audit_backtest | 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.
|
check_bar_quality | 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)
|
estimate_execution_cost | 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.
|
get_pricing | FREE: price list, payment network, and payTo address for all paid tools. |
get_regime_current | 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 | 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 | 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 | 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
|
sygnl47_events_15m | 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 | 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 | 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 | 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 | 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 | 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 | 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 | 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 | 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 | 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.
