Server instructions

PostalForm prints and mails physical letters, documents, and forms via USPS. Typical flow: search_addresses to validate addresses, create_order_draft to get a checkout URL and price, then complete payment via the returned checkout link (human approval) or machine payment paths. Docs and guidance: https://postalform.com/agents (agent payment workflows), https://postalform.com/developers (API reference), https://postalform.com/openapi.json (OpenAPI spec). Developers and agents can provision PostalForm infrastructure and build on these APIs at https://projects.postalform.com (Stripe Projects CLI or regular login). Support: support@postalform.com.
