Behavioral Science API

Bearer-key JSON REST API on phoslabs.io. The provider-published OpenAPI 3.0.3 (verbatim in openapi/) declares seven operations — six metered POST tools (audit 0 credits, diagnose 10, fixCheckout 30, copy 20, pricing 25, detectBiases 8; 1 credit = EUR 0.01) and an anonymous GET /api/v1/tools (listTools) that returns the live inventory with prices and input fields. Keys are issued by POST /api/trial or by buying credits. Every response carries credits_remaining; errors are {"error": string}; no Idempotency-Key, no reversal path, rate limits unpublished. The provider README lists nine further tools the contract does not serve.
