> Publish makes an Offer available for parties to accept.

Publish makes an [Offer](/business/nouns/offer) available for parties to accept.

## Inputs
| Input | Type | Required | Description |
| --- | --- | --- | --- |
| `offer` | [Offer](/business/nouns/offer) | Yes | The Offer to publish. |

## Outputs
| Output | Type | Required | Description |
| --- | --- | --- | --- |
| `offer` | [Offer](/business/nouns/offer) | Yes | The Offer, now open to accept. |

## Effects
- Emits [`Offer.published`](/business/events/Offer.published).
- Performed by the [Product Lead](/agents/product/product-lead).

## Refuses when
| Check | Error | Fix | Then call |
| --- | --- | --- | --- |
| The key is valid, but its scopes do not allow this operation. | [`forbidden`](/code/api/errors/forbidden) | Use a key whose scopes cover the operation, or ask an owner of the namespace to grant them. | [Offer.publish](/business/nouns/offer/publish) |
| The record is not in a state that allows this Verb, so the call is refused. | [`refused`](/code/api/errors/refused) | Read the record, run the Verb that moves it to an allowed state, then retry. | [Offer.publish](/business/nouns/offer/publish) |
| The median Customer’s Cost leaves less than the Startup’s target margin at this Price. | [`below-contribution-floor`](/code/api/errors/below-contribution-floor) | Raise the Price to the floor the error names, or grant fewer Entitlements. | [Offer.update](/business/nouns/offer/update) |

## When it waits
| Gate | Default |
| --- | --- |
| Decision class | Medium: two-way, visible |
| [Delay window](/systems/trust-and-governance/controls/one-way-windows) | 1 business hour, in which a watcher can pause, redirect or cancel it; then it runs. |
| Limit | The call [Limit](/business/nouns/limit) of the [Permission](/business/nouns/permission) it runs under. |
| Over the Limit | It waits `pending` for an [Approval](/business/nouns/approval) from the [Founder](/agents/founding/founder). Approved, it runs; refused, it ends `refused` with [`limit-exceeded`](/code/api/errors/limit-exceeded); unanswered by its deadline, it ends `canceled`. |
