Documentation Agent HTTPGenerate chart tool

Generate chart tool

POST/agent/v1/tools/generate-chartAgent HTTPFrom Free

Generate a bodygraph chart through an agent-safe interface.

Returns a versioned envelope with quota metadata. Creator supports core detail and Startup adds full detail. Valid execution that reaches calculation uses exactly one unit; pre-calculation validation and access failures use zero.

Authentication

Use Authorization: Bearer YOUR_API_KEY or X-Api-Key. Query-key authentication is deprecated compatibility behavior on supported REST routes and is rejected on Agent HTTP and MCP surfaces. Never put credentials in URLs, request bodies, or browser code.

Parameters

Name	In	Required	Description
`Idempotency-Key`	header	No	Strongly recommended stable 8–160 character key for consuming operations. Reuse it only when retrying the same request; without it, the API cannot deduplicate a lost-response retry. `hdai-example-19900515`
`Authorization`	header	Yes	Bearer API key. X-Api-Key is also supported. `Bearer YOUR_API_KEY`
`birthDateTime`	body	Yes	Birth date and local wall clock time, with no Z and no UTC offset. `1990-05-15T14:30:00`
`timezone`	body	Yes	IANA timezone. `America/New_York`
`detailLevel`	body	No	core or full; full requires Startup. `core`

Birth times are local wall clock times.
Send the birth date and time exactly as it read on the clock where the person was born, with no Z and no UTC offset. Give the zone separately as an IANA identifier. Date=1990-05-15T14:30:00 with Timezone=America/New_York means half past two in the afternoon in New York.

Deprecated: Values ending in Z or a numeric offset are deprecated. They are still accepted for now: the API reads them as UTC and calculates from that, and the response carries Deprecation: true along with a Warning header naming this rule. They will stop being accepted, and the date will be announced in advance. Read the full rule.

Quota effect

A valid authorized execution uses exactly 1 calculation unit immediately before the calculation provider is reached. Invalid input, unresolved references, unsupported detail levels, and denied tiers use 0 units.

Errors

Expect 400 for invalid input, 401 for a missing or malformed key, 403 when the active plan does not include this operation, and 429 when the monthly allowance is exhausted.
