Usage

What every agent seat includes

Each activated AI agent enrolled in Mercury counts as one seat. Every seat comes with included interaction, storage, and policy evaluation pools.

Interactions 100 300 1,000+
Encrypted storage 1 GB 2 GB 10 GB
Policy evaluation credits 50,000 100,000 500,000+

Pools scale linearly. 50 Guardian seats = 15,000 interactions + 100 GB storage + 5M policy credits per month.

Overage

Predictable overage rates

When agents exceed included pools, overage is billed at flat unit rates. Same rates across all tiers.

Meter Rate
Interactions $0.15 per interaction

Regulatory coverage

One engine, configurable by industry

Healthcare (HIPAA) scanning is included in all tiers. Every tier provides ingestion, encrypted retention, and audit logging for both regulated and non-regulated agents. Add rule packs as your agents expand into new verticals.

Rule Pack Annual Org-Wide (default) Per Seat (exception)
Healthcare (HIPAA) Included Included
Debt Collection (FDCPA, Reg F, TCPA) $7,500/yr ($625/mo) $10/seat/mo
Insurance (GLBA, state regulations) $7,500/yr ($625/mo) $10/seat/mo
Financial Services (GLBA, Safeguards, AML/KYC) $15,000/yr ($1,250/mo) $10/seat/mo
PCI DSS (payment flows) $5,000/yr (~$417/mo) $10/seat/mo
Telemarketing (TCPA, FCC, DNC) $5,000/yr (~$417/mo) $10/seat/mo

Annual org-wide is the default. A rule pack is what lets your company operate AI agents inside a regulated framework (HIPAA, FDCPA, GLBA, PCI DSS, TCPA), so we price it per company per year. Same way Vanta and Drata sell their framework add-ons.

Per-seat is available on request for agencies whose clients span more than one regulatory vertical, for teams piloting a rule pack on a few agents before rolling it out company-wide, and for platforms whose tenants don't all need the same coverage. Flat $10 per seat per month across every rule pack.

Bundle discounts on annual org-wide pricing: 2 packs 15% off · 3 packs 25% off · 4+ packs 35% off (or upgrade to Citadel where all packs are included).

Guardian includes 1 additional rule pack. Citadel includes all rule packs.

FAQ

Mercury pricing. Common questions about Mercury pricing, billing, and plans for AI agents

No. Mercury serves both regulated and non-regulated deployments. Every tier provides encrypted data ingestion, immutable audit logging, and retention for any AI agent interaction. Sentinel is designed for non-regulated or lightly-regulated agents that benefit from centralized logging, interaction storage, and operational governance without a regulatory mandate. Guardian and Citadel add active compliance scanning, policy enforcement, and evidence packaging for agents operating under HIPAA, FDCPA, GLBA, PCI DSS, TCPA, or other regulatory frameworks.
If your agents handle regulated data (PHI, PII, financial records), start at Guardian. Guardian provides 6-year HIPAA-compliant retention, active compliance scanning, policy enforcement, and 37 EHR/PMS connectors and 200 integrations. If your agents are non-regulated (internal automation agents, lightly-regulated workflows), Sentinel provides compliant storage and audit trails at $30/seat.
Each activated AI agent enrolled in Mercury counts as one seat. Seats are billed monthly at a fixed rate based on your tier: $30/seat on Sentinel or $25/seat on Guardian. Each seat includes interaction, storage, and policy evaluation pools that scale linearly with seat count. Overage applies when agents exceed included pools.
All tiers include a 7-day free trial. Billing begins after the trial ends, regardless of individual seat activation timing. Annual pre-pay discounts are available: Sentinel at $25/seat and Guardian at $21/seat.
Overage is billed at predictable unit rates: $0.15 per interaction, $0.22 per GB-month of storage, and $0.35 per 10,000 policy evaluation credits. These rates are the same across all tiers. Pools scale linearly with seats, so adding seats increases your included allocation.
Yes. Upgrade at any time. Data and configuration migrate seamlessly. Many teams start with Sentinel and upgrade to Guardian when they enter regulated markets or need active compliance scanning and enforcement.
Healthcare (HIPAA) scanning is included in all tiers. Additional rule packs (FDCPA, Insurance, GLBA, PCI DSS, TCPA) can be added per seat or org-wide. Guardian includes one additional rule pack. Citadel includes all rule packs. Organizations running 3+ packs receive 20-25% bundled pricing.
Building internally requires 6-12 months of engineering, ongoing regulatory maintenance across multiple frameworks, and multi-vertical expertise. Mercury provides production-ready compliance infrastructure from day one. One integration covers every regulated vertical. Teams typically see ROI within the first customer deployment.
Hello is Hello Voice plus Hello Mercury for practices: included Mercury has no separate fee. Hello Voice Pay as you go includes Guardian seats scaled to call volume; Hello Enterprise includes Guardian or Citadel allocation sized to scope, with included interaction, storage, and policy evaluation pools on Hello pricing. Each additional Mercury seat is $25/month (Guardian list parity). Mercury is also available standalone for any AI agent platform via webhooks.
