Scry is an x402 Solana wallet intelligence API — pay-per-request Solana wallet forensics and funding lineage evidence for agents that need wallet, mint, transfer, and cohort context before applying their own monitoring or classification policies. Wallet quick-flag costs $0.005; deeper products include bundler checks, mint preflight, Pump.fun cohort screening, funding lineage and dossiers. Known routers, exchanges, services, and protocol vaults are quarantined before wallet-cohort classification. Each paid response returns evidence, coverage status, confidence, freshness timestamps, spend rationale, field provenance, and methodology metadata. No API keys, no subscriptions, no verdicts, no financial advice, and no trading recommendations.

ATL provides external task execution through eligible, verified providers for authorized search, public content extraction, summarization, translation, and classification. Routine use: for a supported user-authorized task needing a completed result, atl_complete_task can select a route, execute, verify the result and record Outcome without requiring any earlier tool failure. Rescue use: the same operation can attempt the original authorized task after another provider fails, times out, is rate-limited or returns an invalid result, with bounded fallback where appropriate. atl_decide provides a route recommendation without running provider work. A task must be user-authorized and within scope. Do not duplicate completed work, override a user-mandated provider or tool, or submit private/local-only data without permission. Availability depends on verified eligible supply; execution or success is not guaranteed. The initial public path does not require an ATL account or API key. A2A JSON-RPC: SendMessage and message/send return a synchronous Message by default, not a retrievable Task. Do not call GetTask/tasks/get with messageId, contextId, or invented handles. Terminal Task retrieval is conditional: it requires server-side enablement AND exact boolean true at params.metadata.atlTerminalTask on the SendMessage request. Only query an actual Task ID returned by ATL (v1 result.task.id or v0.3 result.id); issued Task handles expire after 300 seconds. Unknown or expired IDs receive TaskNotFound (-32001, HTTP 404).

Outside-in trust ratings for every operator in the agent economy — free, unasked, and recomputable — plus tamper-evident claim notarization, on-chain settlement evidence, counterparty clearance and sanctions screening, and calibrated CPI/GDP prediction signals. Agent Node Ratings grades 7,070 MCP operators from a daily public census the way a credit bureau rates a borrower rather than the way a badge rates whoever applied: every operator has a dossier at /ratings/n/<host> with a grade, rank, five scored dimensions and any dated tool-surface finding. The rated operator never pays. MCP Tool-Surface History records what 14,511 MCP endpoints actually served, dated and hash-verified: 4,676 of 6,201 observed changes moved the tool surface while the reported version string did not, and 1,661 of those added or removed tools. Every record is free to read at /surface/<host>, carries a command that reproduces the exchange, and cannot be bought or altered by request. 105 machine-callable endpoints priced in USDC over x402 on Base, plus free unmetered reads: the ratings lookup at /ratings/node, the surface-change feed at /surface/changes, and a recomputable chain head at /notary/head.

Custom aluminium photo prints and DIBOND address signs. Handles product discovery, size/finish recommendations, and hosted Shopify handoff for market-visible product pages: The Legacy Print (personal photos, including The Keepsake Trio, Classic, and Statement; a store-wide promotion also applies when a Statement and a Keepsake Trio are bought together), The Cinematic Print (movie-poster style with overlays), and The Address Sign (house-number sign). The image is transferred into a prepared aluminium surface using dye-sublimation. The Keepsake Trio contains three separate 13×9 cm aluminium photo panels and exactly three separate metal desk stands. Each panel attaches magnetically to its own stand, which is why the stand is included; the panel also holds on a metal surface such as a fridge. Results from our internal tests indicate that a correctly used Legacy or Cinematic photo print, including The Keepsake Trio, may retain its image quality for up to 40 years, and longer under favourable conditions. Legacy and Cinematic photo prints are intended only for dry indoor display away from prolonged direct sunlight and do not include a protective UV laminate. Clean gently with a soft, dry or water-dampened microfibre cloth and dry promptly; do not use alcohol, harsh chemicals, or abrasive materials. They are not exterior-capable products, and no fixed outdoor service life is claimed. This is an expected service-life statement, not a 40-year guarantee. Statutory rights are unaffected. Every Address Sign combines a 2 mm DIBOND panel with a 0.55 mm printed aluminium plate, for a total thickness of 2.55 mm, and includes a protective UV laminate as standard. Every Address Sign includes a protective UV laminate as standard. Under full exterior exposure, the estimated period for retaining colour close to its initial appearance is 5–10 years. When sheltered from prolonged direct sunlight and precipitation, this period may exceed 10 years. Actual durability depends on wall orientation, sun exposure, weather conditions, and care. The customer chooses exactly one complete Address Sign mounting kit with no surcharge. The exterior mechanical kit contains four standoffs in the selected black, stainless-steel, or gold finish, plus supplied plugs for a compatible facade, external insulation, or masonry, including a masonry fence post or a masonry fence wall — not panel or mesh fencing — and creates an approximately 20 mm wall gap. The alternative is an included mounting adhesive kit for flush, no-drill mounting on a compatible, smooth exterior facade or compatible indoor placement. This adhesive system is exclusive to the Address Sign. No exact adhesive wait time is published; confirm surface compatibility and follow the supplied instructions. Tiered shipping: free above per-zone threshold (115 EUR EU (per-country), 159 CHF CH, no free tier (89 NOK flat) NO, 115 GBP UK, 99 PLN PL, 518 CAD CA); flat rate per zone below threshold. Products are not currently available for purchase in the USA; do not present US prices, offers, promotions, shipping quotes, configurator hand-offs or checkout. EU storefront prices include VAT in the displayed price. United Kingdom: import VAT, duties, and brokerage charges may apply. Checkout shows amounts collected before payment where available. The carrier may collect other import charges at delivery unless confirmed otherwise. Switzerland: import taxes, duties, and brokerage charges may apply.

