What else is out there, and when you should buy it instead
We are not the only tool for watching what your agents pay. Here is the honest map of the category, and where each type of tool — including ours — actually fits.
One question decides this
Forget feature grids. Answer one thing: do you need the payment blocked, or do you need to know it happened?
If the answer is blocked — a compromised agent, a customer-funds scenario, a hard compliance ceiling — buy an enforcement layer and stop reading comparisons. Nothing observational closes that gap, including us. We watch settled chain data; by the time we see a transfer, the money is already gone.
If the answer is know — magnitude, drift, which agent went over — then enforcement is a large integration bill for a problem you do not have. What you have is an attribution problem, and that is what we built.
The category, by type
| Category | Answers | Integration | Scope |
|---|---|---|---|
| Explorers | What is happening on a protocol, across every wallet | None — browse a public index | Protocol-wide, not fleet-specific |
| Policy engines / enforcement layers | Can this payment be blocked before it happens | Sits in the agent's request path | Per-transaction rules, allowlists, kill switches |
| Cross-rail cost trackers | Total agent cost across model spend and payment rails combined | Multiple connectors to configure | Broader than payments alone |
| Read-only ledgers (this is us) | What did my fleet spend, per agent, against a ceiling I set | A public wallet address, nothing else | Base and Solana, per-agent attribution |
Why teams pick AgentCap
- Zero integration — a public wallet address is the whole setup, nothing to wire in.
- Nothing to drain — we never hold a key or ask for wallet approval, so there is nothing an integration mistake could lose.
- Per-agent attribution across both Base and Solana in one ledger, not one tool per chain.
When to reach for something else instead
AgentCap covers the attribution problem well. A few adjacent needs are out of scope by design, and worth knowing about:
- Need the payment blocked, not just visible? Pair us with an enforcement layer that sits in the agent's request path.
- Need protocol-wide visibility beyond your own fleet? An explorer covers that broader surface.
- Need total cost including model inference, not just payment-rail spend? A cross-rail tracker adds that on top.
If a read-only ledger is what you need
Paste a public address and see every USDC payment on Base and Solana, attributed per agent, against a ceiling you set.
