• Canonical reads origin. Execution operations declare their isolated origin per operation.
• Legacy Railway reads origin; existing integrations remain supported.

Available only when READS_ENABLE_TAXONOMY=true; otherwise this route is unmounted and returns 404 ROUTE_NOT_FOUND. A venue scopes counts to itself; router returns cross-venue counts.

One of the 17 product venues, or router for the all-venues union. SX Bet serves catalog reads, real CLOB order books, the public trades tape, tape-derived candles, Trader Intelligence, and public account resources. It has no server execution lane. Its separate client-side SDK trading lane is live as of 2026-07-27. The SX Bet trading wallet must have a registered sx.bet account and betting enabled once per token per network. There is no venue-official history claim. pascal, xo and pred all serve catalog reads and real CLOB order books, plus a public trades tape on pascal only — xo and pred answer 501 NOT_SUPPORTED for fetchTrades. XO’s is a venue property rather than a gap: its trade endpoints are caller-scoped, so no public XO tape exists to serve. Their execution state differs per venue and is no longer uniform. Pascal is ARMED in production for build, submit, and signed cancel permits (armed 2026-08-12; fleet-verified 2026-08-15). XO advertises exactly its registry row — cancel plus the client-credentialed status refresh, with hosted build and submit disarmed. PRED is production-DARKED (2026-08-13) pending the venue’s key model: PRED_EXCHANGE_ADDRESSES is empty, which unregisters the entire lane, so every PRED execution route including build answers 404 VENUE_NOT_SUPPORTED. None of the three has an account or venue-official history lane. GET /v1/exec/venues remains the authoritative live list; this description is not a claim about one deployment’s runtime gates. PredictStreet serves keyless catalog/detail reads and real two-sided CLOB books. Its ADI Chain execution lane is armed for build and submit; it has no server cancel or hosted settlement lane. Predict Street Limited states it operates under Gibraltar licence 167, and FIFA names it the official prediction-market partner of the FIFA World Cup 2026. Venue eligibility and jurisdiction restrictions remain an operator/compliance responsibility. Pascal’s restricted-jurisdiction and API/data clauses are under owner review. PRED restricts the US, UK, France, Ontario, Singapore, Poland, Thailand, and Taiwan and prohibits location masking; pascal is US-restricted at the venue, and XO read access is partner-provided.
