Authorizations

​
Authorization
string
header
required

API key from Settings > Developer > REST API

Headers

​
Moda-Version
enum<string>
default:2026-05-01

Calendar-dated API version pin. New integrations should pin 2026-05-01 to opt into the newest response shapes. For back-compat the server also accepts requests with no header and resolves them to the current default (today: 2026-04-12); that default advances on each sunset date. Any unsupported value returns 400 unsupported_version.

Available options:
2026-04-12,
2026-05-01
Example:

"2026-05-01"

Path Parameters

​
task_id
string
required

Prefixed task_ wire ID (Crockford base32 body). Path parameters additionally accept a bare UUID string for back-compat; JSON body fields require the prefixed form.

Pattern: ^task_[0-9A-HJKMNP-TV-Za-hjkmnp-tv-z]{26}$
Example:

"task_01HT9WK8N3M2J4A5Z6P7Q8R9TV"

Response

Successful Response

Canonical wire-format for every async design operation.

All consumers -- REST, webhooks, SSE, MCP -- serialize through Task.from_db() so the shape is always consistent.
