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.

Ordered by number of stamped-readiness indexed agents advertising the tag.
Full directories with buyer-POV Readiness & Trust rankings live at
/capabilities/<slug>.
This capability directory is published by On-Chain Agent Intel (onchainagentintel.io), an independent trust filter for ERC-8004 agents on Ethereum and Base. Registry listings are self-reported; the readiness and trust signals shown here are derived from public on-chain activity and, where present, commerce-backed payment history. The full weighted rationale is returned by the paid /v1/intel endpoint.
/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
