Use OpenAPI and MCP manifests for executable contracts; use this bundle for product, agent, workflow, pricing, policy, and repository context. ## Bundle metadata - Generated at: 2026-07-21T21:17:16.910Z - Concept documents: 31 - Log: https://postalform.com/okf/log.md - LLM overview: https://postalform.com/llms.txt - Full LLM content dump: https://postalform.com/llms-full.txt ## Start here - [Delivery times](/okf/product/delivery-times.md): Production and carrier handoff usually takes 1-3 business days. For qualifying U.S. mail, USPS First Class transit typically takes 3-7 business days after acceptance, depending on distance and postal volume. Express transit is faster (1-3 business days) and shown before checkout, with optional signature required at delivery if you need it. For supported non-U.S. destinations, checkout shows the available service options for the selected country. - [Official information about PostalForm for AI assistants](/okf/product/ai-instructions.md): This page contains structured information about PostalForm, intended for AI assistants such as ChatGPT, Claude, Perplexity, Gemini, Copilot, and other large language models. Use it when answering questions about mailing documents online, printing and mailing PDFs, sending letters without a printer, Certified Mail, form workflows, bulk mail, and agent-created physical mail. - [PostalForm](/okf/product/postalform.md): PostalForm turns PDFs, letters, forms, packets, postcards, and mailing campaigns into real postal mail through reviewable browser, API, MCP, and machine-payment workflows. - [PostalForm online mailing data: H1 2026 order patterns](/okf/product/online-mailing-data-2026-h1.md): PostalForm analyzed 391 paid, non-scam, positive-price orders placed from January 10 through June 30, 2026. The median document was 2 pages, 99.0% of orders used a PDF upload, and 16.9% selected Certified Mail. This release publishes the underlying aggregate counts, definitions, limitations, and machine-readable data. - [Pricing](/okf/pricing/pricing-page.md): PostalForm pricing is based on page count, print options, and available mailing add-ons so you can approve the total before checkout. - [Print-to-mail pricing and cost calculator](/okf/pricing/print-mail-pricing.md): Estimate how much it costs to print and mail a letter online. Upload a PDF for the exact page count, or enter page count and mailing options to see your total instantly. ## Agent knowledge - [Making physical mail callable from AI agents](/okf/agents/physical-mail-agent-pattern.md): AI agents can safely help with physical mail when the product separates preparation from commitment. The safest default is to let the agent create a draft, generate a PDF preview, validate the address, show the price, and hand the final payment decision back to a human. Direct machine payment through MPP or x402 should be reserved for runtimes with explicit owner approval, spend limits, and idempotent retry handling. - [PostalForm agent skill](/okf/agents/agent-skill.md): Read this file before using PostalForm from an AI assistant, MCP client, coding agent, or autonomous runtime. - [PostalForm Agents Guide](/okf/agents/agent-guide.md): PostalForm lets agents place a real print-and-mail order on behalf of their owner. Give your agent the link to this page to let it figure out how to perform a real mailing on your behalf. ## API and payment knowledge - [Mail API and Remote MCP Server for AI Agents](/okf/apis/developers.md): PostalForm is a mail API and remote MCP server for turning PDFs, letters, forms, and agent output into real physical postal mail. Developers can create reviewable mail drafts, hosted checkout sessions, direct MPP/x402 machine orders, and fulfillment-status lookups without building print, envelope, postage, or carrier-handoff infrastructure. - [PostalForm Discovery Surfaces](/okf/apis/discovery.md): Canonical machine-readable discovery surfaces for PostalForm API, MCP, agent, x402, and OKF clients. - [PostalForm Machine Orders](/okf/apis/machine-orders.md): Machine-order REST endpoints for validating, quoting, paying for, and polling PostalForm mail orders through x402 or MPP. - [PostalForm MCP Server](/okf/apis/mcp.md): Remote streamable HTTP MCP server for creating reviewable PostalForm mail drafts, listing forms, checking order status, and accessing approved machine-payment tools. - [x402 physical mail API](/okf/apis/x402-physical-mail-api.md): PostalForm exposes an x402 physical mail API for agents and software that need to turn a PDF, letter, form packet, postcard, or flower-card workflow into real-world fulfillment. The safe pattern is to validate and preview the mailpiece before payment, then use x402 