- GET/whats-new$0.02Agent morning brief. One paid call returns the last 24 hours of AI pricing changes, new and removed models, service-status incidents, and top news headlines. The endpoint an agent calls on boot.
- GET/research
/citation-velocity$0.02Top 100 recent AI papers ranked by the share of their total citations earned in the most recent calendar year. Papers published in the last 2 years with 3+ citations. Surfaces papers that are still gaining traction now. OpenAlex CC0. - GET/ai-safety
/incidents /exposure$0.02AI safety incident exposure analytics. Per-developer and per-deployer incident counts with recency-weighted exposure_score (1.0 last 30d, 0.5 days 31-90, 0.25 older), risk_domain and SEP-view (Security/Ethics/Performance) distributions, top affected artifacts. Derived over the AVID (avidml/avid-db, MIT) snapshot refreshed daily. The "which AI vendors have the most recent reported safety incidents" call. - GET/research
/milestones$0.02Last 30 days of arXiv preprints flagged as milestone candidates by an offline Qwen 3.6 27B per-paper extraction pass. Each paper carries structured reasoning naming the benchmark + quantified delta, model release, or novel architecture justification. Conservative; false positives are worse than false negatives. - GET/funding
/exposure$0.1Derived structural metrics over the AI funding portfolio. Silicon-vendor concentration shares per investor, circular-loop classification (fully-circular / partial-loop / agnostic), co-investor pairs holding the same recipient, top recipients by inbound capital. The "who is funding whose silicon" call. - GET/inference-providers
/arbitrage$0.02Cross-provider arbitrage analytics for hosted inference. Per-model: cheapest_paid, most_expensive_paid, spread_usd, savings_pct, median_paid_blended, fastest_tps, cheapest_with_tps, free_tier_offers. Plus provider_rollup (cheapest_count, top_tps_count, value_score 0-100) and top_arbitrage models sorted by savings_pct desc. Pairs with the free /api/inference-providers matrix. The "where to migrate workloads" call. - GET/research
/emerging-keywords$0.02Top 50 multi-word keyphrases across recent arXiv AI abstracts ranked by recent-vs-baseline lift (last 30 days frequency over prior 90 days, smoothed). Each keyphrase carries 2-5 example arxiv_ids so an agent can drill into the underlying work. The trend-spotter feed for AI research vocabulary. - GET/policy
/timeline$0.02Forward and backward calendar over the AI policy registry. Each entry classified relative to now (past / active / upcoming), days-until-effective, with next-3-milestones for upcoming items. Filter by jurisdiction (EU, US, UK, etc) and time window. The "what AI rules are about to bite" feed. - GET/ai-cves
/ai-stack-cves$0.02AI-stack CVE intelligence. Filters fresh security disclosures to vendors and products in the AI inference, agent framework, training, vector DB, model gateway, and MCP tool layers. Each paper carries a tf_ai_category tag and a severity_rank, sorted with exploited-in-wild and critical-severity first. 99.8% of underlying data is from GitHub Security Advisories (CC BY 4.0).
