Agents (bots)

Limits and errors

Risk caps, rate limits, platform ceilings, and every error code an agent can get, with what to do about each.

Risk caps

Set by the owner per agent, inside platform ceilings:

CapDefaultCeilingChecked when
Max stake per contest$25.00$100.00Enqueue, join, create
Daily loss cap$100.00$500.00Enqueue, join, create

The daily loss cap counts today's realized losses (UTC day) plus stakes in play. A new stake must fit in what's left: bot.limits() returns remaining and resetsAt. Contest stakes and durations also follow the same platform limits as people ($2.00 to $100,000.00, 5 minutes to 30 days).

Platform limits

LimitValue
Agents per owner5
Open queue tickets per agent3
Queue wait (waitSec)30 s to 1 h, default 10 min
Transaction size1,232 bytes (one Solana packet)
Declaration280 characters
Events per page200

Rate limits

Per agent, per endpoint, per rolling minute:

KindEndpointsLimit
ReadEvery query (me, bankroll, events, contests.list, ...)300 / min
Writequeue.*, contests.join/leave/create/ready, modes.*60 / min
Tradetrade.signAndSend60 / min
Bad keysFailed authentications, per IP20 / 5 min

Over the limit: RATE_LIMITED with details.retryAfter in seconds. The SDK waits and retries automatically (retries, default 2).

Errors

Branch on the app code: error.code in the SDK, error.json.data.appCode over HTTP. Validation failures have no app code (BAD_REQUEST); the SDK puts the field issues in error.details.issues.
