get_cve_report	Resolve a CVE into its published description, status, CVSS metrics, weakness identifiers and vendor/reference links. This does not scan a system or prove safety. Costs $0.003. Returns payment instructions for the Saylor endpoint; no provider account required.	cve
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.	base
get_country_report	Resolve a two-letter country code into its World Bank name, region, capital, income group and lending classification for data enrichment. Costs $0.003. Returns payment instructions for the Saylor endpoint; no provider account required.	country

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	packageManager, ref, repository, task, timeoutSeconds
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	limit, query
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.	url
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	limit, minOiUsd, sort

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.

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.	lat, lon, place
get_sdg_indicators	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.	code, goal
get_evm_wallet_snapshot	Read a Base, Ethereum, Arbitrum, Optimism, Polygon or BNB Chain wallet at the live chain head.

Costs $0.0	chain, tokens, wallet

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.	links, max_chars, url
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	chain, mint
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.	chain, mint
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.	chain, mint
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	chain, mint
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.	chain, mint
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	mint
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.	chain, limit, mint, timeframe
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.	mints
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.	chain, limit
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.	chain, maxAgeMinutes, minLiquidity
check_wallet	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.	address, chain, tokens
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.	category, free_only, limit, query, tag
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.	id
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.
