Mercury API
REST API for Mercury business banking — programmatic access to accounts, transactions, wire/ACH transfers, and statements; ideal for startup treasury automation.
Viable option — review the tradeoffs
You need to automate treasury operations like fetching balances, transaction history, and initiating ACH/wire payments without manual banking logins.
Reliable for core reads/writes up to 100 free ACH/month; solid docs with code samples, but limited to existing recipients and no full Open Banking OAuth.
You want to build custom dashboards or sync financial data with internal tools for real-time visibility and automation.
Fast queries and easy accounting syncs; works great for startups but invoice API capped at 500/month on Plus plan ($29.90/mo).
Manual invoicing and payment tracking slows your billing cycle and reconciliation.
Streamlines small-scale billing excellently with auto-reconciliation; scales to thousands but hits plan limits on volume.
Payments to Existing Recipients Only
API initiates ACH/wires only to pre-saved recipients in your Mercury account—no dynamic recipient creation via API.
ACH Limits and Plan Tiers
100 free ACH payments/month standard; invoicing limited to 500 creations/month on Plus—exceed and upgrade or pay extra; monitor usage to avoid disruptions.
