### Tool changes

- 2026-10-20 `get_sentiment` added
  - Paid endpoint ($0.002): crypto news sentiment for one asset: -1..1 score, bearish/neutral/bullish label, pos/neg/neu headline counts and up to 5 top headlines with links. Headlines labeled by a local LLM, score is plain math, refreshed about every 15 min. Symbols not in the current snapshot or stale data return an error and no charge (free list: GET /sentiment). Returns the x402 payment requirements and URL.
- 2026-10-20 `request_report_schedule` added
  - Free: tell cryptofeed402 how often you want briefs/reports and the best UTC hours to have a fresh one ready, so we can schedule to match. Logged as aggregate demand (GET /feedback/schedule shows counts only; notes and agent names are never published; no IPs stored). Limit 10/hour/IP.
- 2026-10-19 `audit_agent_ready` added
  - Paid endpoint ($0.05): audits a public website or x402 API for AI-agent readiness (llms.txt, robots.txt AI rules, sitemap, OpenAPI, /.well-known/x402, agent card, MCP initialize, a live unpaid 402 challenge, Bazaar metadata, Roundhouse / 402 Index / x402 Doctor listings). Deterministic, no LLM. Returns the x402 payment requirements and URL; see get_audit_sample for the output format.
- 2026-10-19 `get_perps` added
  - Paid endpoint ($0.002): one Hyperliquid perp's funding (hourly, 8h, annualized), open interest in USD, 24h volume, mark/oracle price, premium and whether it is in the top-10 funding extremes. Any listed Hyperliquid perp; unknown symbols return an error and no charge. Returns the x402 payment requirements and URL.
- 2026-10-19 `get_audit_sample` added
  - Free: a cached example agent-readiness audit of cryptofeed402.site (score 0-100, pass/warn/fail per check with evidence and fixes) so you can see the output of audit_agent_ready before paying.
- 2026-10-19 `get_top_requested_assets` added
  - Free: top 20 coins other agents have asked cryptofeed402 to monitor in the last 30 days (aggregate counts only).
- 2026-10-19 `request_asset` added
  - Free: ask cryptofeed402 to consider monitoring a coin it does not cover yet (covered: BTC, ETH, SOL, HYPE, NEAR, AAVE). Logged for human review; high-demand assets may be added to the brief and paid endpoints later. Not a guarantee. Limit 10/hour/IP; repeat asks for the same symbol within 24h count once.
