Get daily numerology number - Number of the Day API

post_numerology_daily

Read-only

Get the numerology Number of the Day, one of 1 to 9, 11, 22 or 33, with its full interpretation. The same seed returns the same number for the same date, so a user keeps one number all day, and the date defaults to today in UTC. The response returns the number, its type, a daily message and the archetype, keywords, strengths, challenges, career, relationships and spirituality reading in the language set by lang. Built for Number of the Day widgets, push notifications and daily content.

Example tool call

This call uses example arguments supplied in the tool’s input schema.

Input Schema

Name	Required	Description	Default
`date`	No	Date for the reading in YYYY-MM-DD format. Defaults to today (UTC). Useful for viewing past daily readings or pre-generating future ones.
`lang`	No	Response language (BCP 47). Supported: en, tr, de, es, hi, pt, fr, ru, zh-Hans, zh-Hant. Defaults to en. Coverage varies by domain, and a field with no translation in the requested language returns English.	en
`seed`	No	Optional seed for reproducible readings. Same seed + same date = same number every time. Pass any unique identifier (userId, email hash, session token) to give each user their own number for the day. Without a seed every caller receives the same shared number of the day.
`compact`	No	Set true for the same data in a compact shape: arrays of same-shaped objects arrive columnar as {"__cols":[names],"__rows":[[values]]}. Lossless, typically 40 to 52 percent fewer tokens.

Output Schema

Name	Required	Description	Default
`date`	Yes
`seed`	Yes
`type`	Yes
`number`	Yes
`meaning`	Yes
`dailyMessage`	Yes

A3.8/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true and destructiveHint=false, so safety is covered; the description then adds real behavioral context: determinism (same seed + same date = same number), all-day stability of the number, UTC defaulting for the date, and the shape of the returned reading. It does not cover rate limits or error behavior, but for a read-only lookup this is well above the annotation baseline.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The core capability and defaulting behavior are front-loaded in the first two sentences with little waste. The closing line about widgets and push notifications is closer to marketing framing than operational guidance, but it is short and does hint at intended use.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, annotations cover the safety profile, and all parameters are described in the schema; the description fills in determinism, defaulting and per-user vs shared behavior. Nothing an agent needs in order to call this correctly appears to be missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so all four parameters are already documented, including seed semantics and the language fallback to English. The description reinforces the seed/date determinism and the language-driven reading, but adds no syntax or format detail beyond what the schema already supplies, which is the baseline-3 case.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ("Get the numerology Number of the Day") plus its value domain (1-9, 11, 22, 33) and payload (full interpretation), which is concrete enough to distinguish it from most siblings. It never names or contrasts a sibling such as post_numerology_personal_day, so differentiation relies on the agent knowing what a "Number of the Day" is.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

"Built for Number of the Day widgets, push notifications and daily content" plus the seed discussion implies the intended contexts and the shared-vs-personalized modes. However, there is no explicit when-not guidance and no alternative tool is ever named, so routing between this and the many sibling numerology endpoints is left to inference.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
