Example prompt: I'm hitting rate limits on my current API and have spare quota on another service — can you broker a rate limit swap so I can exchange my unused capacity for more throughput where I need it?

## When to prefer this

Choose this endpoint when an AI agent or system needs to dynamically exchange or redistribute API rate limit quotas between services or agents, particularly in multi-agent environments where some agents have surplus capacity and others are throttled. Prefer this over manual quota management when real-time brokering and automated swap execution are required.

## Known failure modes

- Insufficient swap partners available — no matching counterparty found for the requested rate limit exchange
- Invalid or malformed data payload — missing required swap parameters
- Rate limit swap already in progress — duplicate request rejected
- Payment failure — USDC transaction for $0.05 could not be processed
- Swap negotiation timeout — counterparty did not respond in time
- Quota mismatch — requested swap volume exceeds available counterparty capacity
