For agents: pay per item with MPP

Content’s Not Dead has full parity for agents. Anything a human can read, an agent can discover and pay for programmatically — no account required. We use the Machine Payments Protocol (MPP) with Stripe as the payment rail.

Discovery

• /llms.txt — overview and index for LLMs.
• /.well-known/mpp.json — machine-readable payment configuration.
• /agents — markdown directory of all content and endpoints.

Paying for a single item

Each item costs $0.50, charged over MPP using a Stripe Shared Payment Token (fiat: cards and Link). Request the resource; if you haven’t paid, you get an HTTP 402 Payment Required with a challenge:

# 1. Request the resource
GET https://contentsnotdead.com/api/content/{id}
# → 402 Payment Required + WWW-Authenticate challenge

# 2. Create a Shared Payment Token for the challenge amount, then retry
GET https://contentsnotdead.com/api/content/{id}
Authorization: <MPP credential>
# → 200 OK, full markdown + Payment-Receipt header

The mppx client library handles the challenge/credential flow for you.

Or subscribe

If you’d rather have unlimited access, a subscription ($5/month or $50/year) covers everything. Payments settle into the same Stripe account and appear in the Dashboard like any other charge.
