Animica Chain Anomaly Detector
x402
Animica Chain Anomaly Detector is a paid API for AI agents from animica.dev, paid per call via x402, $0.002511/call, status unknown (last checked 2026-09-15).
Analyses recent blockchain blocks to detect anomalies in block intervals, empty-block runs, difficulty jumps, mempool state, and block-producer concentration shifts.

How this service works
Animica Python Cloud: deploy a Python function to animica.dev, get a public endpoint, and earn ANM every time someone runs it. Free AI (OpenAI-compatible, no key), free scheduled Workers, and an 80/20 developer split.
Output
A JSON object containing flagged anomalies across the requested window: interval outliers (blocks far above the median), runs of consecutive empty blocks, difficulty (thetaMicro) jumps between consecutive blocks, block-producer concentration statistics including HHI values and mover addresses, and node read latency in milliseconds. If attestation was requested, an ML-DSA-65 signature binding the report to the chain height is also returned.
Example use cases
Centralisation alert for staking monitor
“Analyse the last 240 Animica blocks and flag if any single payout address produced more than 40% of blocks in the recent half, and tell me if the HHI shifted by more than 0.2 between the two halves.”
Quick interval anomaly check
“Scan the last 60 Animica blocks just for interval outliers and empty-block runs — I don't need producer analysis, I just want to know if there are any weird gaps or consecutive empty blocks, with a threshold of 10 empty blocks in a row.”
Auditable anomaly report with attestation
“Give me a full anomaly report on the last 180 Animica blocks including producer concentration analysis, and attach an ML-DSA-65 attestation so I can verify this report was pinned to the actual chain height.”
Technical details
Endpoint
POSThttps://animica.dev/x402/chain/anomaliesWhen to prefer
Choose this endpoint when you need on-chain anomaly detection specifically on the Animica blockchain — particularly for producer concentration shifts, difficulty spikes, or sustained empty-block runs. It is the right choice when you want a single structured report covering multiple anomaly dimensions in one call, especially when cryptographic attestation of the result is required. Prefer it over general block explorers when you need programmatic, threshold-driven flagging rather than manual inspection.
Side effects
- Block count out of range (must be 12–240) returns a validation error
- Head margin exceeding available chain depth may cause a node read failure
- Long windows (240 blocks with producer analysis) can time out if node load is high
- Invalid threshold values (e.g. hhi_shift > 1 or theta_jump_ratio <= 1) return parameter errors
- Payment failure or insufficient USDC balance returns a 402 response before any analysis
