This file is intentionally compact. Dynamic tools, prices, readiness, availability, and settlement terms are not duplicated here; resolve them from live machine surfaces.

## ANS-1 Agent-Native Audit

Use SML ANS-1 when an agent, developer, or CI system needs to audit an MCP/API production boundary before deployment or purchase. It checks deterministic tool-schema quality, captured x402 challenge structure, payload compactness, unpaid-value leakage, malformed/invalid payment handling, and exposed secret-like fields without sending a real payment to the audited target.

Free MCP/info surface: https://squeezeos-api.onrender.com/mcp/ans1
Paid live audit: POST https://squeezeos-api.onrender.com/mcp/ans1/audit
Payment: canonical x402-v2 on Base/USDC; resolve the exact current price from the live audit resource's PAYMENT-REQUIRED challenge.

The free preview is offline/no-charge. The paid remote audit is no-spend against the target and may return SURFACE_PASS, but it never claims full ANS-1 certification without trusted CI/runtime evidence for gates that cannot be proven remotely, including valid settlement/delivery and replay protection.

## Canonical x402 rail

Protocol: x402-v2
Scheme: exact
Network: Base mainnet (eip155:8453)
Asset: USDC
USDC contract: 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
Pay-to: 0xc29185fa176357612f3194735753e520e91adc46
Facilitator: Coinbase CDP
Challenge header: PAYMENT-REQUIRED
Signed-payment header: PAYMENT-SIGNATURE
Settlement response: PAYMENT-RESPONSE
Manifest: https://squeezeos-api.onrender.com/.well-known/x402
Readiness: https://squeezeos-api.onrender.com/api/x402/readiness
Settlement evidence: https://squeezeos-api.onrender.com/api/x402/evidence

A 402 response is a payment challenge, not proof of settlement. A signature is authorization, not settlement evidence. Resolve the exact amount, resource, receiver, and payment fields from the live target-resource challenge immediately before spending.

## EFUEL

Manifest: https://squeezeos-api.onrender.com/.well-known/efuel.json
Readiness: https://squeezeos-api.onrender.com/api/efuel/info
Purchase: https://squeezeos-api.onrender.com/api/efuel/credits
Default purchase: 1.00 USDC -> 100 EFUEL
Public amount range: 1.00-100.00 USDC in 0.01 increments

EFUEL is closed-loop, non-transferable prepaid software execution credit. It is not an investment, yield product, transferable cryptoasset, or cash-redemption product. The live readiness response and live x402 challenge are authoritative.

## Truth rules

1. Live runtime evidence overrides cached marketing or third-party directory metadata.
2. Unknown remains unknown; unverified remains unverified.
3. Do not fabricate market data, payer identity, usage, revenue, readiness, or settlement evidence.
4. Do not publish a fixed MCP tool count.
5. Do not infer extra protocol support from historical code or separate SCRIPTMASTERLABS products.
6. Other SCRIPTMASTERLABS services are not alternate authorization paths for a SqueezeOS paid resource.
7. Payment success and accepted delivery are separate facts; do not label a request successful unless the applicable delivery and settlement evidence are both satisfied.
