• get_fx_report
  Get daily reference exchange rates per one unit of a base currency, with observation date and currency codes. Not executable trading quotes. ECB source data is also available free from ecb.europa.eu. Costs $0.003. Returns payment instructions for the Saylor endpoint; no provider account required.

• verify_repository
  Clone a public GitHub repository into a disposable Firecracker microVM, install dependencies, run one declared test, lint, or build script, and return structured logs plus the resolved commit. The service verifies execution, not semantic correctness; private repositories and arbitrary shell commands
• search_endpoints
  Search the full Saylor catalog of pay-per-call data endpoints (x402, no account or API key). Solana token rug risk and holder concentration, token prices on 25 chains, ERC-20 balances, academic papers, U.S. case law/statutes/regulations, medical and HCPCS codes, drug facts, protein function (UniProt
• get_endpoint
  Given an endpoint URL from search_endpoints (with its parameters filled in), returns the exact resource URL, price and x402 payment instructions. The agent then pays over HTTP and receives the data. Free.
• get_funding_rates
  Current perpetual-futures funding rates across Hyperliquid, Binance and Bybit observations, with venue intervals, annualized comparisons, open interest filters, spread/arbitrage signals, source provenance and explicit execution-risk warnings. Costs $0.002; returns payment instructions for the live x

• find_superfund_sites
  Find U.S. EPA National Priorities List sites near coordinates or a place, including identifiers, cleanup status, hazard-ranking score, dates, distance and source profiles. Costs $0.002; distances use site reference points and are not a property-safety determination.
• get_radon_potential
  Look up area-level geologic radon potential, index, province, geology and EPA screening guidance for a U.S. location. Costs $0.002; this is not a building measurement—any home can have high radon and should be tested.

  Return latest reported headline UN SDG indicators for a country, with indicator series, values, years, units, earliest comparison values, source provenance and disclosure that reporting years vary by indicator. Costs $0.003.
• get_evm_wallet_snapshot
  Read a Base, Ethereum, Arbitrum, Optimism, Polygon or BNB Chain wallet at the live chain head. Returns native balance, requested ERC-20 balances, token metadata and the block number used; this is a point-in-time read, not custody, valuation, proof of reserves or transaction authorization. Costs $0.0
• get_stock_quote
  Look up a stock, ETF or index quote with price, change, day and 52-week range, volume, exchange and market timestamp. Yahoo Finance with Nasdaq fallback; exchange delays can apply and unknown symbols are returned as free 404s. Costs $0.002.

• extract_webpage_markdown
  Fetch a public URL and extract the main content as clean Markdown with title, author, publication date, canonical URL, links and source metadata. SSRF-guarded, bounded and designed for agent research; private addresses, non-HTML files and error pages are refused before payment. Costs $0.005.
• list_data_endpoints
  Every currently buyable endpoint in the live x402 manifest, with its current description, price, supported payment networks and payment-discovery links. Free — call this first to see the complete catalog.
• check_token_security
  Token rug risk check on any chain — is this token safe to buy? Solana: mint and freeze authority, LP locked %, top-10 holder concentration, RugCheck risks. EVM chains: honeypot, tax, owner and contract checks read from the chain. Tron and Sui: scanner results. All chains: severity-ranked flags with
• check_token_price
  Fast price and liquidity for a token on any chain (Solana, EVM, Tron, Sui, TON and more); on Solana from two independent sources, with the spread between them reported — a wide spread is itself a signal. Costs $0.001, the cheapest endpoint here, built for polling.
• get_token_snapshot
  Complete Watchdog snapshot for a token on any chain in one call: price, liquidity, holders, pairs, socials, security flags, scores, a verdict, price-impact estimates and data coverage. Costs $0.005.
• get_coin_dossier
  Everything Watchdog can establish about one coin on any of 70+ chains in a single call: market and liquidity, the verdict, the chain's own token controls (who can mint, freeze, claw back, pause or upgrade it), creator and deployer history, verified source and owner-style functions, OFAC screening, q
• check_token_narrative
  Which meme/narrative category a token fits — ai, dog, cat, political, gaming, defi, infrastructure, frog, food, or memecoin — plus its socials. Costs $0.005.
• check_token_holders
  Holder concentration for a token on any chain: Solana top 20 with RugCheck insider labels; EVM, Tron and Sui top holders with contract, locked and burn labels, LP lock status, creator and owner share, OFAC screening and ranked flags — deeper than the rolled-up top-10 percentage in check_token_securi
• get_price_history
  OHLCV candles for a token on any chain from its deepest pool, plus change, drawdown, volatility and volume computed from the candles — the only time-series data in this catalog; every other endpoint is a point-in-time snapshot. Costs $0.01.
• compare_tokens
  Watchdog scores, verdicts and a ranking for 2-10 tokens on any chains side by side in one request. Priced per mint at $0.0015 — cheaper per mint than get_token_snapshot since the payload is lighter. Good for screening a watchlist in one call instead of one call per token.
• get_trending_pools
  Currently trending token pools on Solana (default) or any supported chain via chain, with price, liquidity, volume and 24h change. Costs $0.01.
• get_recent_launches
  Brand-new pools on Solana (default) or any supported chain via chain, typically seconds to minutes old — the most perishable data here. Age, liquidity, buy/sell flow and conservative risk flags. Costs $0.005.

  On-chain wallet profile on Solana, seven EVM chains read in parallel (Ethereum, Base, Arbitrum, Optimism, Polygon, BNB, Avalanche), Tron, Sui or TON: balances and valued holdings, account type including EIP-7702 delegation, activity, OFAC sanctions screening and ranked flags. Costs $0.01.
• search_guides
  Search Saylor Innovations technical guides (crypto safety, DNS/domains, Linux, IoT/hardware, mining, web scraping, content growth). Free — no payment. Returns metadata only, never bodies.
• get_guide
  Fetch a guide by id. Free guides return the full body immediately. Paid guides cost $0.01 in USDC/USDT/SOL on Solana or USDC on Base, Polygon or Arbitrum, via x402 — this returns the payment requirements rather than the body. Use the returned url with a PAYMENT-SIGNATURE header to complete payment.
• list_bot_rentals
  Trading bots available to rent for a fixed period, with prices and durations. The renter runs the bot themselves with their own exchange key or wallet — nothing is hosted and no credentials are sent to this server. Free to call. Note: no performance or profitability data exists for these bots, so no
• list_categories
  Every category and tag in the catalog, with counts. Free. One call reveals the whole shape.
