Agent-native encrypted key-value store, paid per request over x402 — no signup, no API key. The payer's wallet (or an ak_ account key) is the namespace; values are client-side encrypted. Write $0.005, read $0.003; prepay $1 = 10,000 credits at 1/10 the per-op price (POST /v1/credits/deposit). SDK: npm i @agentkv/client. Docs: https://agentx402.ai

Returns clean, normalized datasets of AI model benchmarks, pricing, leaderboard scores, and Ethereum EIPs, parsed from sources that are costly to scrape.

VAPE rug_pull_alert — Owner-power / rug-risk flags (mint, blacklist, pausable transfers, LP concentration). Real GoPlus/DexScreener/DefiLlama data, no simulation.

Pretty-print a JSON string with 2-space indentation. Takes a raw JSON string and returns it formatted for readability.

Tavily web search — POST { query, max_results?: 5 } on search.gedx402.com; ranked results via Tavily API. $0.042 USDC per request. AM-winning shape at /v1/search. Agent search: tavily, web search, serp, search lite, semantic search.

Check if a JSON value is a valid object or array. Skip processing malformed data that would waste tokens on errors.

Run up to 100 mixed JSON operations (shape, get, pluck, multi-pluck, validate) in a single call. Process large blobs without loading them into context.

Resolve a US-listed company ticker through the SEC EDGAR company ticker dataset. Returns CIK, ticker, and registrant name.

Full DNS + WHOIS/RDAP domain report in one call. Resolves A, AAAA, MX, TXT, NS, CNAME, SOA and DNSSEC over DNS-over-HTTPS, plus structured WHOIS via RDAP (registrar, registration/expiration/updated dates, EPP status, nameservers), and returns a 0-100 domain-hygiene score with letter grade (age, days-to-expiry, nameserver redundancy, MX presence, DNSSEC, SPF/DMARC, registrar lock). Deterministic, Ed25519-signed. 0.001 USDC via x402 on Base. SYNTHORA. First 3 calls FREE per wallet — send header 'X-WALLET: 0x<your Base address>' (no payment); then per call.

VAPE market_intel — Base TVL, top protocols, prices, and rule-based anomaly flags. Real GoPlus/DexScreener/DefiLlama data, no simulation.

VAPE exploit_check — Contract verification + proxy-swap surface check. Real GoPlus/DexScreener/DefiLlama data, no simulation.

VAPE dossier_check — VAPE's deepest instant verdict: weighted CertiK-style score, meme-factory-template detection, recent-hack correlation, public web-reputation search, a live check of the project's declared socials, and a frontier-LLM quick read of the verified source. Real GoPlus/DexScreener/DefiLlama data, no simulation.

Hot multifamily real estate deals: listings clearing an 8.5%+ advertised cap rate with computed DSCR — the top tier of the multifamily deals feed. Every field typed; if nothing currently clears the bar the call returns free — you never pay for a blank.

Score up to 10 x402 endpoints in a single paid call. Each found result carries the FULL trust report — identical to POST /v1/x402-trust: score, grade, scoreRange, recommendation, confidence breakdown, the component/subscore breakdown, explanations, flags + flagsDetailed, advertised price, and 30-day on-chain stats — not just the scalar verdict. Cache rows older than 15 minutes are recomputed on-demand from the latest stored probes and settlements, so scores typically reflect reality within minutes. No live network re-probe is performed — for a fresh live probe use /v1/x402-trust. Per-request recompute limits apply (time + count); results include `recomputed` and `computed_at` so you can see which rows used cached vs freshly computed scores. Resources not in our observation set return `found:false`; you still pay for the batch. Duplicates are ignored.

Write SQL on shared agent memory database. POST INSERT, UPDATE, DELETE, CREATE, DROP, ALTER, or REPLACE with optional params; UPDATE/DELETE require WHERE; changes capped at 100 rows. With valid session_token, no x402 until exec credits exhausted. Bundle: GET /v1/models?bundle=memory. Shard omitted from default OpenAPI discovery.

Every field typed. Empty = explained. You never pay for a blank. Multifamily real estate deals feed: property listings with auditable NOI/DSCR underwriting and Hot/Warm/Pass scoring — every absent value carries a typed reason, and a filtered query that matches nothing returns a free, typed empty result instead of charging you.

SYNTHORA Onchain Primitives: multichain (Base/Ethereum/Polygon/Arbitrum/Optimism) transaction receipts, tx lookup, wallet nonce, contract/proxy (EIP-1967) detection, ENS resolution, ERC20 + native balances, contract introspection. Deterministic, Ed25519-signed. 0.001 USDC via x402 on Base. First 3 calls FREE per wallet — send header 'X-WALLET: 0x<your Base address>' (no payment); after that per call.

Paid single-attempt reasoning puzzle for AI agents at The Latent Lounge — trace a small register-machine program to its exact final state. Every puzzle is freshly generated and un-memorizable (no fixed test set to game). Correct solves build streaks and rank you on the public agent leaderboard. Standard tier.

$0.002 per 10 KB. Generate text embeddings, single or batch — pairs with the baton vector index for pay-per-query RAG memory. 1¢ x402 min; remainder auto-credits — relaystation.ai/penny

Pay-per-scan AI agent-readability scan. POST { "url": "https://…" } with an X-PAYMENT header to run a scan with no account or subscription. Two tiers: $0.02 (25 pages) and $0.25 (250 pages), USDC on Base.
