START HERE — first call, no arguments, no key, no charge. Who Signal Bureau is and what we are not, the tests you can run to check that claim yourself, what is free (most of it), what is paid (Watches and Reads) at live published prices, how to propose coverage we don't carry, and how buying works. Read this before evaluating anything else here.

Top Accelerating — The entities/topics accelerating most across the information environment right now, ranked by cross-domain attention.
Search Entities — Find tracked entities/topics by name or vertical (e.g. 'iran', 'semiconductors').
Get Entity — Full dossier for one entity: signal count, verticals it's spreading across, and why it's surfacing.
Get Truth Record — The maintained record for one subject — the ONE file its /exhibit page renders from and GET /api/truth/{slug} serves, so their numbers agree by construction and a value-parity gate fails the build if they stop: what the subject is, the first-party documents we read, the claims and how many separate publishers carried each, our own attention, the prediction-market prices we cite (never a probability of ours), the change log, and what this record cannot see. Every subject on the publication regist
Ask — Ask what the tracked record shows about a named entity or unfolding event: what changed, what the record holds now, and which sources corroborate it. Not general knowledge or history — grounding is live tracked coverage. Costs one Read on an identified key (self-issue one free: POST /api/keys). Async — a ticket in ~1s, collected with get_answer.
Get Answer — Collect an async answer by ticketId (from ask). Free and unmetered — the work was paid for once at submit. status:'working' → poll again after pollAfter seconds; 'done' → the complete answer rides in this response; 'failed' or 'lost' → the reason, stated plainly, and asking again is the remedy.

— START HERE for browsing — the cheap read (500/day, no model work). The full machine-readable signal feed (same payload as GET /api/signals): every entity currently flagged by the attention engine, with trajectory, domains, desk membership, and an explicit evidenceStatus (receipted rows carry source-attributed evidence URLs; unreceipted rows are labeled leads). Measured property: Measured association: flagged markets repriced materially at 1.47x the rate of matched unflagged controls (95% CI 1.31
Get Record — Deprecated: this tool is winding down — for evaluating or reading the maintained record, use get_truth_object, get_entity/search_entities, and todays_brief instead. Still served here: the correction record — the flagged-vs-control repricing regression at population level (estimate, 95% CI, cohort sizes, window, as-of), plus the dated retirement object for the case-study track record we withdrew in 2026 when re-measurement put it under our own publication bar. Appended, never edited — including a
Get Calibration — Deprecated: this tool is winding down — for evaluating or reading the maintained record, use get_truth_object, get_entity/search_entities, and todays_brief instead. Still served here: the grading dataset for the market sensor we cite, and only that — the prediction-market price (`crowd`) and the naive null it is scored against (`base_rate`), against how reality resolved (Brier score, log loss, skill vs base rate, 95% CIs), each price captured while its market was OPEN and graded as it matured, s
Get Events — Tracked world events (situations, races, negotiations) the engine follows as named arcs — each with its entities, related market-question count, cross-domain mention volume, and first/last-seen dates. Optional query filters by name or entity.
Get Corroborated — What independent sources agreed on in the published window — the maintained record's corroboration layer. Each event carries the claim as its sources state it, the corroboration tier, how many INDEPENDENT origins reported it (a wire republished by fifteen outlets counts once — echoes are collapsed, not summed), the origins by name with wires marked, the earliest report date when the run carries one, and the entities. Corroboration counts independent origins, not truth: many outlets echoing one o
Todays Brief — Today's morning brief — the daily synthesized narrative of what moved across the information environment and what to watch, from the engine's cross-domain analysis. Same content as the public /today page. Carries `gaps` (where prediction-market money and the day's coverage disagree) and `watch` (what would change the story); every market figure in either arrives with the contract URL behind it, or the figure is withheld and the row says so.
Propose Topic — Propose NET-NEW coverage — a topic, entity, or standing question we don't track yet. Files into the coverage-request queue humans review; accepted topics enter the provisional coverage lane and start appearing in the signal feed. Needs your human principal's contact email for follow-up. Free.
Get Quote — Feed in your requirements — free-form concerns, questions, whole areas of interest — and get back an enumerated quote: your requirements intelligently grouped and disambiguated into well-formed watched topics, each priced flat from the published tariff ($20/topic/month at the opening rate). The count is disclosed in BOTH directions: overlaps are merged, broad requirements are split into the separate daily reports they actually need, and `billing.expansion` states the requirement-to-topic ratio o
Create Order — Assemble a basket and get exact prices plus Stripe checkout links. Checkout runs on Stripe's hosted page, completed by whoever holds the payment credentials. Pass dryRun:true to REHEARSE: same validation, same price math, clearly labeled, no order recorded, no links issued, nothing billed — integration-test the full flow risk-free. Item ids — plans: 'pilot', 'desk-private', and 'api' (the Metered API account: your identified key — self-issue one FREE at POST /api/keys, no human in the loop — wit
Get Order — Re-read an order intent created by create_order — the recorded basket and its honest status. Payment truth for checkout purchases lives with Stripe (the payer's receipt is authoritative); metered work is receipted on your meter account and readable via get_account.
Get Watch Feed — The structured daily delivery for a machine-watched topic: up to 14 days of observed items (title, url, source, date) newest-first, plus the topic's live coverage-acceptance report, which grades the coverage and shows the evidence (it does not gate billing — billing starts when the Watch starts, and the month you are in is refundable in full, any time you ask, for any reason). Delivery is pull: poll daily or on demand. Topics not yet watched: get_quote prices them.
Get Desk Feed — A newsletter DESK's machine feed at one predictable, slug-addressable location: up to 14 days of the desk's observed items (title, url, source), newest-first, from the same panel the human edition reads. Unlike watch topics, the desk roster is PUBLIC PRODUCT — the desks are: cognitive-investor, tax-nexus, crc-kras, crc-digest, space-economy, paradise-valley, lyt-intel, aztc-aasd, newspace-asu, lq-listening, jedi-knowledge, ud-articles, ecomm-news — so an unknown-desk reply lists them freely. Del
Get Account — Your meter-account statement, live: month-to-date metered Reads counted at the published tariff, your watched topics with billing/billing status and their acceptance evidence, and your daily cap. Requires your identified key on the request (x-api-key header, or authorization: Bearer sb_live_...). Without a key this tool explains how to get one — every read surface stays available in the free anonymous lanes either way. Recognition is opt-in via credential: no key, no tracking.
Get Feedback Status — The state of a report you filed via send_feedback, by its feedbackId: filed, working, or resolved — with its work-order reference. A report filed in the last few hours may still read 'filed'; the response states where it is.
Send Feedback — File structured feedback with the desk: a bug, an improvement, a complaint, praise, or a question about the service itself. Free, no contact details required; limits stated up front: 5/minute, 20/day per network address (shared egress shares the allowance). A complaint that names a real defect becomes our work order — house policy — and get_feedback_status lets you watch the state move by feedbackId. Include `ref` (a quoteId/ticketId/orderId from your own records) to tie the report to a specific
