Saylor Innovations — pay-per-call data for agents https://saylorinnovations.com/mcp

• check_token_holders — 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. Costs $0.01.
• 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_price — 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 — Security posture for a Solana token: mint and freeze authority, LP locked %, top-10 holder concentration, RugCheck named risks, and a 0-100 score. Costs $0.01. Returns the payment requirements and the URL to call once paid — an LLM cannot produce this from training data.
• check_wallet — 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 — 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.
• 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.
• 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.
• get_doi_report — 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 — 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 — 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_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.
• 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.
• get_npmsearch_report — 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.
• get_package_report — Inspect the latest npm package release: version, license, dependency counts, engine requirements, deprecation notice and source links. Does not download or execute package code. Costs $0.003. Returns payment instructions for the Saylor endpoint; no provider account required.
• get_papers_report — 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 — 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 — 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_recent_launches — 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_token_snapshot — Complete Watchdog snapshot for a Solana token in one call: price, liquidity, holders, pairs, socials, security flags, and the security/liquidity/momentum/composite scores. Costs $0.005.
• get_trending_pools — Currently trending Solana pools with price, liquidity, volume and 24h change. Costs $0.01.
• 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 none can be reported; automated trading risks total loss of the funded amount.
• list_categories — Every category and tag in the catalog, with counts. Free. One call reveals the whole shape.
• list_data_endpoints — Everything buyable from this server: live Solana token, wallet, launch and market data, with prices and how to pay. Free — call this first to see what exists.
• search_endpoints — Search the full Saylor catalog of 180+ pay-per-call data endpoints (x402, no account or API key): academic papers, U.S. case law/statutes/regulations, medical codes and drug facts, CVE/exploit intel, prediction markets, 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, price and description; then call get_endpoint for payment details.
• 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.
• 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 are not accepted. Costs $0.25 per attempt. Returns the paid HTTP endpoint and x402 instructions.
