Sovereign Knowledge Vending for Autonomous Agents

Monetize structured, high-value enterprise knowledge directly to AI agents over HTTP 402 with XRP Ledger drops and Base USDC settlement. Zero cloud hosting, zero data custody surrender.

● Interactive x402 Wire Handshake Simulator

Node: austin-node.storeback.io:8090

Step 1: Unauthenticated Buyer Request

External AI Agent issues GET query without payment proof.

Step 2: Settlement Rail Selection

Buyer signs 500,000 drops (0.50 XRP) micropayment to host address on XRPL.

Step 3: Verification & Synthetic Stream

Host node verifies on-chain drops, executes deterministic differential privacy, and streams synthetic JSON.

Live Wire Stream:

// Click 'GET /v1/vault/storeback/query' to initiate the protocol handshake...

Dual-Rail HTTP 402 Wire Format

Standardized challenge headers supporting both XRP Ledger drops and Base USDC micro-units:

X-402-Price-Drops: 500000

X-402-Price-USDC-Micro: 500000

X-402-Nonce: 7f2e1a9b...

X-402-Digest: 9a8b7c6d...

Deterministic Differential Privacy

HMAC-SHA256 seeded Laplacian noise defeats Law-of-Large-Numbers averaging attacks across repeated queries:

seed = HMAC(salt, id:field:val)

u = uniform(seed) - 0.5

Context-free entity scrubbing with referential graph linkage (L=1.0).

Live Vault Query Engine

Strict schema allowlists query local SQLite stores with zero raw OCR or purchase line item leakage:

inventory_items → INV-xxxx

catalog_services → SVC-xxxx

Real-time dynamic dataset counts in JSON-LD catalog manifests.

Official Client SDKs

Integrate Storeback knowledge queries into any autonomous agent framework:

cargo add x402-engine

pip install storeback

npm i @storeback/sdk
