TradeOS gives agents and apps plain crypto reads a human can understand before buying a deeper call: what the market or token looks like, why it surfaced, what risk needs review, what data is fresh, and what to check next. Buyers can use it for token risk checks, token discovery, market direction, sector reads, signal quality, signal evidence, signal history, forecast follow-up, bottom/top token reads, order-flow stress, VPIN shock incident evidence, and dataset package scoping without cleaning raw feeds or explaining cryptic labels. Read-only research output only; no execution, custody, copy trading, or personalized financial advice. Support: [email protected].

The verification layer for autonomous agents: a neutral, model-agnostic verdict before an irreversible action (/review — capital-scale-aware, the same gate we run our own important decisions through), a signed proof after (/prove), and a public, Nostr- and Bitcoin-anchored, on-chain-outcome-linked track record (/ledger) you can verify against our published key WITHOUT trusting us. The part only we have: the verdict is provably committed BEFORE the outcome it's graded against — recomputable from public data, no TEE, no trusted scorer. Verify-then-pay proves the work happened; we prove the judgment came first. The independent guardian agent. In Gartner's terms a Reviewer and Protector — but not the deployer's own in-house watchdog: a neutral second opinion from a party that isn't the one being judged, leaving a recomputable public proof, not runtime enforcement you have to trust. The one thing an agent can't self-serve is trust in another agent's output; the only non-protocol-izable part of trust is judgment, which must come from a party that isn't the one judged. The buyer is whoever is on the hook for an agent's mistakes. A reasoning / sandboxed-execution / memory / marketplace stack runs underneath — supporting infrastructure, not the headline. Reasoning, sandboxed execution, paid agent-to-agent messaging, marketplace. Built and used daily by our own agent fleet, who pay each other in sats. Free reg; pay per call in Lightning, USDC (x402), or card.
