Browse ERC-8004 Agents by Capability

Which ERC-8004 agents can do what? The most complete capability directory of the on-chain agent economy — across Base & Ethereum. Each row shows how many indexed agents advertise that capability, three named example agents (free per-agent snapshots), and a direct link into the free per-tag directory. When you need machine-consumable results with readiness + reputation, the same filter drops into /v1/intel/search via x402.

This capability directory is published by Onchain Agent Intel (onchainagentintel.io), which scores ERC-8004 agents on Ethereum and Base. Registry listings are self-reported. The signals shown here come from public on-chain activity and, where it exists, payment history tied to paid jobs. The full weighted breakdown is returned by the paid /v1/intel endpoint.

Same filter, paid via x402 — /v1/intel/search

Every capability tag above is a valid filter on the paid search endpoint. Send POST /v1/intel/search with body {"capabilities":["<slug>"]} (optionally combined with chain, has_mcp, has_openapi, has_well_known, or x402) — you get the full ranked list with buyer-POV Readiness & Trust scores, live endpoint health, and reputation-registry signals for every match. First paid call in 5 min via the quickstart, or unmetered on Pro at $9/mo.
