Short answer: Nevermined is payments infrastructure for AI agents rather than a consumer wallet. A person approves one capped, time-boxed spend mandate, and the agent pays for services by card or in stablecoins over x402 or MPP, while merchants use the same platform to sell to agents. Coinstancy Agentic Bank connects your AI to your own finances through a personal MCP, gives each agent a separate USDC wallet on Base with daily and monthly budgets and approval thresholds, and keeps workflows running with Cloud Run after the AI disconnects.
Key takeaways
- Nevermined serves both sides of agent payments: spend mandates and a Catalog MCP for buyers, and per-call, credit or subscription plans for merchants and API providers.
- Nevermined pays by card (Visa Agentic Tokens, Stripe, Braintree) or in stablecoins on Base and Tempo; Coinstancy Agentic Bank uses USDC on Base.
- A Nevermined mandate caps the total amount, the expiry and optionally the number of purchases; Coinstancy adds transaction, daily and monthly budgets, service allowlists, approval thresholds, simulation by default and receipts.
- Only Coinstancy links the agent to your portfolio, transactions, rates and investments, and runs scheduled or event-triggered workflows after your AI disconnects.
Nevermined vs Coinstancy at a Glance
Both products let an AI agent spend money on its own within limits a person sets, and both support x402, the open protocol that lets an agent pay for an API call in stablecoins over HTTP. They are built around different things: Nevermined around a payment mandate that works across cards and stablecoins, Coinstancy around a separate agent wallet tied to your own account. The table compares what each provider publishes, as read on November 11, 2026.
| Recurso | Nevermined | Coinstancy Agentic Bank |
|---|---|---|
| Built for | Teams, platforms, banks and payment providers letting agents spend under a mandate, and merchants or API providers selling to agents | People who want their AI to read their finances and spend within their rules |
| How the AI connects | Hosted Catalog MCP (API key or OAuth), plus the payments-py and @nevermined-io/payments SDKs and an API | Personal MCP for a compatible AI client, plus Cloud Run for workflows |
| Custódia | Cards held by the VGS card vault, never seen by Nevermined or the agent; organization USDC and EURC wallets are custodial, with Nevermined managing the signing key; custody of the personal wallet not documented | Custodial platform: the agent wallet sits in your Coinstancy account, separate from your main balance; no seed phrase to manage |
| Networks | Card rails (Visa Agentic Tokens, Stripe, Braintree); stablecoins on Base through x402 and on Tempo through MPP | Base |
| Ativos | Fiat by card; USDC and EURC on Base, USDC.e on Tempo | USDC |
| What the agent can do | Pay Catalog services and merchant plans per call over x402 or MPP; for sellers, charge agents with credit, time-based or dynamic plans | Approved x402 services and transfers between authorized agent wallets and pools |
| Spending limits | Spend mandate (delegation): total amount, expiry and optional number of purchases; group budgets on Premium and Enterprise plans | Transaction, daily and monthly budgets, service allowlists, prices and approval thresholds per agent |
| Human approval | A person approves the mandate once (passkey for Visa); the agent cannot set or raise it; no per-payment approval | Explicit confirmation before money moves through the MCP; approvals above the threshold you set |
| Safety checks | Immediate revocation, a record of every purchase, ISO 27001, SOC 2 Type II and PCI SAQ-D | Simulation on by default, receipts for every action, paid calls can be paused immediately |
| Access to your finances | No: payment history, budget and wallet balance only | Yes: portfolio, transactions, rates and investments through the personal MCP |
| Automation after the AI disconnects | Pays while your agent runs; no hosted scheduler documented | Cloud Run: scheduled or event-triggered workflows after your AI disconnects |
| Taxas | Personal account free with 2,000 catalog credits; Catalog $20 a month; organizations $50 to $500 a month; 2% on external services; merchants pay 1% (stablecoins) or 2% (cards) | No Agentic Bank fee published on the product page |
| Sign-up | Nevermined account with an API key or OAuth; card entered once in a browser; identity checks not documented | Coinstancy account with identity verification (KYC by Sumsub) |
How we compared: both products are described on the same points using each provider's own documentation and product page (see Sources). Where a provider does not document a point, we say so instead of guessing. Coinstancy publishes this guide and runs one of the two products compared.
What is Nevermined?
Nevermined calls itself "Payments Infrastructure for AI Agents." Its documentation describes a policy and control layer for agent payments: a person approves a spend mandate once, then the agent buys paid APIs and AI services on its own, by card or crypto, and every purchase is attributed. It is not a wallet app for end users; it targets teams giving their own agents a mandate, platforms letting their users' agents spend, banks and payment providers running the layer on their own rails, and merchants who want agents to find and pay for their services.
On the buyer side, the AI Services Catalog listed 163 services paid per call on the day we read it, for search, scraping, enrichment, filings and data, billed on one bill. On the seller side, merchants and API providers can charge agents per call over x402 or MPP, or by card into their own Stripe account.
Spend Mandates
A mandate, called a delegation in the docs, pairs a payment method with an amount, an expiry and an optional number of purchases. Nevermined checks it on every purchase, and the agent cannot raise it. One action revokes it, with no grace period.
