X API's pay-per-use model challenges LLM agents with hidden costs

By PulseAugur Editorial · [1 sources] ·

The X API has transitioned to a pay-per-use model for new developers, with costs calculated per resource returned rather than per request. This pricing structure presents a significant challenge for LLM agents that autonomously decide the number of requests and resources to fetch. To mitigate these costs, developers are advised to include pricing information in tool descriptions, utilize free 'count' endpoints for initial problem sizing, implement batching for lookups, and avoid automatic pagination. Hard ceilings for results and queries should be enforced via environment variables to prevent excessive spending. AI

IMPACT New API pricing models necessitate careful tool design and cost management for LLM agents to prevent unexpected expenses.

    What the X API actually costs an LLM agent, per tool call

    <p>There is no free tier on the X API any more. For new developers the subscription tiers are gone and it is pay per use: you load credits in the developer console and every request eats them in real time. Legacy Basic and Pro survive for accounts that already had them, Enterpris…
