# Create one entity text row

POST https://api.aventure.vc/v1/entities/{entityId}/texts
Content-Type: application/json

Create one text row owned by an entity. The selected text type is validated at write time; validation errors return field-level ProblemDetail details.

Reference: https://docs.aventure.vc/api-reference/a-venture-api/texts/create-entity-text

## Authentication

- `Authorization` header (bearer token, required) — User bearer token: Supabase or Clerk session JWT, Clerk OAuth access token, or Clerk personal API key
- `X-API-Key` header (required) — Admin API key for system-to-system write operations

## Request

### Path parameters

- `entityId` (string, required) — Entity UUID owning the text row

### Query parameters

- `sourceType` (enum, required) — Write provenance source type.
  - Allowed values: `requestChangeForm`, `newsArticle`, `blogArticle`, `firstPartyWebsite`, `relatedPartyWebsite`, `thirdPartyWebsite`, `llm`, `aventureStaff`
- `sourceDetail` (string, required) — Source detail or reviewer reference for the write.
- `sourceProvider` (string, optional) — Provider name for provider-native IDs or slugs.
- `sourceProviderId` (string, optional) — Provider-native source ID.
- `sourceProviderSlug` (string, optional) — Provider-native source slug.
- `actorType` (enum, optional) — Actor type; inferred as agent when agentChassis and agentModel are supplied, or as employee from an authenticated user JWT session.
  - Allowed values: `agent`, `employee`
- `agentChassis` (string, optional) — Agent chassis token for agent-authored writes.
- `agentModel` (string, optional) — Agent model id for agent-authored writes.

### Body (application/json)

- `allowPublicEntityTextWordLimitOverride` (boolean, optional, nullable) — Admin override for public entity text word limits; use only with explicit approval.
- `allowSuspectedShellStrip` (boolean, optional, nullable) — Allow intentional magnitude phrases without a currency marker ('100K customers') or intentional escape sequences before '$'; never use this to persist corrupted currency text — write '$' literally instead.
- `isCurrent` (boolean, optional, nullable) — Current row. Create defaults to true; inactive rows are hidden from default lists.
- `isPrimary` (boolean, optional, nullable) — Primary row. Create defaults to true; inactive rows are not primary.
- `source` (string, optional, nullable) — Source note for the text row.
- `text` (string, optional, nullable) — Text body for the selected text type. Entity create requires both a summary row and an expanded row. Shape: summary is a single short sentence; expanded is split into paragraphs by one blank line ("\n\n" in JSON). Run GET /v1/entities/texts/types (CLI: entities texts types list --data) before writing to inspect each textType's minWords, maxWords, rewriteHint, and paragraphShape contract. Write '$' literally in currency amounts; escaped forms like '\$50M' are rejected as shell artifacts.
- `textName` (string, optional, nullable) — Optional name for this text row.
- `textType` (string, optional, nullable) — Canonical text slot to write, such as summary or expanded

## Response

### 201

Created

- `id` (integer, required) — Type-safe identifier for text records
- `owner` (object, required) — Owning record, nested ids only: owner.entityId or owner.personId — exactly one is set, and no name fields. Writes are scoped by the owning entity/person route; owner is never a write field.
  - `entityId` (string, optional, nullable) — Canonical entity UUID
  - `personId` (string, optional, nullable) — Canonical person UUID
- `text` (string, required)
- `textType` (string, required) — Value object for text type classification
- `compliance` (object, optional, nullable) — Derived character/word counts and governed-contract compliance for this text row; null when not evaluated.
  - `characterCount` (integer, required) — Character count of the row text (UTF-16 units).
  - `meetsRequirements` (boolean, required) — Whether the text satisfies every governed contract rule.
  - `violation` (list of string, required) — One human-readable reason per unmet rule; empty when compliant.
  - `wordCount` (integer, required) — Word count of the row text (whitespace-separated tokens).
- `createdAt` (datetime, optional, nullable)
- `isCurrent` (boolean, optional, nullable)
- `isPrimary` (boolean, optional, nullable)
- `language` (string, optional, nullable)
- `source` (string, optional, nullable)
- `textName` (string, optional, nullable)
- `updatedAt` (datetime, optional, nullable)
