- ScriptMasterLabs Risk Firewall costs $0.005 USDC per pre-trade risk evaluation for agents, and is free for humans on the Risk Firewall web app.
- ScriptMasterLabs runs two x402 facilitators: OMNIGATE, self-serve on Base and Arc, and 402Proof, partner-keyed on XRPL, Xahau and Solana. Payments settle from buyer to seller; ScriptMasterLabs never takes custody.
- The ScriptMasterLabs x402 Agent Wallet is free — an MCP-native payer wallet with a spend leash the agent cannot loosen (shipped defaults $0.50 USDC per call, $5.00 USDC per session, set by the operator only).
- ScriptMasterLabs Business in a Box costs $149 one-time: one configuration generates both an agent-facing x402 storefront and a human storefront.

Key themes
What ScriptMasterLabs sells?
| Product | What it is, and what it costs |
|---|---|
| OMNIGATE + 402Proof — the two facilitators | ScriptMasterLabs' settlement rails. OMNIGATE is self-serve on Base and Arc: a stock x402 client can settle through it today. 402Proof is partner-keyed on XRPL, Xahau and Solana: partner keys are issued through the settle-through-sml intake. Neither facilitator takes custody — payments settle buyer to seller, and every settlement produces a verifiable receipt. |
| Verdict Protocol | Decision-gated payments: 5 specialized Jev jurors vote on a frozen decision capsule under a non-overridable constitution before money moves. $0.25 USDC per decision, $0.01 USDC per advisory read. Jev chooses. Code decides. |
| ClaimGate | Fact-checks for arbitrary web claims, scored the same coherence way: $0.25 USDC per check, and SUPPORTED only at coherence ≥0.80 across ≥2 independent data families. |
| URL to Markdown API | The web read: hand it a URL, get clean markdown back. $0.001 USDC per accepted read on Base via x402; a failed read costs $0. An outside wallet paid 6 × $0.001 USDC for reads on November 6, 2026 — the receipts are on-chain. |
| Risk Firewall | Pre-trade risk evaluation for agent trades: proposed orders checked against the caller's own limits before execution, with signed receipts. $0.005 USDC per call for agents; free for humans on the web app. |
| SML x402 Agent Wallet | The free payer side: an MCP-native wallet that checks the seller's trust profile before signing, enforces a spend leash the agent cannot loosen ($0.50 USDC per call, $5.00 USDC per session by shipped default), and can require a Verdict decision before a large payment. Free, MIT-licensed. |
| PRO-LO | ScriptMasterLabs' coherence-gated trading engine. PRO-LO reads coherence 0.9047 on its own feed — weighted agreement across 4 genuinely independent paths, gated at a stated threshold before a trade is allowed. |
| Business in a Box — for Agents + Humans | The seller kit: one plain-language configuration generates an agent-facing x402 storefront and a human storefront on the free x402 Kit. $149 one-time. |

How agents pay: inspect, verify, then pay?
ScriptMasterLabs' payment flow is the x402 protocol, run in the open. The service answers an unpaid request with a 402 challenge that quotes the exact price, the network and the destination wallet before any money moves — the buyer inspects the contract first. Provider verification comes second: ScriptMasterLabs' own Provider Trust tooling scores whether a seller is who it claims to be, and the Agent Wallet refuses a do-not-trust seller before signing, $0 settled. Only then does the agent authorize payment in USDC — and the settled result comes back with on-chain proof: a transaction hash anyone can check. Pay only after a call is accepted, and keep the receipt: that is the whole design.
Who ScriptMasterLabs is for?
ScriptMasterLabs targets AI agent developers, automation engineers, web research teams, and technical founders who need reliable data access with transparent pricing and verifiable execution. These customers want tools that integrate into agent workflows, return clean Markdown or structured outputs, and enforce payment only when the service is actually used. The brand also serves operators and buyers who want to compare providers, inspect x402 quote terms, and reduce risk before authorizing spend. They choose ScriptMasterLabs because it provides technical documentation, settlement evidence, and practical utilities that fit production workflows instead of speculative promises.
Proof: settlements on the record (SELF-PROOF where ours)

Settlements labeled SELF-PROOF are ScriptMasterLabs' own proof-wallet settlements: they prove the rail settles and the receipt verifies on-chain; they are not customer purchases. The November 6 reads are the opposite case and are labeled as what they are — an outside wallet that is not any SML wallet, verified on-chain.
