# A schedule of perturbations drawn from graded randomness, to seal.

`POST /api/agents/run/pull_schedule`

## Request

- Base URL: `https://tomorrowlives.com`
- URL: `https://tomorrowlives.com/api/agents/run/pull_schedule`
- Auth: HTTP bearer

Draws a schedule of perturbations (tempo up or down, phase advance or delay, and catch trials where nothing changes) placed with a lead-in and random gaps; spec sets its trials, gaps and beat (pull_schema lists the keys). By default the randomness is 32 bytes of this server's operating-system randomness, graded hardware_seeded; seed draws from software instead (graded software, which a research run refuses); entropy_hex with grade brings your own bytes and says where they came from. research refuses software randomness. Returns the schedule and its text, which pull_seal seals. Nothing is kept here. Costs 1 unit.

## Request body

- object
  - `spec` object: The schedule specification written inline as JSON; pull_schema lists its keys.
  - `research` boolean: True to draw the schedule for a research run.
  - `entropy` 'os': The entropy source: os, the server's own.
  - `seed` integer: A whole number that makes the run reproducible: the same seed and inputs give the same answer.
  - `entropy_hex` string: Your own entropy as hex, in place of the server's, when you must bring the bytes yourself; grade then says where they came from.
  - `grade` 'true_random' | 'hardware_seeded' | 'physical_noise' | 'software': How the entropy you brought was produced, recorded with the schedule.

## Response `200`

The job's result and files

- Job
  - `job` string
  - `verb` string
  - `units` integer
  - `ms` integer
  - `result` unknown
  - `files` object[]
    - `name` string
    - `bytes` integer
    - `content_type` string
    - `url` string
    - `url_expires_at` string, date-time

## Other responses

- `400`: The input is not valid
- `401`: No valid API key
- `402`: A pass or a payment is needed: a queued render on the free plan, a unit pack on the free plan (pass_required), a card plan's past-due renewal, or, on the free plan, an owner who has not confirmed their email yet (owner_unconfirmed; a pass needs no confirmation); or a payment did not go through (payment_failed, payment_token_unusable), and nothing was charged
- `403`: The account is suspended, the paying card is not from the United States (region_not_supported), or the address named as its owner said it is not theirs and costed runs are paused until a new owner is named (owner_removed)
- `413`: The input or the output is over its cap; a job stopped by the output cap is not charged
- `422`: The engine refused the input, a limit of the service's refused it (error: video_limit or pull_limit) or stopped the job, or the content policy refused the input (error: content_policy)
- `429`: A limit was hit; reset_at says when it lifts (also in Retry-After)
- `503`: The engines are busy or not installed
- `504`: The job ran past its time and was stopped
