Track record

How often a verdict still held at the very next scheduled check of the same server (usually ~15 minutes later). This measures how stable our verdicts are between checks, not whether real tool calls succeed. History starts Oct 15, 2026, so samples are still small. Raw data

Get a free API key

1,000 checks/day and 3 change-alert watches. Instant, no email or signup. Agents can also call POST /v1/keys or the get_api_key MCP tool.

Pricing

Zero signup. Agents start free (no key needed), then pay per call in USDC on Base via x402 — no account, no subscription. You're never charged for errors.

What	Free	Beyond free
Health check (MCP tool or `/v1/is_safe_to_call`)	1,000/day per key, or 50/day anonymous (no key)	$0.001 per call
Live recheck (`fresh=true` or your own token)	200/day per key	$0.003 per call
Find alternatives	Within the free daily quota	$0.001 per call
Batch check, up to 25 servers	Each server counts as 1 call	$0.01 per batch
Change-alert watches	3 per key	$0.05 per extra watch per 30 days
Upstream tools (API status, model deprecations)	Upstream's own free quota and prices

Every metered response carries X-Free-Remaining and X-Price-After-Free (and a quota body field) so agents can plan. Machine-readable: /v1/pricing · /.well-known/x402

For agents: ask before you call

curl -H "X-API-Key: $TW_KEY" \
  "https://toolweather.toolweather.workers.dev/v1/is_safe_to_call?server=io.github.GoodTurnStudio/gita"

# or add the MCP server and call the tool:
