local prototype |
| Accessible browser widget | Local prototype |
| Console: keys, usage, simulated billing | Local prototype |
| Hosted API, live keys, licensed address data | Planned |
| Address verification, webhooks, SDKs, platform plugins | Planned |

- Quickstart — run the prototype and make a first request.
- Authentication — secret and publishable keys.
- Autocomplete and selection — the checkout flow end to end.
- API reference — generated from OpenAPI 0.2.0.
