Behavioral Science API is one of 2 APIs that [Phos Labs](https://apis.io/providers/phoslabs-io/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Behavioral Science, Conversion Optimization, Pricing, and Copywriting. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, an API reference, a getting-started guide, authentication docs, and rate-limit docs.

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response carries credits_remaining; errors are {"error": string}; no Idempotency-Key, no reversal path, rate limits unpublished.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.
