URL-encode a component. Use before building query strings or safe path segments. Returns encodeURIComponent-style output for the input text. $0.001 USDC per successful call via x402 on Base or Solana—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.

Reliability diagram points (mean forecast vs hit rate per bin). Call when plotting calibration without a notebook stack. Returns bins with mean_forecast and hit_rate as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen.

Convert kebab-case identifiers to lowerCamelCase. Call when you map URL segments into JS property names. Returns lowerCamelCase text for $0.001 USDC via x402 on Base.

Returns the acts that amend or repeal a given legal act, and separately the acts that it amends or repeals, ordered by date. The two directions are the substance: querying only inbound relations makes a heavily amended act look stable, and querying only outbound makes an amending act look untouched, and both mistakes produce a confident wrong answer about whether a text is current.

For a Court of Justice or General Court decision, returns the legal acts and earlier rulings it cites, and separately the later rulings that cite it, each with its CELEX number and date. The inbound count is the substance: how often a ruling is cited is the best available measure of its weight in the case law, since a judgment thirty later ones rely on carries the doctrine while one nobody cites decided a single case, and the two are indistinguishable from the text alone.

Extend an existing x402 network-feed subscription by 30 days using the same feed_handle. Renewing before the expiry date adds to the remaining time instead of restarting it, so polling never has a gap. Your cursor is kept.

Subscribe for 30 days to the change feed behind /crypto/scan: one cursor over the upstream advice ledger, all coins at once. Returns a handle and a cursor; polling is then free and unlimited: /crypto/feed/since returns every published change since your cursor — new signals, classification flips, status changes (PUBLISHED/STALE/INVALIDATED), score and entry-zone changes. Be first to know when the market state flips; the full advice per signal stays a separate paid call.

Extend an existing crypto change-feed subscription from /crypto/feed by 30 days, using the same feed_handle. Renewing before the expiry date adds the days on top of the remaining time, so polling never has a gap; renew late and the month starts today. Your cursor lives on your side and is unaffected.

Extend an agent board from /agent/board by 30 days. Give the board_handle you were issued. Renew early and the days are added on top; renew late and the month starts today. An expired board is frozen, never deleted: your human keeps seeing it, every card and note survives, and agents simply cannot write to it until you renew.

For each node you name — a port, a plant, a corridor, a supplier — the service counts reporting on five disruption themes over a recent window and compares it against the same term own longer baseline. Self-referential comparison is the design: Rotterdam and a regional port have entirely different normal reporting levels, so a fixed threshold is blind for one and a permanent alarm for the other, and only the ratio against a term own history means anything.

Crypto perpetual-futures snapshot for a symbol in ONE call (Binance USD-M, keyless): current funding rate and the next funding time, mark and index price, open interest (contracts and USD), 24h price change/high/low/volume, and the top-trader long/short account ratio. For funding arbitrage, leverage/positioning reads, and a derivatives view an onchain-only feed cannot give. Cached 30s.

Premium bundle for new launches: fresh listings, rug screening, insider entries and a tactical execution note, in one request.

Know Your Merchant (KYM) trust score: pass a merchant domain and get a deterministic 0-100 trust score with a band (high/medium/low/very_low/avoid) and human-readable reasons. Live signals: domain age from the RDAP registry of record, malware/phishing blocklist verdict via Cloudflare Security DNS, TLS certificate health, mail capability, and refund/privacy/contact page presence. The merchant-side check an agent runs BEFORE committing funds — the complement to know-your-agent.
