What this server can do

21 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

audit_backtest(preset, n_trials, trades_csv, payment_signature)

Forensic audit of a backtest trade ledger ($5.00). Impossible-fill detection against the real tape, cost-adjusted expectancy, overfitting checks, verdict + grade. trades_csv: CSV text with columns like symbol, side, entry_time, exit_time, entry_price, exit_price, qty. Required: trades_csv.

check_bar_quality(bars, payment_signature)

Forensic QC on YOUR OHLCV bars before you backtest on them ($0.05). Detects impossible bars, bad prints, unadjusted splits, gaps, stale data. bars: [{timestamp, open, high, low, close, volume}, ...] (5..100000 rows) Required: bars.

estimate_execution_cost(side, symbol, order_type, notional_usd, payment_signature)

Realistic execution cost in bps for an order ($0.01). Calibrated to measured live fills (SPY/QQQ 1.5bps round-trip floor), with square-root size impact. order_type: limit_nbbo | market. Required: symbol, notional_usd.

get_pricing

FREE: price list, payment network, and payTo address for all paid tools.

get_regime_current(payment_signature)

Live market regime: STABLE/VOLATILE + confidence + position_scalar ($0.005). Validated variance detector: VOLATILE predicts ~2x forward volatility with ~90% persistence. Use for position sizing / risk gating, NOT direction.

get_regime_history(end, limit, start, payment_signature)

Historical regime snapshots, 5-min cadence since 2026-02, 417k+ rows ($0.02). start/end are ISO timestamps; limit <= 10000.

get_regime_sample

FREE: 24h-delayed market regime snapshot (taste of the live paid feed).

sygnl47_entities(payment_signature)

Tracked entity gazetteer plus today's guard state ($0.25). RETURNS: every entity SYGNL/47 listens for with its disambiguation rules attached — a country only counts when a policy instrument is nearby, "intel" does not count next to "agency", "apple" does not count next to "pie" — and, per ticker, whether it is BLOCKED right now by the earnings and liquidity guards, with the reason string. WHY IT CHANGES: a name being watched and a name being actionable today are different facts. An earnings print inside the holding window destroys move attribution, so those names are refused outright. Liquidity below $10M 20-session average dollar volume is a hard reject. A guard that could not check reports UNKNOWN and never silently passes. GUARANTEED MAX STALENESS: guard state is resolved at publish time; the response carries guards_evaluated_utc and sync.feed_age_seconds so you can judge it yourself. PRICE: $0.25 USDC. NOT A PREDICTION: this is a reference and constraint dataset, not a recommendation to trade any name it lists as allowed.

sygnl47_event_detail(event_id, payment_signature)

Full detail for one SYGNL/47 event by id ($2.00). RETURNS: the complete event — verbatim snippet (180-char cap), verification block (live vs replay, liveness reason, independent source count, consensus confidence) and market attribution (mark, benchmark, abnormal return by horizon). GUARANTEED MAX STALENESS: none — this serves events of any age including the newest, which is why it is priced at the live tier rather than the archive tier. PRICE: $2.00 USDC. An unknown event_id returns 404 and is NOT settled. NOT A PREDICTION: verified observation of a public statement. event_id example: sygnl47-20260727-192342-GM Required: event_id.

sygnl47_events_15m(limit, since, payment_signature)

Verified POTUS statement events, nothing newer than 15 minutes ($0.25). RETURNS: the same complete payload as the live tier, including the full verification and market-attribution blocks. GUARANTEED MAX STALENESS: 900 seconds. PRICE: $0.25 USDC. Appropriate for attribution and research rather than reaction. NOT A PREDICTION: verified observation, no edge claim.

sygnl47_events_1m(limit, since, payment_signature)

Verified POTUS statement events, nothing newer than 60 seconds ($0.75). RETURNS: identical schema, identical fields and identical verification block to the live tier. Nothing is stripped — only recency is. GUARANTEED MAX STALENESS: 60 seconds. The cutoff is enforced server-side on ts_utc and bound to this priced route, not to any argument you send. PRICE: $0.75 USDC. NOT A PREDICTION: verified observation, no edge claim.

sygnl47_events_archive(limit, since, payment_signature)

Verified POTUS statement events at T+24h and older ($0.10). RETURNS: the full historical record, same complete schema as every other tier — the archive is not a sample and not a degraded copy. GUARANTEED MAX STALENESS: 86400 seconds. PRICE: $0.10 USDC, the cheapest rung — deliberately kept low enough that a price-sensitive agent still has something it can transact on. INVENTORY, HONESTLY: 2 events today, both reconstructed from archived broadcast audio of one speech (2026-07-27, GM Milford Proving Ground) and labelled source: replay with sources: 1 and replay_checked: false. Two fires from one speech are not two independent observations. NOT A PREDICTION: verified observation, no edge claim, zero confirmed live outcomes.

sygnl47_events_live(limit, since, payment_signature)

Verified POTUS statement events with no delay applied ($2.00). RETURNS: newest-first list of CONFIRMED observations, same schema as every other tier: verification block (live vs replay via acoustic fingerprinting, independent source count) and market block (abnormal return vs benchmark). GUARANTEED MAX STALENESS: 0 seconds. PRICE: $2.00 USDC — the top of the ladder, because recency is the only thing the price buys. NOT A PREDICTION: verified observation of a public statement and the price action that followed. Zero confirmed live outcomes to date. since: ISO-8601 lower bound on ts_utc (narrows only). limit: 1..500.

sygnl47_feeds(payment_signature)

