Sourced token and wallet risk
Sourced token and wallet risk. Combines the Base token-report risk tier and flags, available DEX market data, and wallet-audit risk tier, flags, account nonce, and native balance. Returns the underlying indicators separately; it does not generate buy/sell recommendations or calibrated confidence, and does not evaluate holder concentration. The account nonce is not full transaction, token-transfer, or trading history. Use as one input before a Base trade.

Sources API
The news and X/Twitter evidence behind Quotient's prediction-market forecasts: recent articles and market-relevant posts for up to ten markets, in published order, each with a relevance score, reasoning, evidence quote, source tier, and author. Use this to see what is actually moving the odds on geopolitics, elections, macro, and policy markets, to audit a forecast, or to build a news feed filtered to tradable events.

South African Sa Id Number Validation API
South African SA ID number validation: Structural validation of a South African identity number with safe decode: Luhn check digit, birth date, gender and citizenship segments (citizen or permanent resident). The structural step in KYC, KYB and customer onboarding or due diligence workflows: derive date of birth, age, gender and citizenship without storing the identity. Stateless, never stored or logged (POPIA-conscious by construction).

Sovereign Debt API
Combines the general government debt ratio, the budget balance, nominal GDP growth and the long-term government bond yield into a debt pressure reading. The quantity that decides the trajectory is the differential between the interest rate and the nominal growth rate: below zero the debt ratio falls by itself even while running a deficit, above zero it rises even with a balanced budget, and reporting a debt ratio without that differential is the most common way public finances get read wrongly.

Speaker Rename API
Takes a transcript, SRT or WebVTT text and a mapping from labels to names, e.g. {"Speaker 1": "Anna Weber", "S2": "Interviewer"}, and replaces each label where it marks a speaker: at the start of a line before a colon, and inside WebVTT voice tags <v Speaker 1>. Words inside sentences that merely look like a label are not touched. The answer counts replacements per label and lists speaker labels found in the text that have no name in the mapping. Pure text processing on this machine.

Species Occurrence API
Retrieves occurrence records for a species within a radius of a coordinate and returns each with what makes it usable or not: the observation date, the coordinate uncertainty in metres, the basis of record — whether it is a preserved specimen, a human observation or a machine detection — the publishing dataset, and the licence of that record.

Species Taxonomy API
Takes a scientific or vernacular name and returns the accepted taxon it belongs to, with the complete classification from kingdom down to species, the taxonomic authority, the GBIF key and any linked identifiers. The distinction the response keeps is the one that matters for anything downstream: whether the name you supplied is the accepted name or a synonym, and if it is a synonym, what the accepted name is.

Size, colour scheme and linear or logarithmic intensity are selectable. Rendered locally with ffmpeg; returned inline as PNG base64. Nothing leaves this machine.
