No worker heartbeats received yet.
The indexer fleet (webhook ingest, backfill, scoring, reconciler) will start reporting here once it ships.

Active prober · mystery shopper

SPX402 buys from x402 services to measure what passive indexing cannot see: whether a challenge is well-formed, whether payment actually settles, and whether anything is delivered. Every probe announces itself as SPX402-Probe/1.0. Probe results are not scored.

No probes recorded yet. The lane is scheduled and visible; it stays at zero until the prober is enabled and funded — see Active verification.

Probe log · most recent
No probe has ever been recorded. Nothing has been bought, so nothing is claimed.
Decoder coveragelast 7 daysEvery event type SPX402 decoded in the last week, grouped by agent category. An empty row means a dark category — the chain produced events we did not yet recognize.
No events decoded in the last 7 days.
Facilitator registryv0.3.0Tier A x402 detection recognises a settlement when the transaction fee-payer is a known facilitator. An address is only activated once the operator publishes it and a captured fixture proves detection. Addresses are never inferred from chain traffic.
0active · 0 tracked
No facilitator addresses registered. Tier A detection is inactive; x402 settlements are detected via Tier B (memo / protocol markers) only, at medium confidence.
Known parser limitations
  • • Custom buyback routes outside published Pump/PumpSwap IDLs surface as low-confidence events.
  • • Multi-step burn sequences across multiple slots may be reconciled with up to 90 seconds of delay.
  • • Off-chain operator activity is, by definition, invisible to SPX402.
