Changes
Added
auto_validate returns tweetAccounts (API 2.12.0): the X account behind each tweet condition and how it is billed. included accounts cost nothing extra; per_post accounts cost creditsPerPost for every post from the account (not replies or reposts), matched or not, while the query runs, on top of estimatedCredits. The auto_validate and auto_query_write descriptions tell agents to state that cost before activating.
Changed
- API v3 is free until 31 October 2026 on Pay-as-you-go and Grow (API 2.11.2). The v3 tool descriptions, server instructions and the bundle's tool list say so.
auto_query: method=get mentions the failure a query carries when it failed with a recorded reason (API 2.12.0).
auto_build says Builder Chat drafts tweet conditions only for accounts in Elfa's real-time set; for any other X account, write the condition yourself.
- Links point at the current docs.elfa.ai pages (
/tools/mcp, /tools/sdks, /api/v3/overview) instead of their redirects.
swagger.json is the published 3.0.0 spec.
Removed
auto_validate no longer returns estimatedCost. The API returns it only on x402, never to an API key, so it was always null here; estimatedCredits is the estimate.
