## FAQ

### What does the Planetary Positions API return?

Calculate accurate tropical zodiac positions for all 14 celestial bodies (the 10 classical planets Sun through Pluto, the lunar nodes, Chiron, and Black Moon Lilith) for any date, time, and location. Every response is structured JSON with documented fields, not free text, so you map it straight into your product.

### How do I authenticate with the Planetary Positions API?

Pass your key in the X-API-Key header on every request. Keys are delivered instantly at checkout with no approval queue. Use a secret sk key server side, or mint a publishable pk key locked to your origins for browser and no-code use.

### Does the Planetary Positions API support multiple languages?

Yes. Append the lang query parameter to any endpoint for responses in English, German, Spanish, French, Hindi, Portuguese, Russian and Turkish. The translated payload includes the full interpretation text, not just field labels.

### Do I need coordinates to call the Planetary Positions API?

No. Call GET /location/search with a city name first, then pass latitude, longitude, and timezone from the first result into the request. Never ask users to type coordinates. Timezone accepts a decimal offset or an IANA name.

### Is the Planetary Positions API available over Remote MCP for AI agents?

Yes. Every endpoint is exposed as a callable tool on the Remote MCP server at https://roxyapi.com/mcp/astrology over Streamable HTTP, so Claude, ChatGPT, Cursor, and any MCP client auto-discover it with no local setup or Docker.

### How is the Planetary Positions API billed?

Flat pricing: 1 request equals 1 quota unit, REST and MCP identical, with no credit weighting or per-token markup. Every plan includes all 12 domains, so the Planetary Positions API is included at no extra cost.

### What lang values does the Planetary Positions API accept?

The lang parameter accepts en, tr, de, es, hi, pt, fr, ru. Case-insensitive where it is a path value.
