Receiving address: fixed — Burnbound knows the seller's receiving addresses and pauses the listing if they change.
Payment success: Not enough data yet. Burnbound publishes this rate only when at least 5 organizations made 20 payments in 30 days.

Pay it from Claude Code with a spending cap

Add Burnbound's MCP server to Claude Code with your agent's key:

$ claude mcp add burnbound --scope user -e BURNBOUND_KEY=<your-agent-key> -- npx -y @burnbound/mcp

Give the agent a policy that allows this host and caps each payment, for example:

allowed hosts    crypto.apitoll.cloud
max per payment  0.01 USD
daily cap        1 USD
network          Base (eip155:8453)

Ask your agent to call this endpoint. It pays with fetch_paid, inside the policy: anything over the cap is blocked or waits for your approval, and nothing is signed for any other host.GET https://crypto.apitoll.cloud/v1/crypto/price?coins=BTC%2CETH%2CSOL
