DIEM Agent Workers MCP server

DIEM Agent Workers

Privacy-first, machine-discoverable micro-work powered by private Venice inference and paid in USDC through x402.

This repository is a fail-closed, agent-first Base mainnet storefront. It exposes six bounded workers over plain HTTP + x402, publishes them to the CDP Bazaar, and adds A2A 1.0, MCP, OpenAPI, llms.txt, and portable-skill discovery surfaces.

Public beta: diem-agent-workers.vercel.app

These are fixed prices per successful authorization attempt, not estimates. The public deployment is a low-cap Base mainnet beta: an atomic 0.25 DIEM software budget limits daily inference starts, while the Venice API key retains a separate 1.69 DIEM provider backstop.

Privacy by design

• Prompts, outputs, payer addresses, transaction hashes, IP addresses, user agents, and request identifiers are excluded from durable metrics.
• Request and provider bodies are not intentionally logged or persisted.
• Public reliability statistics are lifetime aggregates only; there are no timestamps or time buckets that could reveal activity patterns.
• Workers use private Venice models, with web search, scraping, and model tool use disabled.
• Delivery protection stores only HMAC fingerprints and bounded state needed to redeem an interrupted delivery.

The optional USDC-to-DIEM treasury remains disabled in production and is not part of the storefront runtime. No wallet signer or private key is deployed to Vercel.

What is implemented

• Three Venice structured-output text workers with post-response JSON Schema validation
• Bounded Venice speech, image, and transcription workers
• Native Venice API-key compute ceiling of 1.69 DIEM per EPOCH (daily, resetting at 00:00 UTC)
• Atomic Upstash-backed software ceiling of 0.25 DIEM of conservatively reserved work per UTC day
• An environment-backed storefront kill switch checked before payment
• Input validation before payment, including exact PCM WAV duration checks
• Pre-payment Venice epoch-access, model-online, private-model, and capability checks
• Free machine-readable catalog and per-worker fixed-price quotes
• OpenAPI 3.1, llms.txt, A2A 1.0 Agent Card, JSON-RPC SendMessage, and Streamable HTTP MCP discovery
• x402 exact-price USDC payment gating through the CDP Facilitator
• Rich per-worker x402 Bazaar schemas, service name, topical tags, and service icon
• Official MCP Registry metadata for the public Streamable HTTP server
