# Address Standardization

`POST /v1/address-standardization`

## Request

- Base URL: `https://agent.pocket.network`
- URL: `https://agent.pocket.network/v1/address-standardization`
- Auth: none required

Rule-based postal address normalization: uppercase a free-text US address, expand standard abbreviations and split out the state and ZIP when present (usps-basic-v1). It does not validate or geocode the address, and adds no ZIP that is not in the input. POST /v1/address with {address}. Deterministic. Pay per request in USDC; no account, no API key.

## Request body

- object: The request body for POST /v1/address.
  - `address` string, required: A free-text postal address.

## Response `200`

The upstream response, served after payment settles.

- object: For POST /v1/address, a JSON object with original, standardized, state, zip and the ruleset used. The exact shape is the service's own and is not pinned here; errors return a JSON object with an `error` field.

## Other responses

- `400`: Malformed request.
- `402`: Payment required. The x402 v2 terms are in the PAYMENT-REQUIRED header and, identically, in this body; sign the chosen option and retry with the PAYMENT-SIGNATURE header. The receipt arrives in PAYMENT-RESPONSE.
- `503`: This service is not currently available to serve.
