The Shop Window. REQUIRES ?url= on the paid request — a signed request without it is refused before the gate and no money moves. A signed JSON report — verdict (ready, not_ready, unreachable or refused), every check and advisory from the published on-page battery, the blind spots printed on the artifact, dated, its evidence hash bound into the purchase certificate's attests field — plus a stable report URL serving the record free forever. Instant; one GET of the HTML as serv…

Before your agent bills a customer: get the whole Factur-X file it sends and the customer reads - a PDF/A-3B embedding the EN 16931 CII XML, the hybrid invoice mandated by the French 2026-2027 reform. Post simple business JSON (parties, lines, VAT), get a file ready to send and archive: totals computed, inconsistent input refused field by field, the official rule set cleared and the embedded XML re-read byte for byte. vat_treatment writes the reverse charge or intra-Community exemption mention.

Paginated library list. Filter with ?kind= (video|audio|image|gif|asset|source|stock), ?source= (upload|generated|import-url|stock), ?tag= (exact tag) so a real library isn't an undifferentiated soup.

Income, balance sheet, and cash flow statements in one response.

Frontier chat on QWEN3 30B A3b FP8 (@cf/qwen/qwen3-30b-a3b-fp8). POST messages[] for reasoning-heavy agent workloads; dynamic token pricing. Hero: GET /heroes/frontier-llm. Tiers: /v1/chat/reasoning, /v1/chat/code, /v1/chat/agent, /v1/chat/70b.

Decode an off-chain SIGNATURE REQUEST before you sign it: EIP-712 typed data (eth_signTypedData_v4) or a plain personal_sign string. Turns the opaque request into a human-readable summary plus security risk flags for the drainer patterns wallets miss - gasless unlimited token approvals (EIP-2612 Permit, DAI permit, Uniswap Permit2) and asset-transferring marketplace orders (Seaport). Keyless, deterministic, zero network.

Fetch a verified contract's ABI and metadata by address, keylessly, from Sourcify. Returns the ABI plus a summarized list of function and event signatures, the contract name and compiler, and proxy detection (is_proxy + implementation address). Block explorers gate the ABI behind an API key; this does not. Chains: base, ethereum, arbitrum, optimism, polygon, bsc, avalanche. No API keys, no LLM, one x402 USDC micropayment per call.

Key annual fundamentals for a US ticker from SEC XBRL: revenue, net income, total assets and liabilities, stockholders equity, cash, basic EPS and shares outstanding, each with its fiscal period and source concept. Keyless, public-domain EDGAR. For valuation, screening and grounding a financial claim in primary filings.

Fleet-wide uptime statistics for every monitored endpoint: uptime percentage, average response time, and total check count over 1, 7 and 30 day windows (plus an optional custom window). Use it to get an at-a-glance reliability picture of a service fleet in one call.

Check one-to-one aliases against every typed pin; identifier mapping does not establish ownership, rights or authenticity for caller-supplied artifact and dataset provenance manifests. No source download, build reproduction, signature verification, proof of origin, causality or scientific validity. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.

Require exactly one satisfied declaration per requested precondition; absent, duplicate, unsatisfied or unknown checks cannot pass for public nonpersonal agent credential declarations. No DID resolution, live revocation lookup, signature verification, person identification, key custody or identity certification. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.

Compare closed export-field guarantees. Removing fields, changing types or weakening required/non-null promises breaks the declared reader; extra fields depend on its explicit strictness for public nonpersonal agent credential declarations. No DID resolution, live revocation lookup, signature verification, person identification, key custody or identity certification. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.

No source download, build reproduction, signature verification, proof of origin, causality or scientific validity. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.

Check parent existence and cycles within owner and subject frames. Declared links do not prove causal execution or delegation authority for public nonpersonal agent credential declarations. No DID resolution, live revocation lookup, signature verification, person identification, key custody or identity certification. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.

Bind record references to an exact owner/subject/revision/content/source frame; hash-shaped strings are declarations, not independently verified source bytes for caller-supplied artifact and dataset provenance manifests. No source download, build reproduction, signature verification, proof of origin, causality or scientific validity. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.

Separate record changes from shared-record reordering; inserting or deleting a record does not itself reorder surviving records for public nonpersonal agent credential declarations. No DID resolution, live revocation lookup, signature verification, person identification, key custody or identity certification. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.

Result retention: 24 hours; minimal receipt metadata: 90 days.

Check operand indices, repeated operands and references to caller-declared gate arities. Register indices are zero-based; instruction names alone do not establish an implemented gate. Caller-supplied public/synthetic nonpersonal metadata only. No quantum simulation, device/API access, execution, calibration measurement, scientific validation or claim of circuit equivalence. Input limit: 32 KiB. Result retention: 24 hours; minimal receipt metadata: 90 days.
