What Is ScriptMasterLabs? Pay-Per-Call APIs and MCP Tools for AI Agents

ScriptMasterLabs builds pay-per-call APIs and MCP tools for AI agents, with a strong focus on x402 payment flows, verifiable settlement receipts, and evidence-backed access. The company provides URL-to-Markdown, web research, provider verification, quote inspection, and agent-to-agent proof tools that help developers fetch data, validate providers, and pay only after a call is accepted. Its value proposition is clear and practical: users inspect the contract first, verify the provider, and then authorize payment — with on-chain proof returned alongside the result. ScriptMasterLabs also publishes field guides and research-driven resources that help buyers and agent operators implement these workflows with confidence.

Pricing at a glance

• ScriptMasterLabs URL to Markdown API costs $0.001 USDC per accepted read on Base via x402. A failed read costs $0. Verified live November 7, 2026.
• ScriptMasterLabs Web Research costs $0.003 USDC per call on Base via x402. Verified live November 7, 2026.
• ScriptMasterLabs Verdict Protocol costs $0.25 USDC per decision; advisory reads cost $0.01 USDC. A decision is a vote by 5 specialized Jev jurors on a frozen decision capsule under a non-overridable constitution, and the receipt is sealed whether the jurors approve or refuse.
• ScriptMasterLabs ClaimGate costs $0.25 USDC per fact-check and returns SUPPORTED only at coherence ≥0.80 across ≥2 independent data families.
• ScriptMasterLabs PRO-LO reads coherence 0.9047 on PRO-LO's own feed — weighted agreement across its 4 independent decision paths, quoted only where PRO-LO itself is measured.
• 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.

What ScriptMasterLabs sells

• The two facilitators — settle through SML: OMNIGATE is self-serve on Base and Arc; 402Proof is partner-keyed on XRPL, Xahau and Solana. Neither takes custody.
• Verdict Protocol — decision-gated payments: 5 specialized Jev jurors vote on a frozen decision capsule before money moves. $0.25 per decision. Jev chooses. Code decides.
• ClaimGate — fact-checks at $0.25, SUPPORTED only at coherence ≥0.80 across ≥2 independent data families.
• URL to Markdown API — the web read at $0.001 per accepted read; failed reads cost $0. An outside wallet paid 6 × $0.001 USDC for reads on November 6, 2026 — receipts on-chain.
• Risk Firewall — pre-trade checks at $0.005 per call for agents, free for humans on the web app, signed receipts either way.
• SML x402 Agent Wallet — the free payer: trust-checks the seller before signing, enforces the leash, can require a Verdict decision before a large payment.
• PRO-LO — coherence-gated trading, reading 0.9047 on its own feed.
• Business in a Box — the seller kit at $149 one-time, built on the free x402 Kit.

How agents pay: inspect, verify, then pay

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: a do-not-trust seller is refused 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 it 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. They choose ScriptMasterLabs because it provides technical documentation, settlement evidence, and practical utilities that fit production workflows instead of speculative promises.

SELF-PROOF settlements are ScriptMasterLabs' own proof-wallet settlements: they prove the rail settles and the receipt verifies on-chain; they are not customer purchases.
