API reference
Browser Agent API
Start an asynchronous browser agent: a hosted browser opens the page and the platform's model chooses navigate, click, type or done for up to eight steps. Returns a job; poll /v1/web/jobs/{job_id} for the final page, the extracted answer and every step taken.

Response fields and example
This example is illustrative, not a captured live response. Variable-cost operations may settle a charge different from the list price below. A successful response puts the platform payload in data and reports the exact credits used, remaining balance, request id and cache status beside it.
{
"success": true,
"platform": "web",
"endpoint": "/v1/web/agent",
"data": {
"id": "job_example",
"status": "queued"
},
"credits_used": 10,
"credits_remaining": 99,
"request_id": "req_…",
"cached": false
}The example is illustrative and shows a documented subset of data. The fields below are optional across supported sources; nullable fields can also be absent. Preserve unknown values and accept additional fields.
Schema basis: reviewed response shaper. See schema coverage and validation limits.
Download the data JSON Schema. Validate response.data, not the whole envelope. A valid shape does not establish that every field or source record was returned.
| Field inside data | Type | Meaning |
|---|---|---|
id | string | null | Exact source identifier; preserve it as a string. |
kind | string | null | kind |
status | string | null | status |
created_at | string | null | created at |
started_at | string | null | started at |
completed_at | string | null | completed at |
poll | string | null | poll |
refund_status | string | null | refund status |
credits_charged | number | null | credits charged; null is unknown. |
credits_refunded | number | null | credits refunded; null is unknown. |
attempts | number | null | attempts; null is unknown. |
progress | object | null | Nested response fields; optional unless explicitly documented. |
result | object | null | Nested response fields; optional unless explicitly documented. |
error | string | null | Failure details if present. |
This response accepts asynchronous work. Poll web/jobs/get for the result and per-page failures.
Failures use the typed error envelope. A confirmed uncharged or refunded failure reports zero; a pending reconciliation can report an unknown charge. Read credits_used and error.details.billing_status, and keep request_id for recovery. Response contract · Error reference