Broadcast feed buffer-depth map and source health ($0.25). RETURNS: per live news feed, the measured connect-buffer depth — how many seconds of already-buffered audio the source dumps the instant you connect — plus transport kind and uptime observation counts. The measurement behind it found continuous Icecast radio buffers 2-5x shallower than segmented video HLS (NPR 2.7s vs Reuters 38.3s), which is a genuinely useful fact for anyone building a low-latency listening path. STATED PLAINLY: this is buffer depth, NOT standing latency. Standing latency is a different number, it requires a simulcast we have not captured, and the cross-feed correlation available today scores below its own acceptance threshold — so no per-feed lag figure is published. We would rather return a null than a confident wrong number. PRICE: $0.25 USDC. NOT A PREDICTION: infrastructure measurement only.

sygnl47_latest_event(payment_signature)

Most recent verified POTUS statement event, no delay ($2.00). RETURNS: the single newest CONFIRMED observation — timestamp, entity and ticker named, a verbatim snippet capped at 180 characters, the verification block (live vs replay, how many independent feeds corroborated it, consensus confidence) and the market block (mark, benchmark, abnormal return at 1/5/15/30 minutes, instrument minus benchmark). GUARANTEED MAX STALENESS: 0 seconds of deliberate delay. Real freshness is bounded by publisher sync and reported in every response as sync.feed_age_seconds — measured, never assumed. PRICE: $2.00 USDC. Deliberately premium: this is verified, hard-to- replicate data and we would rather learn what one real buyer pays than what a hundred free riders sample. NOT A PREDICTION. This reports what was said and what happened afterwards. No edge claim, no win rate, no recommendation. If no event exists the call returns 404 and is NOT settled — you are not charged for silence.

sygnl47_manifest

FREE: SYGNL/47 service manifest — method, latency tiers, prices, inventory. Read this before calling any paid sygnl47_* tool. Describes how events are detected and verified (live-vs-replay acoustic fingerprinting, multi-source corroboration, linguistic guards, abnormal-move attribution), the full price ladder, and the CURRENT INVENTORY stated plainly. Inventory today is thin and we would rather you knew: 2 events, both reconstructed from archived broadcast audio of a single speech and labelled source: replay, and ZERO confirmed live outcomes. This manifest contains no event data — it is a description of the service, not a free sample. There is no free tier of the data itself, only cheaper (older) tiers.

sygnl47_subscribe_archive_30d(payment_signature)

Buy a 30-day unmetered pass to the SYGNL/47 archive tier ($100.00). RETURNS: a signed bearer token granting unmetered access to the archive tier (T+24h and older) for 30 days. The archive payload is complete, not a sample — same schema and same verification block as the live tier, only older. IMPORTANT: an archive pass does NOT authorize the live, 1m or 15m routes. Using it there returns a normal 402 with an explanation, because a pass may never widen freshness beyond the tier it was bought for. PRICE: $100.00 USDC. NOT A PREDICTION: verified observation feed, no edge claim.

sygnl47_subscribe_live_24h(payment_signature)

Buy a 24-hour unmetered pass to the SYGNL/47 live tier ($50.00). RETURNS: {token, sub_id, tier, expires_utc, max_freshness_seconds, authorized_routes}. Send the token as header X-SYGNL47-TOKEN on any authorized route and no per-call payment is charged until it expires. STORE THE TOKEN — verification is stateless by design, so we cannot reissue it. WHAT IT DOES NOT BUY: fresher data. The pass grants unmetered access to the live tier, and the server-side ts_utc cutoff applies to pass holders exactly as it does to per-call buyers. An expired token falls back to a normal 402 challenge, never to a free serve. PRICE: $50.00 USDC, versus $2.00 per live call. NOT A PREDICTION: this buys access to a verified observation feed with zero confirmed live outcomes, whose current inventory is 2 replay-sourced events.

sygnl47_subscribe_live_30d(payment_signature)

Buy a 30-day unmetered pass to the SYGNL/47 live tier ($750.00). Same contract as the 24-hour pass over a 30-day window: signed bearer token, unmetered access to the live tier, no widening of freshness beyond that tier, stateless verification, and a normal 402 fallback once it expires. PRICE: $750.00 USDC. NOT A PREDICTION: verified observation feed, no edge or win-rate claim, zero confirmed live outcomes to date. At this price you should read sygnl47_manifest first — it states the inventory plainly, and the inventory is currently 2 events reconstructed from archived audio.

sygnl47_subscription_plans

FREE: prepaid-pass plans for SYGNL/47 (the subscription catalog). x402 is per-call by design. A subscription here is a PREPAID TIME-BOXED PASS on the same rails: one payment buys unmetered access to one tier for one window and returns a signed bearer token, which you then send as X-SYGNL47-TOKEN instead of paying per call. Lists each plan with its tier, duration, price and the exact routes it authorizes. Read this before calling any sygnl47_subscribe_* tool.

trade_preflight(order, state, policy, evidence, payment_signature)

Pre-trade decision gate for AI trading agents ($0.01). Deterministic ALLOW / REDUCE / REQUIRE_CONFIRMATION / BLOCK with reason codes, an order-hash-bound approved size, 60s expiry, and an EIP-191-signed attestation. Composes the live regime detector, the measured execution-cost oracle, and YOUR policy (max_notional_usd, max_cost_bps, daily_loss_limit_usd, confirm_above_usd, symbol_allowlist, ...). order: {symbol, side, notional_usd, order_type}. evidence: {audit_score} from audit_backtest. Not investment advice. Required: order.
