api record

PostalForm prints and mails physical letters, documents, and forms via USPS. Typical flow: validate addresses, prepare a draft and review its price, then obtain buyer approval before complete_checkout with a compatible Stripe payment token, hosted checkout, or a direct MPP/x402 payment. For MPP, any PDF, letter, or form draft can use payment_protocol=mpp and buyer_email. Review the preview and total, then call postalform.pay_order with only the order_id and buyer-approved credential. Generated letters accept text directly; no PDF upload or browser is needed.

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • postalform.search_addresses reads unknown never probed

    Use this to search for a mailing address and return Loqate suggestions with IDs. Pass country_code to filter by country; it defaults to US. If a suggestion has type "Container" (building/complex), call this tool again with container=<id> and a refined query to drill down to type "Address". Only type "Address" is valid for order creation.

  • postalform.create_order_draft changes data unknown never probed

    Prepare an existing PDF for mailing and return the order ID, total, hosted checkout URL, and checkout session. After buyer approval, a compatible client can pass a Stripe shared payment token to complete_checkout; otherwise present the hosted checkout URL. To prepare for MPP, set payment_protocol=mpp and buyer_email; receive a PDF preview and MPP challenge, then use postalform.pay_order with the order_id after buyer approval. Draft creation never pays. For x402, use postalform.create_machine_order.

  • postalform.create_letter_order_draft changes data unknown never probed

    Prepare letter text for mailing and return the order ID, total, hosted checkout URL, and checkout session. Accepts text directly; no PDF upload or browser is needed. Letter drafts may include typed or drawn signatures. After buyer approval, a compatible client can use complete_checkout with a Stripe shared payment token; otherwise present the hosted checkout URL. To prepare for MPP, set payment_protocol=mpp and buyer_email; receive a PDF preview and MPP challenge, then use postalform.pay_order with the order_id after buyer approval. Draft creation never pays. For x402, use postalform.create_machine_order.

  • postalform.create_machine_order moves money unknown never probed

    Create a single PDF, letter, workflow-form order, or bulk letter campaign and pay through MPP or x402 after buyer approval. For bulk, provide exactly one of bulk.csv_content or bulk.recipients (JSON address objects with optional merge_fields), plus a shared PDF or text/HTML template. Omit top-level recipient fields and review campaign_url, recipient count and total. Bulk MPP orders can also use postalform.pay_order after fetching its challenge. Use this when the client can answer those challenges through Link CLI/Link MCP or an x402 wallet. Single-recipient clients with a Stripe shared payment token can instead use a draft tool followed by complete_checkout; other clients should present the hosted checkout URL.

  • postalform.pay_order moves money unknown never probed

    Get an MPP challenge or pay an existing MPP PDF, letter, workflow-form order, or bulk letter campaign after buyer approval. Use the order_id returned by any draft tool with payment_protocol=mpp or by create_machine_order. When switching from create_machine_order, omit the credential first to get this payment endpoint’s challenge. Review the preview or campaign_url, recipient count and total. No document or addresses are resubmitted. Without payment_authorization this only returns a challenge; with it, this can pay and send real mail. Reuse the same order_id on retries and follow the returned payment status.

  • complete_checkout moves money unknown never probed

    After the buyer approves the prepared order and total, pay its existing checkout session using a compatible Stripe payment token, including a shared payment token (spt_...). Pass the order ID as checkout_session_id; do not resend the document or addresses. On an interrupted request, retry the same checkout and token. Existing authorized, processing, or paid payments are reused; follow the returned status and messages.

  • postalform.get_order_status reads unknown never probed

    Read payment, processing, stored mailing/carrier status, the latest 50 public tracking events, and electronic return receipt availability. Bulk orders also return campaign_url, recipient count and per-status counts; use the campaign dashboard for individual recipients. Missing carrier evidence is null; processing or a tracking number alone does not prove mailing or delivery. This read does not pay, mail, or acquire receipts.

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/75e482398fd8c9f8/badge.svg)](https://brick.blue/agent/75e482398fd8c9f8)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we knowoff the mcp door
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
