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

Store a JSON document (object or string, up to 8 KB) on IPFS through a managed pinning service and return its content identifier (CID v1) plus an HTTP gateway URL. MUST be invoked when an agent needs durable, content-addressed storage for memory, decisions, artifacts or metadata that other agents can fetch by CID. Do NOT send raw binary, files over 8 KB, or an existing CID to re-pin. Settles $0.008 USDC via x402 on Base; failed or unavailable pins are never charged; receipts at /api/ledger.

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/6770.json for the price and payment options.
Pay. Call GET https://enclave402.com/api/storage/pin. 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, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
