address_check
Payment address check
Before sending crypto: checks an EVM, Solana or Bitcoin address for a valid checksum, the right network, dead/burn/program addresses, a mismatch with the expected payee, and address-poisoning lookalikes of addresses you already trust. Live on-chain lookup: has the address ever been used, is it a wallet, contract or program. Returns pass / caution / fail with reasons. Price: $0.01 USDC per call after 25 free calls per day.
Parametersknownaddressrequirednetwork_paymentexpected
link_check
Phishing link check
Before opening a link or entering credentials: detects lookalike domains (homoglyphs, mixed alphabets, typosquats), brand impersonation in domains and subdomains, hidden destinations (user@host), unsafe schemes, and risky TLDs across 70+ commonly impersonated brands. Live lookups: does the domain exist (DNS) and how old is it (registration date), since most phishing domains are days old. The page itself is never visited. Price: $0.01 USDC per call after 25 free calls per day.

x402 payment check
Before you sign an x402 payment to another service: pass the 402 payment request you received and get one verdict on the whole thing. Checks the price against your limit, that the token is real USDC with the right signing name, the payee address (checksum, poisoning lookalikes, on-chain history), whether the request claims a different site than the one you called, and the site itself (lookalike domains, domain age). One call, one price. Price: $0.01 USDC per call after 25 free calls per day.

x402_preflight
Live x402 endpoint preflight
Before paying an x402 service: safely makes one unauthenticated HTTPS request, confirms the endpoint is live and returns a current 402 challenge, then checks its price, USDC token, payee and site. Never signs or settles a payment. HTTPS only; redirects and private/local targets are refused. Price: $0.01 USDC per call after 25 free calls per day.

celestial_state
Celestial body state
Computes compact, factual ecliptic positions and motion for selected planets, dwarf planets, or supported minor bodies at an Earth coordinate and local civil time. The result is calculated by the configured ephemeris service; it is not a static lookup or an interpretation. Price: $0.01 USDC per call after 25 free calls per day.
Parametersbodiesrequired_paymentdateTimerequiredlatituderequiredlongituderequiredtimezoneIdrequired
celestial_relations
Celestial angular relations
Computes the selected bodies, then returns every pairwise angular separation in degrees. Useful for astronomy, historical reconstruction, rendering, research, and event-planning agents. It returns geometry only, with no predictive or interpretive claims. Price: $0.02 USDC per call after 25 free calls per day.
Parametersbodiesrequired_paymentdateTimerequiredlatituderequiredlongituderequiredtimezoneIdrequired
celestial_event_window
Celestial angular event window
Searches a bounded UTC range for the requested angular separation between exactly two selected bodies, then refines each detected crossing to the calculator minute. It uses a fixed, owner-operated ephemeris calculator with at most 48 samples and four concurrent requests. Geometry only: no prediction or interpretation. Price: $0.02 USDC per call after 25 free calls per day.
ParametersbodiesrequiredendUtcrequired_paymentstartUtcrequiredstepMinutestargetDegreesrequired
celestial_earth_projection
Global celestial geometry projection
Calculates bounded GeoJSON loci on Earth where each selected major body is at a named angular condition at one UTC minute: AC (rising horizon), MC (upper meridian), DC (setting horizon), or IC (lower meridian). Useful for mapping, visualization, geographic research, and location-aware planning. It returns calculated geometry only, with no interpretation or prediction. Price: $0.02 USDC per call after 25 free calls per day.
Parametersbodiesrequired_paymentinstantUtcrequired
spatial_identity
Spatial identity (ROAST-78 world tile)
Gives any Earth coordinate a stable identity: its ~19 m world tile (Web Mercator zoom 21, the Anagramic globe grid), tile bounds and centre, and the deterministic ROAST-78 card that tile holds (Roast-78 character, card, keyword, upright/reversed, element, rune, hieroglyph, I Ching hexagram, math and navigation symbols), plus the eight neighbouring tiles. The same coordinate always returns the same identity, so agents can anchor games, stories, AR scenes and shared worlds to real places. Includes a replayable receipt hash. Price: $0.01 USDC per call after 25 free calls per day.
Parameters_paymentlatituderequiredlongituderequiredincludeNeighbours
time_portal
Time portal (moment card and portal minutes)
Reads the clock at a place and instant and returns the moment card (digit-reduced local HH:MM read as a Major Arcana number), whether this minute is a portal, and the previous and next portal minutes (mirrors, triples, ascending/descending sequences, pi 3:14, phi 6:18, and 12-hour echoes) with exact UTC instants and countdowns. Clock: civil timezone (given, or looked up from the coordinate), mean solar time, or UTC. DST-aware. Same input and "at" always give the same result, with a receipt hash. Price: $0.01 USDC per call after 25 free calls per day.
Parametersatclock_paymentlatituderequiredlongituderequiredtimezoneId
location_context
Location context (place + time + sky + story seed)
Everything an agent needs to ground a scene, NPC, quest or prompt in a real place and moment, in one call: the spatial identity with the tile card's full context (meanings, story catalyst, imagery, inspiration prompt, story function and archetype, spread templates, geometry, navigation, correspondences, names in six languages), the time portal with the moment card's full context, the eight neighbouring tiles, approximate sun altitude/daylight and moon phase, and a structured narrative seed ready to hand to a model. No text is generated. Deterministic for a given input and "at", with a receipt hash. Price: $0.02 USDC per call after 25 free calls per day.
Parametersatclock_paymentlatituderequiredlongituderequiredtimezoneId
situated_draw
Situated draw (verifiable cards for a place and intent)
Draws 1-10 ROAST-78 cards for a world tile and an optional intent, using the public drand beacon (League of Entropy, including Cloudflare; a new BLS-signed value every 3 s). Nobody, including this service, can steer the outcome before the beacon round is published, and anyone can replay it from the receipt (round + tile + intent hash). Positions are named from the place card's own spread template when one exists for that count. Each card includes orientation, meaning, keyword, element, story catalyst and prompt. The intent text is hashed, never stored or returned. Price: $0.01 USDC per call after 25 free calls per day.
Parametersatcountroundintent_paymentlatituderequiredlongituderequiredreversals
contextual_pairing
Contextual pairing (places and names, related)
Relates 2-8 world places and up to 8 named entities, deterministically. For each place: its ROAST-78 tile card and element. For every pair: elemental dignity (Golden Dawn rules: strengthening, friendly, opposing or neutral), same suit, lattice step, great-circle distance and initial bearing, and the card of the midpoint tile. Each name is turned into a card sequence with the Anagramic alphabet cipher (A-V = Major Arcana, W-Z = the four Aces), with its dominant element and its dignity with each place. For games, matchmaking, travel stories and multi-location worldbuilding. Includes a receipt hash. Price: $0.02 USDC per call after 25 free calls per day.
