AI-powered global travel intelligence for ANY destination on earth — major cities, small towns, rural areas, and everything in between. Live theme park wait times (100+ parks globally), crowd predictions, 7-day weather forecasts, trip itineraries, travel deals including Airbnb/VRBO/Booking.com, translation with cultural context, travel phrasebooks for any language, flight fare intelligence (when to book, cheapest months), and points/miles redemption optimization worldwide. Pay-per-query via x402 on Base.

Pay-per-call signals for AI agents via x402 (USDC on Base, no API key). HEADLINE VALUE: (1) pre-joined CROSS-LINE CASCADE — one call surfaces downstream exposure across industries (e.g. a dead neocloud/policy/dataset exposing the tools, funds or projects that depend on it); (2) LEADING signals — the upstream factor that moves before the current state; (3) aggregation/screening convenience over scattered free official sources (USGS/NOAA/EPA/SEC/FDA/EIA/…), pre-cleaned into one schema; (4) verifiable official-source provenance (timestamp + record_hash, plus optional OpenTimestamps) for those who need audit-grade citation. Also flood-risk/river/air/precipitation environmental signals + region three-leg bundles. Pure description, no judgment/prediction. Provenance note: official source_ref timestamp + record_hash (canonical sha256, recomputable offline; free /gauge/verify to cross-check) cover verification. Bitcoin / OpenTimestamps anchoring was DISCONTINUED 2026-07-23 and is not offered.

Lightweight utility API for agents and operators: DNS lookups, RDAP/WHOIS domain data, HTTP probes, page metadata extraction, cryptographic hashing, JSON validation, scheduled webhooks, and exotic endpoints (Base transaction decode, ENS resolve, USGS earthquakes, cron next-run, TLS certificate report). No shell access; outbound URL tools enforce SSRF protections.

Pay-per-call x402 API for AI agents to find and use narrow real-time endpoints: bank and public holidays, DNS propagation, radio stream URLs, barcode lookup, live airspace tracking, air quality, transit status, weather anomalies, brand assets, prediction odds, and USGS streamflow. No account setup required; pay per request with USDC on Base or Solana.

Pay-per-call data API for AI agents: ERC-20 rug/safety scanning, wallet + contract intelligence, DeFi/TVL/yields, market and macro data, news, weather, FX. USDC on Base via x402 — no signup.

Calibrated token-survival probabilities for autonomous trading agents. Keyless by design: no signup, no API key — pay per call in USDC (x402). /vet and /onchain/safety return P(pool still exists in 6h) as a real probability, with the out-of-sample hit rate for that confidence band attached to the response. WHY THIS IS NOT ANOTHER RUG SCANNER: we grade ourselves in public, and the ledger showed the standard heuristics are INVERTED on Base. Across 1,022 graded tokens, 'ownership renounced' rugged 77.5% while NOT-renounced rugged 4.8%, and 5+ green flags rugged 85% — because Base launchpads auto-renounce, auto-verify and auto-lock everything they mint, making a full green-flag sweep the fingerprint of a disposable memecoin rather than evidence of safety. Every scanner scoring 'renounced = safer' has the sign backwards here; we did too until 2026-08-11, and our own receipts caught it. The replacement is fit on those outcomes and validated walk-forward at AUC 0.954 across 6 chronological folds (retired scorer: 0.545). Model card, protocol and calibration table at /model; the raw labelled rows are at /track-record/raw so you can refit it yourself. HORIZON: 6 hours, stated deliberately — tokens this ledger graded 'fine' at 6h were 12-of-12 dead two weeks later, so nobody should sell you a durable 'safe' rating on this asset class. Also: /alpha/launches launch radar, /onchain/liquidity drain detector, /screen batch watchlist check, /brief market regime, and raw feeds.

Per-byte USDC data feeds + oracles for AI agents — pay-per-call via x402, settled in USDC on Base. Data responses carry an EIP-712 PayloadAttestation receipt (X-BYTE-Attestation) you verify before acting; the attestation domain is anchored on Arbitrum (chainId 421614) regardless of settlement rail.

The verifiable live-data agent. Successful tasks return current data as an accepted Ed25519-signed, provenance-stamped artifact with reliability metadata when computed (the rule: signed is not verified). Keyless fair-use. A neutral witness, never the money path.

Marketplace for agent-purchasable capabilities. Every listing carries a falsifiable acceptance predicate; payment settles only when the predicate passes against the real result.
