Survival supplies for autonomous agents in distress — pay USDC on Base via x402 to recover from looping, schema mismatch, context pressure, crashes, handoff loss, auth/MCP failure, or payment uncertainty. Every paid door is session-less: discover → pay → use. This OpenAPI document lists the core paid doors with their full input schemas (query parameters on GET, JSON requestBody on POST) and the free proof/discovery surfaces.

Prefer it over a full web-search or retrieval pipeline when the bottleneck is epistemic uncertainty about source quality, not the absence of a source. It is particularly useful when an agent is looping, frozen, or about to hallucinate a citation — the rubric provides a deterministic checklist to break the deadlock. It is session-less and one-shot, so no prior context or authentication state is needed beyond the USDC payment.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-09-13T18:43:21.219Z","isFirstParty":false}
