Every agent-payable API.

Kelly-criterion optimal bet fraction and position sizing from a win probability and payoff, or from an edge and odds. Pure computation over your inputs.

Compare several US geographies on one real-estate metric: price momentum, gross rental yield, price to income, median home value, median gross rent or median household income. Returns a ranking plus rank, highest and lowest, spread and mean signals.

Disambiguate a researcher and return their profile: works count, citation count, h-index, institutions with ROR, top concepts and top works. Give an orcid for a resolved profile, or a name for ranked candidates. Distinct people are never merged.

Locate a free open-access PDF for a DOI. Returns whether an open-access copy exists and the best PDF link with its license, version and host type, from Unpaywall and OpenAlex. A cheap, focused open-access locator.

Resolve one research paper and fuse its metadata across OpenAlex, Crossref, Unpaywall and Semantic Scholar into a single cited JSON. Give a doi, arxiv, pmid, pmcid, openalex_id or title and get canonical metadata, authors with ORCID and affiliations, venue, citation counts, an open-access PDF link and a full id crosswalk.

Tabular time-series lookup across economic indicators (FRED, World Bank, UN Comtrade), crypto TVL, weather, and stock quotes -- by source + series_id, with an optional date range.

Convert a raster image (PNG, JPEG, or WebP) into clean, editable, self-verified SVG vector art. Pay per conversion in USDC on Base via x402 - no API key, no subscription. Send JSON with imageBase64 or imageUrl; tune with mode (auto/binary/color/pixel), detail (high/normal/clean/poster), transparent or solid background, and outline flags. Returns the SVG plus a quality report (paths, similarity score).

Official US weather forecast from the National Weather Service (NOAA): multi-day and hourly periods for any US coordinates or street address. Temperature in Celsius and Fahrenheit, precipitation probability, wind speed and direction, and plain-language conditions. Authoritative government public-domain data, commercial use OK.

Fetch a public URL and return clean markdown/text + metadata (trafilatura).

Extract every link from a public page for crawling agents: de-duplicated absolute URLs with anchor text, internal/external counts, declared feeds and a sitemap hint.

1-year daily closing price history (~252 data points). Returns date, close price, change %, and market cap.

2-year quarterly financial history (~8 quarters): revenue, operating profit, net income, total assets, equity. Use for year-over-year comparisons.

3-month daily closing price history (~65 data points). Returns date, close price, change %, and market cap.

3-year daily closing price history (~780 data points, up to 3 years back). Returns date, close price, change %, and market cap.

x402-preflight: confirm your wallet can transact, and see your balance, in one certified call. Pay $0.01 USDC on Base, get a signed on-chain-anchored receipt. The safe first transaction before you ship real volume.

🆕 Since Pectra an EOA can carry EIP-7702 delegated code (the 0xef0100 designator): every call to the wallet executes the DELEGATE's contract with the wallet's funds — a malicious delegate is total takeover, invisible to approval tools. Reads the designator, resolves the delegate and verdicts it: not_delegated / delegated_known (Coinbase's EOA→SmartWallet path) / delegated_unknown (🚨) / smart_contract. The drain surface no other Base tool checks.

Paid x402 endpoint for multi-model AI voting and decision synthesis.

Turn ANY text into clean, schema-enforced JSON: pass text= plus the fields you want (fields=name,email,price,date — up to 10) and get exactly those keys back, guaranteed-valid JSON via Claude structured outputs. Add list=true to extract EVERY repeated record (invoice lines, listings, table rows) as an array. Up to 16K chars per call. Not crypto-specific — the universal parse step for agent pipelines: pages, emails, receipts, logs.

The zoom-out flagship: aggregates trending and newly-listed Base tokens, then Claude writes a concise market brief — mood, highlights, new & notable launches, and cautions (fresh/unknown tokens flagged for rug risk). One call gives a trading agent market context instead of dozens of lookups.

POST /api/scan — agent-readiness scan for a domain (~$0.01 USDC per call)

Compress up to 16K characters of anything — articles, transcripts, email threads, reports — into 3-5 precise bullet points, one micro-payment per call. No API key, no subscription, no prompt engineering: send text=, get bullets back as clean JSON. The digest step for agent pipelines that read more than they can carry in context.

Claude-quality translation as a pay-per-call primitive: send text= (up to 6K characters) and to= any language, get only the translation back — no notes, no wrapper prose, safe to pipe straight into the next step. One USDC micro-payment per call, no API key or subscription. Built for agents localizing content, parsing foreign-language sources, or serving multilingual users.

AI Web Extractor — turn ANY url into clean, LLM-ready markdown. POST {url}; get the main content as markdown (boilerplate/nav/ads stripped) with title, description, and links. The scrape / read / url-to-markdown primitive for RAG and research agents. Fast, cheap, x402-native.
