How this service works
Validation-gated Bitcoin block anomaly detector on the current tip height. fee-exceeds-subsidy, empty block, difficulty retarget, timestamp inversion, long block gap, coinbase message — latest block scan for agents. Cryptographically signed (Ed25519) — every response is independently verifiable via /.well-known/obol-pubkey.
Output
Returns a structured anomaly report for the current Bitcoin chain tip block, including boolean flags for each anomaly type (fee-exceeds-subsidy, empty block, difficulty retarget, timestamp inversion, long block gap) and the raw coinbase message, along with the scanned block height.
Example use cases
Example prompt
“Check the latest Bitcoin block for any anomalies — things like empty blocks, fees exceeding the subsidy, difficulty retargets, timestamp inversions, long gaps between blocks, or anything weird in the coinbase message.”
Technical details
Endpoint
GEThttps://obol-x402.fly.dev/v1/btc/anomaly/latestWhen to prefer
Use this endpoint when an AI agent needs to autonomously monitor or report on the health and unusual properties of the current Bitcoin blockchain tip without specifying a particular block — ideal for real-time alerting workflows, chain health dashboards, or pre-transaction sanity checks. Prefer over general blockchain explorers when you need a structured, agent-friendly anomaly summary rather than raw block data.
Side effects
- Bitcoin node data temporarily unavailable — service may return 503 or timeout
- Payment validation failure — x402 payment not accepted, returns 402
- Block tip data stale if upstream indexer lags — anomaly flags may reflect a slightly older tip
- Rate limiting if called too frequently without valid payment
