One API
Uniform developer access over Posteering's products. Authenticate once, reach every product you're entitled to through one consistent surface.
One integration, every product
The One API is Posteering's uniform developer access platform. Through a single integration you authenticate once, hold entitlement to the products you've enabled, and reach each one through one consistent surface — to build your own product on a combination of products, or to use any product standalone.
It is exactly five capabilities, and nothing more: identity, entitlement, provisioning, routing, and correlation. The platform holds no balance, no position, no account state, and no money of its own.
It composes nothing
The One API gives you access to each product in that product's own native vocabulary. Combining two products into one experience — a wallet, a lending product, a funding event wired to a ledger posting — is a product you build on top of this access. The platform never makes two products speak to each other on your behalf.
