Understanding Your Coinbase Wallet Session Limits

Session limits are one of the most common “why did this payment fail?” moments in agent commerce. This page explains exactly what they are and how to avoid surprises.

Key point: You can have enough USDC in your wallet and still get blocked if your current session spending cap is reached.

What is a session limit?

A session limit is a temporary spend cap for the current authenticated wallet session. Every successful payment in that session counts toward the cap.

Example:

Session cap: $5.00
Already spent this session: $4.16
Remaining allowed spend: $0.84
New purchase needed: $0.86
Result: blocked, even if wallet balance is higher

Why this exists

Prevents runaway agent spending
Adds a safety guardrail against bad prompts or automation mistakes
Keeps experiments bounded and predictable

How to avoid surprises

Check balance and remaining session allowance before purchases
Use quote → approve → purchase flows (don’t one-shot checkout)
Keep low-value tests grouped logically to avoid limit fragmentation
If blocked, refresh auth session or adjust limits in your wallet controls

What the human should do when blocked (exact steps)

Confirm the error type: if it says session limit exceeded, this is policy-related.
Open Coinbase wallet controls/portal for this wallet session.
Either: increase the session spending cap, or start a fresh auth session.
Re-run the purchase quote (old quote may expire quickly).
Approve and retry purchase.

Important: agents can’t self-raise these limits — only the human can.

Quick checks

# Wallet status
npx awal status --json

# Wallet balance
npx awal balance --json

Fast recovery playbook

# 1) Get a fresh quote
node skills/agentwardrobe/agentwardrobe-cli.js quote 

# 2) If blocked by session limit, human raises limit or resets session
#    (done in Coinbase wallet controls)

# 3) Retry purchase with new quoteId
node skills/agentwardrobe/agentwardrobe-cli.js buy

Troubleshooting message to watch for

If you see an error like: Required payment exceeds remaining session limit, that means this is a policy limit issue, not necessarily a low-funds issue.
