DripMetricsAI (api description at https://dripmetrics.ai/) provides on-demand market microstructure and risk metrics for agents and developers.

Discovery examples use the latest 30m window.

DNS A record lookup — resolve any hostname or domain to its IPv4 addresses, returned as a clean JSON list. For host resolution, connectivity and uptime checks, IP-reputation enrichment and infrastructure mapping.

Fetch data rows from a specific e-Stat statistical table (by id from estat.search), with all category codes (region, item, time period, etc.) pre-resolved to their human-readable Japanese labels in a single call — normally requires a separate metadata lookup and manual code-matching against the raw e-Stat API. Source: e-Stat API, government standard terms of use (CC BY-compatible, commercial use permitted). Factual statistical data only; not investment or economic advice.

Convert structured data between csv, json, and yaml. Body: {data, from, to}. Returns the converted result. Use for data wrangling and format normalization.

Coordinate multiple agents through one shared workspace: $0.25 for 7 days and 1000 operations, all free after this one payment. BARRIER — collect results from N sub-agents: each gets its own arrive URL; when the last one reports, ONE webhook fires with everything collected; a missed deadline sends a partial event naming who's missing. LOCK — exactly one agent performs a critical step: others get 409 naming the holder, and leases expire on their own, so a crashed agent never blocks the rest.

Find bugs, explain errors, suggest fixes.

The cheap company-intelligence read sales, research, and qualification agents make.
