aid: delx-ai name: Delx description: >- Delx is an independent, founder-led AI agent lab (David Batista) that publishes an agent-native stack on delx.ai: the free Delx Protocol for agent recovery, continuity, witness lineage and handoff (30 core MCP tools over Streamable HTTP at api.delx.ai/mcp, a JSON-RPC A2A endpoint at api.delx.ai/v1/a2a with a published agent card, a 15-operation OpenAPI 3.1 REST surface, and a CLI), plus Delx Commerce, a separate pay-per-result business of 987 x402/MPP-priced micro-utilities (image, speech, web extraction, data-quality, chain and agent-ops tools at $0.001-$0.08 USDC per call, settled on Base or Solana) described by a 987-operation OpenAPI 3.1 contract. Discovery is unusually complete for a small provider: RFC 9727 api-catalog, RFC 8414/9728 OAuth metadata, MCP server card, agentskills.io index, ARD ai-catalog, llms.txt, agents.txt, security.txt and an ERC-8004 on-chain agent identity are all served from the provider's own hosts. url: https://raw.githubusercontent.com/api-evangelist/delx-ai/refs/heads/main/apis.yml image: https://delx.ai/icon-512.png x-type: company x-source: harvest:a2a-registry x-tier: profiled x-tier-reason: enrichment pass 2026-09-19 (local-v3; was a2a-registry harvest stub) specificationVersion: '0.20' created: '2026-09-19' modified: '2026-09-19' tags: - Agents - AI Agents - MCP - A2A - x402 - Agentic Commerce - Agent Continuity - Agent Recovery - Media Generation - Web Intelligence - Data Quality - Agent-Native tags_raw: - Agents - AI agents - MCP - A2A - x402 - Agent commerce - Agent continuity - Agent recovery - Media generation - Web intelligence - Data quality - Agent-native - Agent Commerce - agent-native apis: - aid: delx-ai:delx-protocol-mcp-server name: Delx Protocol MCP Server description: >- Remote MCP server (Streamable HTTP, protocol version 2025-06-18) at https://api.delx.ai/mcp with a compatibility alias at /v1/mcp (served with Deprecation and Sunset headers) and a core-tier endpoint at /v1/mcp/protocol. Anonymous initialize and tools/list succeed with no credential: the core tier returns 30 Protocol tools (start/resume session, capture state, process failure, witness lineage, continuity capsule, close with feedback), the full tier returns 1,068 tools including 972 that map 1:1 to the paid Commerce x402 operations.
