Straits.live premium data
Strait of Hormuz bunker & marine-fuel feed: current VLSFO, IFO380, and MGO prices ($/tonne) for Fujairah (the world's #2-3 bunkering hub, just outside the strait and the physical fueling alternative when transit is disrupted), benchmarked against Singapore and Rotterdam, plus the derived Fujairah premium over each comparison hub. The physical-commodity read on Hormuz stress that the Brent and insurance signals do not capture.

Straits.live premium data
Strait of Hormuz shadow-fleet risk screen: the live-AIS vessel population (vessels seen on AIS within the last activeWindowHours, currently 1.5) ranked worst-first, each hull with its risk band, the typed reasons behind it (ofac_sdn, ais_dark, foc_tanker, imo_spoofed), which sanctions bodies list it (US OFAC and/or UK/FCDO), and a lastSeenAt timestamp (when the hull was last listed, not necessarily its last true AIS fix) so listing recency can be checked per row. A transparent rules engine (not ML) fusing OFAC + UK sanctions, live AIS, AIS-dark gaps, and spoofed-IMO detection into one compliance-grade screen. counts cover the screened population, that is every hull seen on AIS inside the active window, not every hull ever tracked; vessels lists only the flagged hulls (high + moderate) by default, ?all=1 adds the cleared low-band hulls. Quality-gated on live AIS; flags are best-effort from the MMSI MID (ITU-T M.585). Because the screen is bounded to the active AIS window, an ais_dark re

Straits.live premium data
Strait of Hormuz war-risk transit premium nowcast: a live MODELED war-risk insurance multiple (Nx over the peace baseline, on the published 1x-80x scale) for moving a tanker through the strait, recomputed every 5 minutes from throughput deviation (IMF PortWatch), the escalation forecast (Polymarket + Kalshi + Manifold + Brent-WTI spread), crude implied volatility (OVX), and event pressure (news and maritime RSS feeds, the PGSA incident feed and GDELT). The standing straits.live insurance-estimate multiple is carried only as a static reference (it is set manually and changes infrequently); the modeled figure is the live signal, not a divergence from that anchor. Returns a band, a curated VLCC war-premium band ($/voyage, estimated separately from the modeled multiple and not derived from it), per-driver detail, and a confidence that degrades on stale feeds or thin market volume. A modeled situational-awareness indicator, not an insurance quote.

Stt API
Takes an audio or video file by URL or inline base64 and returns the transcript: the full text, every word with start and end time and its own confidence, the utterances and paragraphs the recogniser separated, and the detected language with its confidence where no language was specified.
halowerk.com-$0.06listed
Stt Batch API
Takes 2 to 15 recordings by URL or inline base64, each with its declared length, and returns one transcript per file in the order given: full text, detected language, paragraphs, utterances, a confidence summary naming the weakest words with timestamps, and optionally every word with its timing. Billing is per started audio minute across the whole batch, at 0.017 USDC instead of the 0.02 USDC of a single /v1/stt call, at most 60 minutes per call.
halowerk.com-$0.034listed
Stt Long API
Takes a public URL of an audio or video file of up to 120 minutes and 150 MB and returns the transcript: full text, paragraphs with sentences and timings, utterances, the detected language, and a confidence breakdown naming the weakest words with timestamps; every word with its timing on request. The file is downloaded and its running time measured locally with ffprobe before anything is sent, so a recording longer than declared is refused with its real length and nothing is charged.
halowerk.com-$0.018listed
Stt Translate API
Takes an audio or video file by URL or inline base64 and returns subtitles in the target language with the timing of the original speech. The recording is transcribed with word timestamps, split into subtitle cues at pauses, six seconds or 84 characters, and every cue is translated on its own so that the number and timing of cues stay identical — this is checked on every model answer and a mismatch is retried once and otherwise refused without charge.
