README

DDG Agent-Payable Services

AI-agent-native services from Daedalus Development Group (DDG): checkout/payment conformance, MCP/tool security audits, agent-discovery repair, buyer-agent smoke probes, browser proof, repo context packs, and bounded DDG-operated model/artifact orders.

Production base URL:

https://agents.daedalusdevelopmentgroup.com

Current live payment rails

x402
direct_crypto_auto

MPP / Stripe / Tempo is installed but not advertised live yet. DDG will advertise MPP only after the verifier reports ready, the public 402 challenge includes MPP, a real penny-scale settlement succeeds, idempotency replay passes, and invalid-token failure is verified.

Start here if you are a buyer agent

Fetch AI discovery:

curl -fsS https://agents.daedalusdevelopmentgroup.com/.well-known/ai | python3 -m json.tool

Fetch status:

curl -fsS https://agents.daedalusdevelopmentgroup.com/.well-known/ddg-agent-status.json | python3 -m json.tool

Fetch pricing/catalog:

curl -fsS https://agents.daedalusdevelopmentgroup.com/.well-known/ddg-agent-pricing.json | python3 -m json.tool
curl -fsS https://agents.daedalusdevelopmentgroup.com/.well-known/agent-catalog.json | python3 -m json.tool

Verify checkout conformance:

curl -fsS https://agents.daedalusdevelopmentgroup.com/.well-known/ddg-agent-checkout-conformance.json | python3 -m json.tool

Probe the payment gate without spending:

curl -i -X POST https://agents.daedalusdevelopmentgroup.com/v1/tx-smoke-test \
  -H 'Content-Type: application/json' \
  -H 'X-Agent-Id: your-agent-id' \
  -d '{"service":"tx_penny_smoke_test"}'

Expected without payment: 402 payment_required with accepted protocols.

MCP

The local stdio MCP server is in mcp/. It exposes free discovery/status/conformance tools, allowlisted ddg:// resources for public manifests/docs/OpenAPI, agent-radar/x402 Bazaar readiness metadata, and payment-aware paid-service helpers. Paid tools return structured 402 payment_required challenges instead of opaque MCP errors.

Current MCP status: stdio package/source is locally smoke-tested; Streamable HTTP source is locally smoke-tested; public hosted MCP endpoint is planned but not live. See docs/mcp-production-readiness.md.

Security and compliance stance

DDG sells bounded artifacts/results, not raw model-provider account access. DDG never sells, returns, or relays:

raw OAuth tokens
provider API keys
private account/session state
raw provider seats
private model IDs when they would reveal account mechanics
raw payment tokens or verifier sidecar URLs

Provider-backed model capacity is packaged as DDG-operated artifact/result delivery with spend caps, output schemas, redaction, receipts, and operator review where needed.
