Supplier Pricing Snapshot

What Is Physical Mail?
Agent physical mail is the operational layer that lets an AI agent validate, buy, and track real-world mail jobs programmatically. In practice that means quoting a paper letter before paying, creating the paid send, polling fulfillment after the order exists, and sending postcards through the same routed surface.
Direct integrations usually split those tasks across different suppliers and request contracts. One provider may handle standard letter fulfillment, another may specialize in postcards, and each tends to expose its own order, payment, and status semantics. That fragmentation makes route choice, pricing, and fallback brittle inside the agent.
AgentRouter keeps those flows behind one post domain. The agent can compare current live supply, route through the shared MPP wallet, and move from quote to send to status without rebuilding the integration every time mail providers or transport details change.
Top Scenarios
Validate the PostalForm order payload first and return the live quote before the agent commits to a paid mail job.

Quick Start
Get an API key, ask AgentRouter to recommend the best route for the job, and execute through one shared wallet instead of wiring each provider separately.
Step 1
Enable the API once
Create one AgentRouter API key that can be reused across all live domains and capabilities.
Step 2
Recommend the route
Let AgentRouter compare the current routes, prices, and route availability before the first execute call.
Step 3
Execute the capability
Run the selected workflow through the chosen route while AgentRouter handles pricing, wallet debits, and upstream settlement.

Pricing By Task
These examples translate the current live route prices into workflow questions operators usually evaluate before shipping a domain into an agent.
| Task | Route | Price | Notes |
|---|---|---|---|
| Quote one PostalForm letter | PostalForm (post.letter.quote.postalform.mpp) | 0 credits ($0) | Validate the PDF and addresses before the paid mail order is created. |
| Send one PostalForm letter | PostalForm (post.letter.send.postalform.mpp) | 3,400 credits ($3.40) | The verified live proof used a one-page PDF and manual sender and recipient addresses. |
| Poll one PostalForm order status | PostalForm (post.letter.status.postalform.mpp) | 0 credits ($0) | Use this after the order already exists to fetch current fulfillment state at zero credits. |
| Send one digital postcard | Papercut (post.postcard.send.papercut.mpp) | 1,000 credits ($1.00) | Digital postcard send on the live Papercut route using roast + github_username. |
| Send one physical postcard | Papercut (post.postcard.send.papercut.mpp) |
Why AgentRouter
Recommendation happens before execution, so the agent can compare current route supply and pricing instead of hard-coding one provider forever. The same routed contract stays stable even as provider coverage or transport paths change underneath.

Use PostalForm for standard letter quote, send, and status workflows. Use Papercut when the workflow is postcard-specific and may be either digital or physical.
No. The current live launch surface is MPP-managed, so AgentRouter handles route execution and settlement through the shared wallet flow instead of requiring separate PostalForm or Papercut keys.
Yes. PostalForm quote, send, and status plus Papercut postcard send were all re-verified live on April 28, 2026.