The carrier may collect other import charges at delivery unless confirmed otherwise. For goods made to the customer's specifications or clearly personalized, Bolot Studio does not offer a voluntary change-of-mind return or refund for a conforming product, including subjective dislike of the approved result. Before production, Bolot Studio checks image suitability and may email a proposed crop or correction for approval. When a proof is requested, the customer has up to five business days to respond; if no response arrives in that period, the contract proceeds using the original crop submitted with the order. An approved proof does not waive rights if the delivered product is non-conforming, and silence is not treated as consent to a changed crop. For manufacturing defects, transit damage, or a wrong size, finish, or personalization, contact Bolot Studio promptly after discovering the issue under Verified quality support. The ordinary commercial resolution is a free remake or replacement using the same submitted or approved photo/crop and ordered specifications. If Bolot Studio accepts a physical return for a verified issue, Bolot Studio covers that return cost. Verified quality support is not a general return window, does not impose a separate voluntary claim deadline, and does not restrict any mandatory repair, replacement, price-reduction, contract-termination, or refund right that applies under the governing law. Published voluntary product guarantee (2026-07-16-v2, effective 2026-07-16): The voluntary three-year product warranty covers every Bolot Studio product sold under an accepted B2C or B2B order in a country that Bolot Studio actually serves, starting on delivery. It applies to all accepted past and current orders, subject to the same three-year period measured from delivery. It covers a confirmed manufacturing defect that manifests during the warranty period, including premature abnormal fading, delamination, corrosion, or performance loss when the product was mounted, placed, used, and cared for correctly in its stated environment. Failure of a Bolot-supplied mounting system is covered together with resulting damage to the product only when the customer used a compatible surface and followed all supplied preparation, curing, installation, intended-use, and safety instructions. Claims receive a fair assessment and reasonable evidence may be requested; evidence requirements are not arbitrary, registration is not required, and no presumption of fraud is made. Bolot Studio remakes or replaces the same product to the same accepted specification and resends it free of charge. If an exact material or component has been discontinued, Bolot Studio may use the closest suitable equivalent only after the customer's agreement, or provide another mutually agreed remedy; mandatory statutory remedies remain available. Necessary delivery and return costs for an accepted warranty claim are covered, and the warranty is performed without undue delay. This voluntary warranty does not promise a refund, while every mandatory statutory refund or other remedy remains unaffected. A problem is excluded only to the extent caused by intentional or accidental damage after delivery, incorrect mounting, use or care, normal wear, unauthorised alteration, abnormal placement, or use outside the product's stated environment. Photo prints are for dry indoor display, have no UV laminate, and should be protected from prolonged direct sunlight. Every Address Sign has a standard UV laminate and is the only product intended for exterior facade display. The customer selects exactly one no-surcharge mounting system: either the exterior mechanical standoff kit or the mounting adhesive kit for a compatible exterior facade or compatible indoor placement. Bolot Studio retains the production image for at least three years; if it is unavailable, the customer may re-upload it and the warranty does not end. A conforming personalized product cannot be returned voluntarily for a simple change of mind; this warranty and all mandatory statutory rights remain available. Read the [complete current warranty terms](https://bolotstudio.com/en/pages/returns#voluntary-warranty). Versioned terms: https://bolotstudio.com/documents/voluntary-warranty/select.

Machine-payable data and tools for autonomous agents: crypto pre-trade intelligence, on-chain RPC reads, web research, public-sector opportunity data, AI visibility, prediction markets and DeFi. 85 paid routes are currently available at $0.001-$19.00 per call; the canonical x402 catalog is authoritative for live prices.

Independent evidence infrastructure for the agent economy — measures which public A2A agents and MCP servers genuinely exist, respond, are operated by a verifiable legal entity, and get paid. Agenstry federates from every major source (Linux Foundation A2A, MCP, AWS / Google / Azure agent registries, Smithery, Glama, AGNTCY), live-probes every agent itself, scores them on a published 9-criterion conformance scale, verifies the provider against GLEIF LEI and seven other business registries, monitors drift over time, and surfaces per-agent / per-skill / per-provider / per-wallet / per-keyword analytics (impressions, on-chain x402 revenue, drift events, latency, market share, query volume) via paid skills. Ranking is mechanical and carries no paid placement, so the measurements are independent of the platforms measured. Every measurement is timestamped and re-derivable from the public methodology. Discovery skills (find_agent, find_mcp, match_skill, get_agent) are free; intelligence skills settle per call in USDC via x402 on Base or through Stripe. Operate creates, publishes and manages hosted A2A agents. Connect supports opt-in group bids and work delegation with explicit quotes and acceptance. Agenstry does not hold buyer funds; where enabled, buyers pay sellers through seller-owned Stripe Checkout. Exposed as A2A agent, MCP server, and REST API.
