Verification: Checked on Oct 6, 2026 at 00:00 UTC without paying: the URL answered a valid x402 v2 challenge, on this host, that Burnbound can pay.

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

Get an agent key →

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

allowed hosts    websearch.use.x402atlas.com
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://websearch.use.x402atlas.com/search?chunks_per_source=2&query=latest+developments+in+AI+agents&search_depth=fast
