We build for machines that need evidence before they buy.
Script Master Labs LLC builds agent-native MCP servers, x402 pay-per-call APIs, provider-verification tools, and original machine-commerce intelligence. Our operating rule is simple: Truth First. Proof Always. Pay Only for Accepted Delivery.
How the evidence is produced
SML separates observation from inference. Live tools expose explicit readiness, source, timestamp, failure, and delivery boundaries where available. x402 ECHO retains observations with provenance and does not turn missing evidence into a claim of nonexistence. Market prices observed by ECHO are historical/current observations, not payment authority.
For a paid call, the target resource’s fresh PAYMENT-REQUIRED challenge controls the exact payment terms. A 402 challenge is not settlement proof. A signed authorization is not settlement proof. A successful sale requires settlement evidence and accepted delivery.

Six primary MCP products
Provider Trust verifies sources/providers. GhostKey inspects approved access, price and policy. SqueezeOS finds APIs/tools. x402 Gateway discovers paid APIs and inspects payment requirements while the caller controls spending. Robinhood RWA Intelligence provides read-only tokenized-asset evidence. ScriptDocs provides live software documentation and package evidence.

Source and truth policy
GitLab is the current source-control authority for active SML work. Runtime contracts and deployed endpoints are authoritative for live capability, readiness and payment terms. Historical pages, old directory crawls, cached package descriptions, screenshots and archived code are not current authority.
The goal is not to make every answer sound certain. Unknown stays unknown. Unavailable stays unavailable. Evidence should remain inspectable by the buyer or downstream agent.
Useful economics, not subscription theater
Many SML machine utilities are narrow pay-per-call primitives so an agent can buy only the outcome it needs. The free calculator lets buyers compare any monthly API price against published SML per-accepted-call economics with transparent break-even math.
