Run a routine
Starts a run of the active version (or `version`) with `input`, validated against the routine's `inputs` schema. Use `?wait=` for tool-call style use (an `ephemeral` run that finishes within the wait never touches the journal), `Accept: text/event-stream` to follow steps live, or `webhook`. Effect steps without a product meter of their own bill `routines.effect_step`; product steps bill their product's unit.

Starts a run of the active version (or `version`) with `input`, validated against the routine's `inputs`
schema. Use `?wait=` for tool-call style use (an `ephemeral` run that finishes within the wait never touches

meter of their own bill `routines.effect_step`; product steps bill their product's unit.
Authentication
Bearer Token (b3os_sk_ API key or b3os_pat_ token) API Key (cookie: __Host-b3os_session)
Path Parameters
routine
string
required
path
A routine ID (`rtn_…`) or name. Names are unique per project; `runs`, `hooks`, `validate` and `import` are
reserved and cannot be routine names.
Example:
"nightly-digest"Query Parameters
wait
integer
optional
query
Seconds to wait for the job to finish before responding, from 0 to 60. If it finishes in time the response
is `200` with the finished job; otherwise `202` with the job as it is, a `Location` to poll and
`Retry-After`. `0` (the default) returns immediately.
Header Parameters
Idempotency-Key
string
optional
header
A unique value (for example a UUID) that makes this request safe to retry. Scoped to your project for 24
hours: a retry with the same key, method, path and body returns the stored response with
`Idempotent-Replayed: true`, and only to the same API key. Reusing the key for a different request returns
`409 idempotency_key_conflict`.
Request Body
application/jsoninput
object
Validated against the routine's `inputs`; defaults from it are applied.
version
string | integer
Run this version instead of the active one (`ver_` ID or number).
One of:
Option 1string
Option 2integer
durability
string
Override the routine's default durability for this run.
Enum:
ephemeral, standard, strictwebhook
object
Where to deliver this job's events. Deliveries are `POST`s of a `WebhookEvent` signed with
`B3OS-Signature: t=<unix seconds>,v1=<hex HMAC-SHA256 of "<t>.<raw body>">` using the endpoint's secret
(`POST /v1/webhooks/secret`). Failed deliveries are retried with backoff for 24 hours. Delivery goes
through the egress guard, so private and loopback addresses are refused.

REQUIRED
An `https://` URL.
events
string[]
Event types to deliver. Defaults to the terminal events (`job.succeeded`, `job.failed`, `job.canceled`); `["*"]` delivers every event.

`A-Z a-z 0-9 _ . : -`; values are at most 500 characters. B3OS never interprets them.