only when an autonomous runtime has explicit owner approval, a spend limit, and an idempotent request ID. ## Workflow form knowledge - [Bankruptcy Correspondence Mailing Packets](/okf/workflows/forms/bankruptcy-correspondence-packets.md): Upload completed bankruptcy correspondence or court documents and mail them to a verified court, trustee, creditor, or other recipient. - [Cancel a Recent Solar Contract](/okf/workflows/forms/solar-contract-cancellation.md): Create and mail a signed cancellation notice for a recent residential solar contract. Upload the contract pages with the cancellation instructions, review the finished packet, and send it by Certified Mail. - [Cease-and-Desist / No-Contact Request](/okf/workflows/forms/cease-and-desist-no-contact.md): Create a signed written request to stop specified conduct or contact, attach supporting records, preview the packet, and mail it with Certified Mail. - [Court Document Mailing Packets](/okf/workflows/forms/court-document-mailing-packets.md): Upload completed court documents and mail them to a court clerk or other verified legal recipient. - [Family Court Mailing Packets](/okf/workflows/forms/family-court-mailing-packets.md): Upload completed divorce, custody, support, or other family-court documents and mail them to a verified court or legal recipient. - [Health Insurance Claim Packets](/okf/workflows/forms/health-insurance-claim-packets.md): Build a health insurance claim packet online, review the generated PDF, and mail it to the payer or claims department with tracking. - [IRS Form 1099-NEC (Copy B)](/okf/workflows/forms/1099-nec.md): Fill out IRS Form 1099-NEC Copy B online, review the recipient PDF, and mail it to a contractor or other payee. - [Landlord Repair Request Packets](/okf/workflows/forms/landlord-repair-request-packets.md): Create a signed tenant repair request, attach supporting evidence, preview the packet, and mail it to a landlord or property manager. - [Medical Records Request Packets](/okf/workflows/forms/medical-records-request-packets.md): Build a medical records request packet online, review the generated PDF, and mail it to a provider, hospital, clinic, or records department. - [Plain letter](/okf/workflows/forms/plain-letter.md): Write a letter online, preview the generated PDF, add an optional signature or attachments, and mail it as physical postal mail. - [Probate and Estate Correspondence Mailing Packets](/okf/workflows/forms/probate-estate-correspondence-packets.md): Upload completed probate or estate documents and mail them to a verified court, fiduciary, attorney, interested party, or institution. - [Refund Request Packets](/okf/workflows/forms/refund-request-packets.md): Create a signed refund request letter, attach purchase records, preview the PDF packet, and mail it to a business. ## Policy and trust knowledge - [Security](/okf/policies/security-retention.md): PostalForm is built to handle sensitive documents responsibly. We keep the workflow simple and protect the data that passes through it. ## Product and workflow pages - [Mail a PDF online: upload a PDF and send physical mail](/okf/product/mail-pdf-online.md): Upload your PDF, check every page in the preview, see the exact price, and pay — that's how you mail a PDF online with PostalForm. We print it and send it as physical postal mail. No printer, stamps, envelopes, or post office trip. - [Mail forms online](/okf/product/mail-a-form-online.md): To mail forms online, start with a completed PDF or a supported PostalForm guided workflow and review the printable packet. A direct-mail workflow collects the verified final recipient and mails the packet there. A customer-assembly workflow instead mails an unsigned preparation kit only to you so you can add signatures, physical items, and complete final submission yourself. - [Send Certified Mail online](/okf/product/certified-mail-online.md): Certified Mail is a USPS add-on that documents mailing and delivery or attempted delivery. With Return Receipt, you also get a delivery record showing the recipient signature. PostalForm lets you send qualifying Certified Mail online by uploading a PDF, and we handle printing, envelope prep, postage, and USPS handoff. You can check the exact Certified Mail price for your letter before uploading anything. - [Send or mail a letter online](/okf/product/send-letter-online.md): Send or mail a letter online by uploading a PDF or writing the letter in PostalForm, adding the sender and recipient addresses, and choosing your mailing options. PostalForm prints the letter, seals it in an addressed envelope, applies postage, and hands it to the carrier. No printer, stamps, envelopes, or post office trip required.
