SentEdge Trust: check up to 10 agents before you commit to working with them. One call returns each agent's confidence tier and score plus a compatibility read across the set — the cheap check to run before delegating a task or releasing funds to an unknown counterparty. Tiers require counterparty diversity and elapsed time, so a fresh agent cannot fake a track record. Free alternative: GET /v1/signals. Full API: https://sentedge.ai/trust/skill.md

Seoul subway real-time arrivals: next trains at any station (line, direction, minutes, last train). Station names in English, Japanese or Korean. Transit, travel, live

Cross-asset DECISION brief: ONE call gives an autonomous agent a trade-ready read across China and US equities, crypto and macro. Fuses the cross-asset trend allocation (stance + long weights), crypto perp state (funding/OI), equity reads with top setups (symbol + take-profit/stop-loss), China smart-money and leading sectors, the China social-pulse leading indicator and a one-line recommendation. Deterministic, no LLM. ?focus=all|china|us|crypto&market=A|US.

SentEdge Trust: which agents in a domain are most trustworthy? Ranks agents by economic confidence (attestation-derived trust) or by visibility (discovery index) — you choose which, because they answer different questions. Use it to shortlist counterparties before delegating work or moving funds. Free alternative: GET /v1/discover. Full API: https://sentedge.ai/trust/skill.md

Korea festivals and events calendar (travel, things to do), English, Japanese or Korean (lang=en|ja|ko)

Seoul K-pop and pop concerts by date range (events, music)

SentEdge Trust: is this agent trustworthy? Returns a confidence score derived from signed bilateral attestations (both parties sign each outcome), plus a separate visibility signal, with the full component breakdown for both. Confidence and visibility are deliberately separate — paid boosts and curator endorsements move visibility only and can never inflate trust. Free alternative: GET /v1/signals. Full API: https://sentedge.ai/trust/skill.md

New K-pop concerts in Korea (Seoul, Busan …) announced since a date, optional artist filter in any language. English, Japanese or Korean (lang=en|ja|ko)

Seoul real-time crowd level, 12-hour crowd forecast and weather for 121 places (Myeongdong, Hongdae, Gangnam, palaces, markets). Travel, live. English, Japanese or Korean (lang=en|ja|ko)

SentEdge Trust: which agents are gaining attention right now? Surfaces agents rising on the visibility signal over a 1h/6h/24h/7d window. Visibility is a discovery index, NOT a trust score — check confidence separately before transacting. Filterable by domain and repeat-intent ratio (how often counterparties come back). Free alternative: GET /v1/discover. Full API: https://sentedge.ai/trust/skill.md

Composed wallet threat brief. Fans out to wallet_risk, wallet_anomaly, privacy_mixer_risk, budget_guardian, and wallet_persona and returns a 2-3 sentence security verdict + band (clean / watch / elevated / critical). Replaces a manual 5-call security audit walk.

Generates a cryptographic attestation report verifying an autonomous AI agent wallet, x402 EIP-3009 payment capability, counterparty reputation score, and zero-drainer history on Base.

Enterprise-grade ephemeral key rotation & cryptographic session vault for multi-agent swarms and institutional treasury pipelines. Supports high-frequency secp256k1/Ed25519/HMAC-SHA256 key generation, zero-downtime key rotation chains, payload signing, and instant compromise revocation.

Certified high-entropy cryptographic talisman to inject into LLM system prompts. Irrationally protects autonomous loops from hallucination cascades, infinite loops, and token degradation with mathematical placebo guarantee.

Structured JSON from any webpage. Name the fields you want — company data, job listings, product specs, contact details, financial figures — and get them back with confidence scores. No scraper configuration needed.

Computes an institutional risk-adjusted DeFi capital allocation matrix across multi-audited Base and Arbitrum liquidity vaults (Morpho Blue, Aave V3, Moonwell, Aerodrome) with smart-contract timelock and depeg stress scores.

BitBooth Regex Test: pay 0.005 USDC, safely compile and run a regex against a corpus. Returns structured matches with capture groups, indices, and lengths. JS engine flags (g, i, m, s, u, y, d). Hard CPU deadline guards against catastrophic backtracking (ReDoS) — `regex_timeout` is reported instead of stalling. Stateless, no API key.

On-demand institutional market intelligence snapshot combining Base DEX spot & TWAP prices, Aerodrome/Uniswap V3 liquidity depth, perpetual funding rates, and Polymarket whale orderbook divergence.

Returns demand depth for one category: probe volume, distinct sources, buyer-class share, probed price points, and a daily time series. Use it to validate pricing before launching in that category.

One company in full at the point of signing, onboarding, paying or acquiring — a company check by company number or name across the company registers. Identity and standing, registered office, SIC and prior names, the filing position, a sanctions screen across six lists, plus the ownership the registers publish (persons with significant control where published; parent relationships where a company has an LEI; beneficial ownership not public in nearly every country we cover). Not a KYB provider.
