Limits

Infragrid validates inputs before dispatch and bounds public outputs. Design integrations within these limits.

Requests and workflows

Field	Limit
Free-form task	20,000 characters
Metadata	16 KB serialized JSON object
Workflow	100 steps and 128 KB serialized JSON
Explicit wait	100–30,000 ms
Navigation URL	2,048 characters; absolute HTTP(S); no embedded credentials
Workflow/output name or keyboard key	100 characters
CSS selector	1,000 characters
Search query	2,000 characters
AI instruction or summary	4,000 characters
Select value	4,000 characters
Typed text	20,000 characters
`act` step	12 browser actions
Extraction schema	Object-shaped JSON Schema

Unknown fields and type coercion are rejected. Both SDK builders revalidate values after variable substitution.

Identifiers and pagination

Field	Limit
Run or resource ID accepted by SDK/MCP	200 characters
Standard list page	1–100 items
Browser-run offset	0–1,000,000
Blueprint-run cursor	512 characters
Idempotency key	1–255 printable ASCII characters without spaces
API key	`ig_live_` prefix, printable ASCII, at most 4,096 characters

Responses

SDK transports read at most 1 MiB per response. Oversized successful responses fail closed as APIConnectionError. Oversized error bodies are discarded before status classification. The MCP adapter returns at most 256 KB of JSON tool output and converts larger results into a bounded tool error.

Concurrency and quotas

Workspace concurrency and credit availability are enforced by the API and can change by plan. Treat 402, 409, and 429 as control-plane decisions, and follow Retry-After when the response provides it.

Do not derive platform limits from visible work-log rows. One browser action can produce multiple UI activity entries.
