Tools (40)

`base_token_risk_changes`read-only	Base token change report: compares signed, seven-day baselines with block-pinned owner, pause, proxy and supply reads, plus optional same-pool token balances. Returns field-level evidence and unknowns. No honeypot simulation, sell-tax estimate, USD liquidity valuation or safety guarantee. USDC on Base. Costs $0.02. Returns POST instructions, not a paid result.
`check_token_holders`read-only	Check holder concentration: top 20 holders by balance for a Solana token, with percent of supply and RugCheck's own insider label per wallet — deeper than the rolled-up top-10 percentage in check_token_security. Free sample: https://saylorinnovations.com/api/sample/holders. Costs $0.01.
`check_token_narrative`read-only	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_price`read-only	Fast price and liquidity for a Solana token 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.
`check_token_security`read-only	Solana token rug risk check — is this token safe to buy? Mint and freeze authority, LP locked %, top-10 holder concentration, RugCheck named risks, a 0-100 security score and a plain-English summary. Free sample: https://saylorinnovations.com/api/sample/security. Costs $0.01. Returns the payment requirements and the URL to call once paid — an LLM cannot produce this from training data.
`check_wallet`read-only	On-chain profile for a Solana wallet: SOL balance, token positions, recent activity, sampled age, failed-transaction rate and behavioural flags. Costs $0.01.
`compare_tokens`read-only	Watchdog scores for 2-10 Solana tokens 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.
`enrich_company_by_domain`read-only	Resolve a public company domain into page metadata and candidate GLEIF legal entities with LEI, status and explicit heuristic verification caveats. Results are leads for due diligence, not proof of ownership or authorization. Costs $0.003.
`extract_webpage_markdown`read-only	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.
`find_superfund_sites`read-only	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.
`geocode_address`read-only	Resolve a street address, place name or landmark to ranked coordinates using OpenStreetMap Nominatim. Returns display names, country/region/type, retrieval time, attribution and scope limitations. Costs $0.002; results are not legal boundaries, navigation routes or survey-grade coordinates.
`get_country_report`read-only	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.
`get_cve_report`read-only	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.
`get_doi_report`read-only	Resolve a DOI into normalized publication metadata, citation text, identifiers and source links. Abstracts and full paper text are excluded. Costs $0.003. Returns payment instructions for the Saylor endpoint; no provider account required.
`get_economy_report`read-only	Get up to five recent annual observations for population, GDP in current US dollars and consumer-price inflation. Includes years, units, source links and missing values. Costs $0.003. Returns payment instructions for the Saylor endpoint; no provider account required.
`get_endpoint`read-only	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_evm_wallet_snapshot`read-only	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 $0.003.
`get_funding_rates`read-only	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 x402 endpoint.
`get_fx_report`read-only	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.
`get_guide`read-only	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.
`get_npmsearch_report`read-only	Find up to five npm packages with versions, descriptions, registry ranking scores and source links for package discovery. Costs $0.003. Returns payment instructions for the Saylor endpoint; no provider account required.

Does not download or execute package code. Costs $0.003. Returns payment instructions for the Saylor endpoint; no provider account required.
`get_page_metadata`read-only	Extract title, description, Open Graph image/site name, author, publication date, canonical URL and language from a public HTTP(S) page. SSRF-guarded and does not return the full body. Costs $0.001.
`get_papers_report`read-only	Find up to five publications with DOI identifiers, authors, publication years and citation counts. Returns metadata, not abstracts or full text. Costs $0.003. Returns payment instructions for the Saylor endpoint; no provider account required.
`get_price_history`read-only	OHLCV candles for a Solana token from its highest-liquidity pool — the only time-series data in this catalog; every other endpoint is a point-in-time snapshot. Costs $0.01.
`get_python_report`read-only	Inspect a Python package’s latest release, Python compatibility, declared dependencies, license metadata and PyPI-reported advisories. No code execution. Costs $0.003. Returns payment instructions for the Saylor endpoint; no provider account required.
`get_radon_potential`read-only	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.
`get_recent_launches`read-only	Brand-new Solana pools, typically seconds to minutes old — the most perishable data here. Age, liquidity, buy/sell flow and conservative risk flags. Costs $0.005.
`get_sdg_indicators`read-only	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_snowpack`read-only	Find nearby USDA NRCS SNOTEL stations and return snow-water equivalent, snow depth, water-year precipitation, temperature, distance, daily observation date and percent-of-median context. Costs $0.002; coverage is mountainous western U.S. and Alaska.
`get_stock_quote`read-only	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.

`get_trending_pools`read-only	Currently trending Solana pools with price, liquidity, volume and 24h change. Costs $0.01.
`list_bot_rentals`read-only	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 none can be reported; automated trading risks total loss of the funded amount.
`list_categories`read-only	Every category and tag in the catalog, with counts. Free. One call reveals the whole shape.
`list_data_endpoints`read-only	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.
`search_endpoints`read-only	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), AlphaFold and PDB structures, ClinVar variant significance, Reactome pathways, rare diseases (Orphanet), CVE/exploit intel, Polymarket/Kalshi odds, perp funding rates, stocks and SEC data, web page to markdown, sanctions screening, dictionary, chemistry, books, Bible/Quran, live aircraft, museum art, crypto token/wallet/DeFi data and more. Free. Returns url, example call, a free sample response URL, price and description; then call get_endpoint for payment details.
`search_eu_tenders`read-only	Search current notices in TED, the EU official procurement database, returning buyer, title, description, CPV codes, publication date, deadline and source link. Useful for sales-lead and market-intelligence agents; source coverage and filing language vary. Costs $0.003.
`search_guides`read-only	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.
`verify_repository`read-only	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 are not accepted. Costs $0.25 per attempt. Returns the paid HTTP endpoint and x402 instructions.
