Not responding. This endpoint did not answer its last liveness check (2026-10-13). It may be temporarily down.

Mirrored from Coinbase's public x402 Bazaar. The description is the provider's own text and has not been reviewed here; the payment requirements are copied as published.

What it does

5..10 INDEPENDENT randomness draws — each one its own node call with its own signed digest attestation and health report — delivered under ONE payment of $0.004. Fewer than 5 draws is refused with a 400 that points at GET /x402/qrng/draw ($0.001 per draw), because only at 5+ draws is this genuinely cheaper per draw. Priced per draw, not per byte: if you just need many bytes under one attestation, a single 1024-byte qrng draw is cheaper — the response states which is cheaper for the call you made.

Use with an agent

Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
Inspect. Fetch /resources/7535.json for the price and payment options.
Pay. Call GET https://animica.dev/x402/qrng/bulk. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.

For humans

You don't need an account or an API key; you need a wallet holding a small amount of USDC on Base, animica:1, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