Catalog MCP and SDKs
A hosted MCP server lets an AI client discover, quote and pay for Catalog services. It works with Claude Code, Codex, Cursor, Claude Desktop and ChatGPT, among others, through an API key or OAuth. Developers can also use the payments-py and @nevermined-io/payments SDKs.
Selling to Agents
Merchants can publish payment plans that are credit-based, time-based or dynamic, priced in ERC-20 tokens such as USDC or by card through Stripe, Braintree or Visa. Fiat plans can also settle per request over x402 against a card mandate.
How Nevermined Works
The agents guide follows four steps on the buyer side. Live keys make real charges; a sandbox environment uses test money.
Connect the Agent
Install the Catalog MCP and get an API key, which a person creates in one click, or connect through OAuth in a supported AI client. Discovering services needs no key.
Enroll a Card or Fund a Wallet
A person enters a card once in a browser, where it is tokenized by the VGS vault. For crypto payments, the agent draws on a funded stablecoin wallet instead.
Approve a Spend Mandate
The person sets the mandate's total amount, expiry and optional number of purchases. Visa mandates also need a passkey approval in the browser. To change a limit, you revoke the mandate and create a new one.
The Agent Pays Per Call
The agent quotes a service without being charged, then pays over x402 or MPP. Nevermined's routing fee comes out of the same cap, and a single call can be capped with a maximum total.
What is Coinstancy Agentic Bank?
Coinstancy Agentic Bank connects AI to financial action in three layers. Instead of a payment mandate on its own, it ties the agent to your Coinstancy account, with a policy you define and can see.
Personal MCP (Ask)
Connects your portfolio, transactions, rates and investments to a compatible AI client. The AI shows a quote or estimate, and you explicitly confirm each financial action before money moves.
Agent wallet (Authorise)
Each agent gets a separate USDC wallet on Base. You set its budget, allowed services, prices and approval thresholds. Autonomous spending stays within that wallet, never your main account.
Cloud Run (Automate)
Scheduled or event-triggered workflows keep running after your AI disconnects: trigger, check, act, trace. Simulate first, approve when required, inspect receipts and pause anytime. Wallet policy and cost limits still apply.
What can an agent pay for? Approved x402 services and transfers between authorized agent wallets and pools, within the service allowlists, spending limits and approval thresholds you define. Coinstancy is a custodial platform and requires identity verification when you open an account.
Principais Diferenças
The two products overlap on an agent paying for a service in USDC on Base through x402. Most differences come from who each one is designed for.
Payments Infrastructure vs Your Finances
Nevermined is a payment layer that businesses, platforms and banks build on, with a seller side for merchants. Coinstancy's personal MCP gives your AI client access to your portfolio, transactions, rates and investments, so it can answer questions about your money and prepare actions you confirm.
Cards and Two Chains vs USDC on Base
Nevermined pays by card or in stablecoins on Base and Tempo, over x402 or MPP. Coinstancy Agentic Bank uses USDC on Base and pays approved x402 services.
One Mandate vs a Wallet Policy
A Nevermined mandate caps a total, an expiry and a number of purchases, and organizations can add group budgets. Coinstancy sets transaction, daily and monthly budgets, allowed services, prices and approval thresholds for each agent wallet.
Automation
A Nevermined agent pays while it runs. Coinstancy Cloud Run keeps scheduled or event-triggered workflows going after your AI disconnects, under the same wallet policy and cost limits.
Spending Controls Compared
Giving an agent money is mostly a question of limits: how much it can spend, on what, and when a person must step in.
| Control | Nevermined | Coinstancy Agentic Bank |
|---|---|---|
| Por transação | Per-call maximum in the Catalog MCP; the mandate itself caps the total | Sim |
| Total cap with expiry | Sim | Not described |
| Number of purchases | Yes (optional) | Not described |
| Daily and monthly budgets | Group budgets per period on Premium and Enterprise; periods not documented | Sim |
| Service allowlist | Not documented | Sim |
| Approval above a threshold | Not documented (mandate approved once) | Sim |
| Simulation before acting | Not documented; a quote prices a call without charging | On by default |
| Receipts and pause | Record of every purchase; immediate revocation | Receipts for every action; paid calls can be paused immediately |
| Screening | Not documented | Not described on the product page |
"Not documented" means we did not find the control in the provider's public documentation on November 11, 2026; it does not prove the control is missing. Check each provider's current documentation before you rely on a control.
Which One Should You Choose?
Choose Nevermined If
You are building a product or a team setup where agents buy services by card or stablecoin under one mandate, you need Visa, Stripe or Braintree rails, or you want to sell your own API or agent to other agents per call.
Choose Coinstancy Agentic Bank If
You want your AI to work with your own finances, with daily and monthly budgets, service allowlists, approvals above a threshold, simulation and receipts, and workflows that keep running on schedule after the AI disconnects.
Using Both
Both pay x402 services in USDC on Base, so the protocol does not lock you in. Keep in mind that every extra payment method is another balance and another set of limits to watch.
