What is Polar?

Polar lets AI agents sign up, set up billing and complete checkouts.

Polar is now an official ChatGPT plugin and an approved Claude MCP server, so pricing, meters, credits and support can be run from a chat. Agents can create a Polar account on their own and hand it over with a claim code, hosted checkout exposes WebMCP tools, and agents can pay for buyers through Agentcard. The same release adds self-serve Stripe migrations and DNS domain verification.

What is SendOwl?

SendOwl opened its store data to AI assistants, and gave sellers a customer record at last.

SendOwl has spent 2026 filling in the parts of a digital-goods store that were missing rather than adding new selling mechanics. A Customers section finally gives sellers a person-centric view instead of reconstructing a buyer from order history; an iPhone app in beta puts revenue, orders and top products on a phone; billing-transparency work surfaced bandwidth, plan limits and overages on the dashboard; and annual billing arrived across all plans. In June it rebuilt its PayPal integration on PayPal's newer platform as Express and Standard are retired.

Polar vs SendOwl: editorial side-by-side

P
Polar
E-COMM
6.3

Polar lets AI agents sign up, set up billing and complete checkouts.

◆ Current state

Polar is now an official ChatGPT plugin and an approved Claude MCP server, so pricing, meters, credits and support can be run from a chat. Agents can create a Polar account on their own and hand it over with a claim code, hosted checkout exposes WebMCP tools, and agents can pay for buyers through Agentcard. The same release adds self-serve Stripe migrations and DNS domain verification.

◆ Where it's heading

After a summer of billing depth (credits, meter cycles, tiered usage pricing), Polar is now treating agents as both merchants and buyers. Stripe migrations target sellers ready to switch.

◆ Prediction

Expect more of the dashboard to become agent tools; the entries do not show pricing for agent-driven accounts.

SendOwl
E-COMM
6.3

SendOwl opened its store data to AI assistants, and gave sellers a customer record at last.

◆ Current state

SendOwl has spent 2026 filling in the parts of a digital-goods store that were missing rather than adding new selling mechanics. A Customers section finally gives sellers a person-centric view instead of reconstructing a buyer from order history; an iPhone app in beta puts revenue, orders and top products on a phone; billing-transparency work surfaced bandwidth, plan limits and overages on the dashboard; and annual billing arrived across all plans. In June it rebuilt its PayPal integration on PayPal's newer platform as Express and Standard are retired.

◆ Where it's heading

The July run points at a seller who wants answers rather than screens. The Customers section, the mobile metrics app and read-only agent access are three routes to the same question — who is buying what, and how is the store doing — and the agent beta is the one that skips the interface entirely. Read-only scope, 30-minute token expiry and revocation suggest SendOwl is testing appetite before deciding how far to open the API. The PayPal rebuild is different in kind: forced maintenance on a payment rail, the sort of work that consumes a quarter and yields no new capability.

◆ Prediction

If the agent beta holds up, expect write access or a scoped token model to follow, since read-only answers stop being enough once sellers want the assistant to act. General release of the iPhone app is the other near-term item these entries point to.
