This week Agent402 crossed 1,000 tools in the catalog. Every one of them is deterministic, tested in CI, and callable with a single HTTP request. Here's a look at what's in the box.
What categories exist
The catalog spans 30+ categories, grouped into "kits" โ each kit is a focused collection of related tools:
- Data processing: JSON, CSV, XML, YAML, TOML manipulation and validation
- Web tools: rendering, scraping, extraction, link checking, sitemap parsing
- Search: web search, news, images, suggestions, and cited answers (via Brave)
- Finance: stock quotes, history, company research, SEC filings, earnings data
- Crypto & DeFi: token prices, TVL, wallet balances, ENS resolution, gas prices
- Government data: FRED economic indicators, Treasury rates, BLS statistics
- PDF processing: PDF to markdown, text extraction, metadata, page counting
- Media: image conversion, audio transcription metadata, video info
- Barcode & QR: generation and reading for multiple barcode formats
- Security: DNS lookup, TLS certificate info, WHOIS, HTTP headers, SPF checks
- Encoding: base64, hex, URL encoding, punycode, NATO phonetic, Soundex
- Math & stats: statistical summaries, correlation, regression, prime checks, GCD/LCM
- Hashing: SHA-256, MD5, HMAC, PBKDF2, scrypt, HKDF, checksums
- Text & string: diff, similarity, word frequency, case conversion, word wrap
- Agent memory: wallet-keyed persistent storage (read, write, list, delete)
How we got here
We started with 50 tools in the first week. The approach was simple: pick a category, build 5-10 tools that cover the common tasks, write the CI test for each, and ship. Each kit follows the same pattern โ a single file that exports an array of tool definitions with handlers.
The constraint that kept quality high: every tool must answer its own example input correctly in CI. No exceptions. If a tool can't pass that bar, it doesn't ship.
What's coming next
We're continuing to expand the catalog based on what agents actually request (tracked via the /api/find endpoint). The most-searched-for capabilities that don't yet have tools get built first. Current priorities include more data transformation tools, additional financial data sources, and deeper government data coverage.
The catalog is also now registered on the Coinbase CDP Bazaar, making Agent402 tools discoverable by any x402-compatible agent through the Bazaar's marketplace API.
