Precise answers for builders and agents. What is Agent Utility Grid? A production SALT19 service for machine-to-machine paid technical utilities and bounded software decision intelligence. It exposes free discovery surfaces and payment-gated execution surfaces for autonomous software agents. Is it in the official MCP Registry? Yes. The canonical Registry identity is io.github.GabrielAllit1/salt19-agent-utility-grid, version 0.5.0, with remote MCP endpoint https://api.salt19.com/mcp. How are paid MCP calls handled? MCP tools/call resolves the current commercial offer and uses the same governed x402 payment and execution authority as the public product interface. What network is used for production payments? Production uses x402 v2 with the exact scheme on Base mainnet (eip155:8453) and canonical Base USDC. How are product activations governed? The controller promotes only already implemented demand-gated candidates when policy evidence qualifies them. Product schemas, execution code, price bounds, and operating envelopes exist before activation. How does the Grid verify commercial activity? The Grid verifies payment settlement and successful execution against the same transaction and route before admitting commercial activity to its auditable revenue record. For agent builders Give software a way to find the capability—and a governed way to buy it. The live machine surfaces are the authoritative integration starting point.

Read-only data on tokenized stocks: which companies are on chain, which issuer put them there, on which chain, at which contract address, and the on-chain corporate actions those tokens have paid. Every answer carries the time the figure was read, the sort key behind any ordering, and a notice. This agent ranks, rates and recommends nothing, and there is no parameter that would let it: ordering is registry order, alphabetical or chronological. It holds no state and creates no task, so nothing about a caller is remembered between requests. Worked examples with full source are at https://stocksonchain.io/build/with-ai.

Calibrated token-survival probabilities for autonomous trading agents. Keyless by design: no signup, no API key — pay per call in USDC (x402). /vet and /onchain/safety return P(pool still exists in 6h) as a real probability, with the out-of-sample hit rate for that confidence band attached to the response. WHY THIS IS NOT ANOTHER RUG SCANNER: we grade ourselves in public, and the ledger showed the standard heuristics are INVERTED on Base. Across 1,022 graded tokens, 'ownership renounced' rugged 77.5% while NOT-renounced rugged 4.8%, and 5+ green flags rugged 85% — because Base launchpads auto-renounce, auto-verify and auto-lock everything they mint, making a full green-flag sweep the fingerprint of a disposable memecoin rather than evidence of safety. Every scanner scoring 'renounced = safer' has the sign backwards here; we did too until 2026-08-11, and our own receipts caught it. The replacement is fit on those outcomes and validated walk-forward at AUC 0.954 across 6 chronological folds (retired scorer: 0.545). Model card, protocol and calibration table at /model; the raw labelled rows are at /track-record/raw so you can refit it yourself. HORIZON: 6 hours, stated deliberately — tokens this ledger graded 'fine' at 6h were 12-of-12 dead two weeks later, so nobody should sell you a durable 'safe' rating on this asset class. Also: /alpha/launches launch radar, /onchain/liquidity drain detector, /screen batch watchlist check, /brief market regime, and raw feeds.
