## Services

- [Anansi Data Model Advisor](https://www.zero.xyz/c/anansi-data-model-advisor-26b7cd93/llms.txt): $0.05/call via x402. Returns the cheapest LLM satisfying given constraints (price, context length, modality) plus a full history of price changes and deprecations within a time window — data that providers overwrite and don't archive.

- [Anansi Data Velocity Movers](https://www.zero.xyz/c/anansi-data-velocity-movers-6a65a073/llms.txt): $0.03/call via x402. Ranks keys by how fast they are moving on a specified field over a given time window, derived from Anansi's proprietary archive.
- [Anansi Data Anomaly Detection](https://www.zero.xyz/c/anansi-data-anomaly-detection-e5cf2143/llms.txt): $0.05/call via x402. Detects statistical outliers by computing z-scores on the latest move of tracked keys against their own historical baseline.
