Image crop - Image cropagent402.tools

Crop an image to a pixel box, and/or rotate (90/180/270) and flip it - applied in that order. Send a public image URL or a base64 image. Returns the result as binary, or as a JSON data URI with dataUri:true. Deterministic.

Skill: SEC filings deep-dive - Skill sec filings deep diveagent402.tools

Bundled execution of the SEC filings deep-dive workflow - Pull the full EDGAR picture of a US public company in one workflow: recent filings, key financial time series, insider trades, and full-text search across the corpus. One x402 payment runs 7 underlying tools (edgar-company-lookup, edgar-filings, edgar-company-facts, edgar-company-concept, edgar-insider-trades, edgar-search, edgar-13f-holdings); partial-success per step.

EDGAR company lookup (ticker - - Edgar company lookupagent402.tools

Resolve a US stock ticker (e.g. AAPL) to its SEC CIK number, the primitive every other EDGAR call needs. Returns CIK in both zero-padded (0000320193) and integer form, plus the registered company name. Backed by SEC's company_tickers.json (public domain). ?ticker=AAPL

Search World Bank indicators - World bank searchagent402.tools

Search the World Bank indicator catalog (1,400+ indicators across GDP, demographics, health, environment, education, etc.) by keyword. Returns indicator codes you can feed into /api/world-bank-indicator. ?q=inflation&rows=10

DNS lookup - Dns lookupagent402.tools

Resolve any DNS record type for a host: A, AAAA, MX, TXT, CNAME, NS, SOA, CAA, SRV, PTR. Returns the records plus a count. Built on Node's native resolver - no external API.

Email deliverability check - Email deliverabilityagent402.tools

End-to-end email-auth report for a domain: SPF + DMARC + DKIM (probes common selectors automatically) + MX records + score 0–100. The one call to make when 'why is our mail going to spam?' lands in your inbox.

All coin ids (paged) - Coins listagent402.tools

The complete list of tracked coins (~18k) as {id, symbol, name}, paged: `page` + `perPage` (1-500, default 250). `includePlatforms: true` adds each coin's contract address per platform; `platform` (e.g. base, solana, ethereum) keeps only coins with a contract there; `symbol` keeps one ticker (exact, case-insensitive) across all its namesakes. For bulk id resolution, building a local symbol map, or enumerating every token on one chain; for a single lookup use coin-search.

B20 token info - B20 token infoagent402.tools

ERC-20 metadata plus B20 signals for any Base address: name, symbol, decimals, total supply, best-effort paused/cap, bytecode size, and whether the address carries the factory-issued 0xB200 prefix. Works on plain ERC-20s too (isB20 comes back false). ?address=0x…

Global DeFi market - Global defiagent402.tools

Global DeFi snapshot: DeFi market cap (USD), ETH market cap, DeFi-to-ETH ratio, 24h DeFi trading volume, DeFi dominance % of the whole crypto market, and the top DeFi coin with its share of DeFi. The DeFi companion of crypto-global (whole-market caps and BTC/ETH dominance) and of defi-tvl (locked value, a different measure). Cached in-process for 5 minutes.

Image thumbnail - Image thumbnailagent402.tools

Make a square thumbnail of an image - scales and center-crops to NxN (default 128). Send a base64 image and optional size. Returns the thumbnail. Deterministic, no network.

Text-to-speech (lite) - Tts liteagent402.tools

Convert text to speech with Kokoro-82M, ten times cheaper than /api/tts. Returns base64-encoded mp3 or pcm. The same request shape and the same ten OpenAI voice names as /api/tts, mapped to Kokoro's own voices; the voice is synthetic-sounding where the OpenAI tiers are not, which is the whole trade. Use this for high-volume narration, notifications and agent speech where the cost per call matters more than the timbre; use /api/tts or /api/tts-hd when it does not.

FRED series metadata - Fred series infoagent402.tools

Metadata for a FRED series: title, frequency, units, seasonal adjustment, observation date range, and popularity. Use before /api/fred-series to confirm the series fits your needs. ?seriesId=UNRATE This product uses the FRED(R) API but is not endorsed or certified by the Federal Reserve Bank of St. Louis.
