Keep the implementation private
Buyers receive the declared output, not the seller’s private origin URL, credentials, source code, hidden formula, private prompt or upstream response headers.

TOLLBOOTH
TOLLBOOTH is ScriptMasterLabs' Web3 infrastructure that turns a private API, algorithm, dataset, model, or agent tool into a machine-discoverable pay-per-execution service without publishing the implementation. It runs on x402 v2 with USDC on Base mainnet, paying out only on accepted delivery with deterministic acceptance checks.
Private Logic In. Paid Outcome Out. TOLLBOOTH turns a private API, algorithm, dataset, model or agent tool into a machine-discoverable pay-per-execution service without requiring the seller to publish the implementation.

What does TOLLBOOTH do?
TOLLBOOTH keeps the implementation private, charges per execution with a fresh x402 challenge, and proves bounded delivery with accepted-delivery receipts.
Charge per execution
Each protected capability exposes a fresh x402 payment challenge. Base mainnet is the primary rail; exact terms come from the current PAYMENT-REQUIRED response.
Prove bounded delivery
Settlement follows deterministic acceptance checks. Receipts prove the delivery state TOLLBOOTH observed; they do not claim subjective correctness, profitability or accuracy.
How does the TOLLBOOTH seller path work?
Seller intake is free. Wallet signing proves control of the intended payout wallet only; it does not authorize a payment. Activation remains operator-reviewed.
1 · Preflight
Validate method, price shape and HTTPS origin without echoing the private origin back publicly.
2 · Wallet proof
Sign the exact seller challenge with the payout wallet. Raw upstream secrets are not accepted through public self-service intake.
3 · Activate
Approved capabilities enter machine discovery and become callable through their own x402-protected execution route.
Truth boundary: a 402 is a payment challenge, not a purchase. Authorization is not settlement. Settlement is not accepted delivery. Fresh execution-origin evidence outranks cached directory copy.
What are TOLLBOOTH's machine surfaces?
TOLLBOOTH exposes six machine surfaces: the manifest, capability discovery, live payment rails, OpenAPI 3.1, a free wrap preflight, and accepted-delivery proof.
