Charles Schwab Rate Limits

Schwab rate limits are enforced per OAuth 2.0 application / user token across the Trader and Market Data APIs. Numeric per-second/per-minute limits are gated behind the Schwab Developer Portal login and not publicly published; consumers should expect 429 responses and use exponential backoff.

Charles Schwab Rate Limits is the machine-readable rate-limit profile for Charles Schwab on the APIs.io network, in the API Commons Rate Limits shape.

It captures 3 rate-limit definitions, measuring requests_per_minute and concurrent_connections.

An exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes 4 backoff/retry policies defined and response codes documented for throttled, unauthorized, and serviceUnavailable.

Tagged areas include Rate Limiting, Brokerage, Trading, and Market Data.

Policies

OAuth 2.0
All endpoints require OAuth 2.0 access tokens. Refresh tokens have documented lifetimes requiring periodic re-auth.
Backoff Strategy
Use exponential backoff on 429/503 and honor Retry-After when present.
Order throttling
Order placement endpoints have lower limits than read-only balance/position queries to protect brokerage infrastructure.
Streaming entitlements
Streaming and real-time market data are subject to exchange entitlement rules; NBBO vs Level 1/2 access depends on user agreements.
