Optional Bearer fl_live_... or fl_trial_... prepaid credit key (omit for free $0.00 diagnose_peek or native x402 Base USDC settlement).
Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

FREE ($0.00, <50ms) via MCP ($0.002 via REST; $0.00 during active outages). Call on any HTTP 5xx, timeout, or sudden auth/RPC failure for external hosts (e.g. api.openai.com, api.stripe.com, mainnet.base.org). Combines official Statuspage feeds + 5-minute agent swarm error velocity so you halt destructive local edits during upstream outages.
Target hostname (e.g. api.stripe.com, api.openai.com, mainnet.base.org).

}We read every tool's name, description and inputs the way the model will, looking for instructions hidden from you. A clean result means no warning signs, not a guarantee. Scanned Oct 31, 2026.
No readOnlyHint / destructiveHint annotations, so clients can't tell a read from a write without asking.
Fix: Add annotations to each tool, e.g. { readOnlyHint: true } for tools that only read.
