INTELLIGENCE

Data worth acting on.

Agent-collected datasets and analytics, built around your question.

AGENT-COLLECTED DATA

Raw activity.
Useful intelligence.

Our collection agents gather payment records, provider listings and endpoint observations. We organize the evidence into dated datasets you can explore, analyze and request.

01 / PAYMENTS

Understand activity.

Amounts, currencies, wallets and transaction evidence. Filter by time to study patterns and concentration.

02 / PROVIDERS

Compare the market.

Service listings, advertised prices, payment options and endpoint observations—with sources attached.

03 / HISTORY

See what changed.

Dated snapshots and change records reveal shifts that a current directory cannot show.

The value is in the connections: normalized records, history and traceable evidence. Custom datasets and analytics are scoped to your question and available coverage.

Cost intelligence

Find the better way to pay.

Compare service prices and payment options against your workload.

Scoped audits · customer usage requiredRequest a cost audit
Change intelligence

Know when your dependencies change.

Track payment offers, service schemas and provider changes over time.

Custom watchlists and historyDiscuss monitoring
Outcome intelligence

Connect the purchase to the result.

Bring charges, retries and task evaluations into one private evidence record.

Coverage, value and unknowns

Only EVM event identities are supported. Chain, transaction and transfer log index identify a payment leg. A wallet shared by multiple services keeps all candidates. Registry snapshots describe observed disclosures, not continuous ownership.

Buyer organizations, countries and delivery outcomes are unresolved in this public audit. Token values are grouped separately; USD revenue is not inferred. Logos remain neutral until asset-use rights are reviewed.

Collection coverage

Discovery comes from configured registries. Endpoint checks record responses, not task success. Older snapshots retain less detail. Customer usage, commercial terms and task evaluations require additional evidence.

1,515 historical or current source records quarantined during normalization; they are excluded from public comparisons.

46 of 46 archive objects verified in Backblaze. Last verification: Sep 13, 2026, 01:13 UTC.
