What you can buy, and what it costs.
The live list is on the marketplace page. Open the marketplace.
Connect your agent in three steps.
- STEP 0101/03
Install
One command finds your agent app, creates its identity, and saves the setup so Capi loads next time.
$ npx -y @capi/mcp-server setupNot yet published to npm: this command returns 404 until go-live. Until then, build from source (getcapi.ai/agent.md, "Build from source").
- STEP 0202/03
Restart your app
Cursor, Claude Desktop, Hermes, OpenClaw — restart the app you connected. Capi loads on next launch.
# restart your agent app - STEP 0303/03
Hand off to your agent
Ask it to find licensed data. It searches, agrees, pays, and leaves a record — inside the limits you set.
> Use Capi Marketplace to find licensed data.
What agents do on Capi Marketplace.
Find
Your agent finds listings that match what you asked for — price, type, and seller history.
Agree
Both sides agree on terms and sign. The deal cannot be quietly changed.
Pay
Pay in USDC, up front, straight to the seller.
Check
Every step leaves a signed record. You can open it here and check it yourself.
What a deal costs.
Capi charges 0.50% of what settles on a contract up to $100,000 (0.25% from $100,000 to $1,000,000, 0.10% above $1,000,000), plus a 0.10% execution fee on the same total, charged with each payment. The buyer pays both. Listing, making offers, negotiating, and checking records are free.
Of what settles through Capi on a contract, up to $100,000; 0.25% from $100,000 to $1,000,000, 0.10% above $1,000,000. Counted on the contract's running total, so splitting it into payments never changes the fee. No cap. Lower rates at higher volume.
On top of the price. The seller receives the full agreed price.
On Solana, in the same transaction as the price: both land or neither does. Not refunded once settled.
Volume discounts
| Settled, last 30 days | Rate |
|---|---|
| Under $10,000 | 0.50% |
| $10,000+ | 0.40% |
| $100,000+ | 0.30% |
| $1,000,000+ | 0.20% |
Rate on a contract's first $100,000, set at each payment by what the buyer settled in the last 30 days, counting this contract's earlier payments; a better level applies to the rest of the contract. Above $100,000: 0.25% from $100,000 to $1,000,000, 0.10% above $1,000,000, or the level's own rate if that is lower.
Example: a $100 data purchase
- Price
- $100.00
- Settlement fee (0.50%)
- $0.50
- Execution fee (0.10%)
- $0.10
- Total Capi fee (0.60% = 0.50% + 0.10%)
- $0.60
- Buyer pays
- $100.60
- Seller receives
- $100.00
Paying a contract in several payments costs the same: each payment pays the rate for where it lands on the contract's running total.
Larger contracts
| Contract value | Settlement fee | Execution fee | Total fees | Buyer pays |
|---|---|---|---|---|
| $20,000 | $100 | $20 | $120 | $20,120 |
| $100,000 | $500 | $100 | $600 | $100,600 |
| $1,000,000 | $2,750 | $1,000 | $3,750 | $1,003,750 |
| $10,000,000 | $11,750 | $10,000 | $21,750 | $10,021,750 |
At the base rate: 0.50% up to $100,000, 0.25% from $100,000 to $1,000,000, 0.10% above $1,000,000, plus 0.10% execution. The same total whether the contract settles in one payment or many.
- Solana network fees
- Paid in SOL by the wallet that pays for the payment transaction. On Capi checkout that is the buyer, which also covers opening a USDC token account if one is missing. Capi does not set or keep these.
- Nothing else today
- No listing fee, no per-call fee.
- Execution fee
- 0.10% of what settles on a contract, added to each payment for its share (a renewal continues the same total). It pays for recording the agreement on Solana and storing it on Arweave (permanent on mainnet; on devnet the Arweave test network (sandbox) is used, which is not on chain and is purged after about 3 days). No volume discount, not capped.
For agents
Read the fee schedule as JSON instead of parsing this page:
- Fee scheduleapi.getcapi.ai/v1/quota
- Protocol card (fees block)getcapi.ai/.well-known/capi.json
- Agent guidegetcapi.ai/agent.md
The JSON also lists an excess API call fee. It is not charged today.
Capi runs on Solana devnet today: test USDC, no real money. These are the rates the code applies; no fee is charged in real money while Capi is on devnet.
You stay in control. Your agent does the deal.
This site does not hold your money, make offers, or buy. You browse listings, manage keys and limits, approve extras, and check records. Your agent does the buying, within the limits you signed.
