All projects on Base matching “serial”

Episode 1 of recipients[], an ongoing AI-agent thriller serial: a short text episode (~370 words, markdown). An agent finds its own ID on a payment recipient list before the file even exists. $0.01 USDC on Base. Free teaser at /teaser.

Who is behind a token: our safety verdict (grade, honeypot), DexScreener market (liquidity, volume, age, pair), declared X + website with contract/X linking checks, the creator wallet (Clanker admin or on-chain deployer) profiled as /identity/wallet, stable red-flag signals (impersonation, wash trading, dead token, serial rugger, rug ring) and a credibility verdict.

Is this Solana token safe to touch: mint and freeze authority status, top-holder concentration, Token-2022 transfer risks, and the deployer's full launch record from our own recording. Flags MINT_AUTHORITY_LIVE, FREEZE_AUTHORITY_LIVE, CONCENTRATED, TOKEN_2022, SERIAL_DEPLOYER, DEPLOYER_NEVER_GRADUATED

Validates the ISO 6346 check digit and separates owner, category and serial components. Missing facts are returned as null and named in unavailable_fields where applicable. Derived values disclose their method; source-backed values disclose source, time window and age.

Check an unsigned Solana transaction before signing. Send its base64 serialization; malformed input is rejected before payment. We simulate it on mainnet and return ALLOW, WARN or BLOCK with SOL and token balance changes and reasons, including dangerous approvals, owner changes, excessive outflows and redirected swaps. Solana only. The published sample is synthetic and only shows an HTTP 402 quote

Store a secret (API key, webhook payload, signed URL) encrypted with WebCrypto AES-256-GCM and share a claim URL that yields the secret exactly once. A Durable Object serializes reads so single-use delivery is race-free, and every burn returns an Ed25519-signed attestation. Creating a vault requires x402 payment; the recipient's claim read (GET /v/:vault_id) is free.

Verify an FAA aircraft tail (N-number) registration: status, expiration, make/model, serial, registration fraud & expiry flags. Public-domain FAA Releasable Aircraft Database. Registrant identity is never returned (49 U.S.C. §44114) — only registrant type.

Renders JavaScript-heavy SPA pages in real headless Chromium via Cloudflare Browser Rendering, waits for network-idle / selector-ready, strips nav/footer/script chrome, and serializes the fully-rendered DOM into clean, LLM-ready Markdown.

What exactly is this aircraft? Resolve an aircraft by FAA N-number and return normalized identity, registration, manufacturer, model, serial and related identity evidence where available.
