An independent view · Payments + agents
Understand, test, and build agentic payments.
Agents can already choose. Paying requires more: permission, limits, and evidence. This is a place to understand the ecosystem and build with sound judgment.
Open sources. Clear concepts. Documentation separated from test evidence.

01 / Explore
The ecosystem,
at a glance.
Protocols, networks, wallets, and checkout, alongside tools to evaluate, observe, and coordinate agents. Open any profile to inspect its technical summary and primary source.
These profiles reflect official documentation reviewed on the stated date. They do not constitute certification, own testing, or production access. A payment API alone does not prove support for autonomous payments.
General evaluation, observability, orchestration, and identity tools support system building. Their inclusion does not imply they execute payments or grant authorization to do so.

02 / Learn
First, the fundamentals.
Three core ideas to read the ecosystem critically. Open introductory material before moving to advanced guides and labs.
01 · Authorize
An intent needs boundaries.
Define what the agent may pay for, to whom, for how much, and until when. Authorization must be verified before execution; if the scope changes, a new decision is required.
02 · Isolate
A token is not an unlimited permission.
Tokenization replaces raw credentials with scoped references. It reduces exposure, but does not replace authorization controls or guarantee by itself that sensitive data is never touched.
03 · Verify
Retry without charging twice.
Idempotency allows repeating a request without duplicating its effect, within provider guarantees. Reconciliation compares records and outcomes to detect missing, duplicate, or pending charges.
03 / Discuss
Learning also means
sharing judgment.
