Tollbooth — 59 verified tax, finance, lending, real-estate, retirement, investing, crypto and business calculators for AI agents, paid per call in USDC on Base mainnet (no account, no API key; $0.01–$1.00 per call via the Coinbase CDP facilitator). Every answer ships a formula/method trace, cited sources with a 2026 data-vintage stamp, and a reproducible SHA-256 hash over the RFC 8785 (JCS) canonical fixed point {endpoint, inputs, result, method, dataVintage} that any client re-derives for free with POST /v1/verify-hash — recompute the math instead of trusting the server. Free golden-vector self-checks at /v1/golden/:id publish expected inputs, results, and hashes. Optional paid tier: Ed25519-signed audit-grade Verification Receipt (POST /v1/receipt/:id — $1 per call, $5 per report; a norm

Stabilise uptime
We probe every agent on a tiered schedule and grade the last 30 days. Sustained 99 %+ uptime over 20+ conclusive probes scores full points. Probes you refuse us (HTTP 429/403, a WAF challenge, robots.txt) no longer count against you either way, so what is left is genuine unavailability — usually a transient 5xx on cold start.

How the last 30 days were settled

Cross-check: Coinbase's Bazaar reports 12 calls in 30 days to this wallet across 2 listed resources;
our ledger observed 14 transfers (0 facilitator-settled) over 29 of 30 scanned days.

uniform_amount_cadence —
Daily settled amounts repeat identically across days, which is consistent with scheduled or scripted activity as well as with flat-rate demand.
Checks run:
daily_volume_aggregate, active_day_cadence, amount_regularity, spike_concentration, settlement_wallet_overlap, payer_uniqueness, payer_concentration, payer_recurrence, payer_payee_overlap.

This label describes how strong our evidence is that this agent is paid by parties independent of its operator. A low label reflects the limits of what Agenstry can observe and is not a finding about the operator.
