Prefix Visibility API
Reports the propagation of a prefix as the fraction of RIS observers that see it, separately for IPv4 and IPv6, because the absolute peer count moves with the size of the measurement network and is not comparable across time or between prefixes. The share is graded against stated thresholds, and — this is the part that makes the number mean something — compared against the other prefixes announced by the same origin AS.

Preflight
Call before publishing a claim that cites EU law. Checks that the cited instrument exists in our pinned corpus, that the cited article exists within it, and whether your quoted text actually appears in that article. Covers the AI Act, GDPR, NIS2, DORA and the Cyber Resilience Act. Returns the official article text with a EUR-Lex link. Citation verification only: it never gives legal advice or classifies systems.
preflight402.com-$0.10listed
Preflight
Call before signing or broadcasting a Bitcoin transaction. Decodes a raw transaction hex or a PSBT and returns inputs, outputs, script types, addresses, vsize, fee rate when derivable, and objective signals such as RBF, dust outputs, non-standard sighash flags and unsigned inputs. Parses only the bytes you send: no network access. Describes the transaction; never advises whether to sign it.
preflight402.com-$0.10listed
Preflight
Call before signing an Ethereum or Base transaction or calldata. Decodes raw transaction bytes or contract calldata against standard interfaces (ERC-20, ERC-721, ERC-1155, WETH, EIP-2612 Permit and Permit2) in memory. Returns the decoded method signature, typed parameters, value in wei and standard specification links. Mechanical byte decoding only: never simulates state or advises whether to sign.
preflight402.com-$0.10listed
Preflight
Call before signing a Bitcoin transaction when you need chain context for its inputs: whether each prevout exists, whether it is already spent, its value in sats and its confirmations. Resolves up to 10 inputs against a public explorer at about one request per second, so a full batch can take over 20 seconds; figures reflect chain state at checked_at. Describes on-chain facts with source links; never advises whether to sign.
preflight402.com-$0.10listed
Preflight
Call when you need to know which articles of the EU AI Act mention a given obligation for a given role (provider, deployer, importer, distributor, authorised representative). Returns the matching articles with headings, excerpts and EUR-Lex links from a pinned corpus version. Retrieval over the official text: it does not classify your system or assess compliance.
preflight402.com-$0.10listed
Preflight
Call before acting on CVE identifiers produced by a model. Returns whether each CVE record exists and its state (published or rejected), with severity and the official CVE record link. Catches fabricated advisory references. Does not tell you whether to patch.
preflight402.com-$0.05listed
Preflight
Call before pinning or installing a specific package version in npm, PyPI or crates.io. Returns whether that exact version exists in the official registry, its publication timestamp, whether it is deprecated or yanked, its published artifact hashes, and whether an expected SRI/hex digest matches. Compares registry metadata only and never returns a safety verdict.

Preflight API
One-authority deterministic England taxi-private-hire licensing preflight for a supported authority. Use for applicant, driver, vehicle, or operator blocker checks, missing-input identification, and the next evidence-gated action before submission or onboarding. This tool does not compare authorities. Deterministic England taxi/private-hire licensing decision with official-source evidence and per-rule freshness guards. Pay only when the blocker check or comparison is decision-relevant. Not licensing-authority approval or legal advice.

Preflight Before Paying An X402 Service API
Preflight before paying an x402 service: is it working right now, and did it work the past 30 days? One live probe of the exact resource URL you intend to pay (status, latency, x402 validity, the payTo/price the service itself publishes in its 402, manifest presence) plus our own monitoring history of the host (30-day uptime, last check, recent changes such as payTo or price drift). Optionally verifies that the pay_to you intend to pay matches the live 402. Facts only — no scores.
