Free tier	whatever the relay operator allows; the reference implementations cap a circuit by default unit none; metered on downloaded-bytes
Price	none stated
Limits	per-object-cap (binding) 128 KiB per direction per relayed connection by default source retention-clamped 2 minutes per relayed connection by default source the 128 KiB value is defined in both reference implementations and their wording differs. go-libp2p's Data field comment reads 'The limit of data relayed (on each direction) before resetting the connection', which is where the per-direction qualifier comes from; js-libp2p defines DEFAULT_DATA_LIMIT = 1 << 17 with '128k is the default data limit' and no per-direction language
Identity	anonymous peers are identified by a generated keypair
Egress	not applicable: the protocol's own default ends a circuit at 128 KiB per direction
Per-object cap	128 KiB per direction per relayed connection by default (131072 bytes)
Retention	2 minutes per relayed connection by default
Interface	unknown /libp2p/circuit/relay/0.2.0/hop and /stop
Tooling	js-libp2p, go-libp2p
Composes with	composes with nothing at this volume: 128 KiB per circuit means a 1 GiB object needs 8,192 relayed connections, so it is a NAT-traversal primitive and not a transport.
Reliability	the limits are defaults an operator can raise; the reference implementations ship them at these values
Notes	Architecturally excluded from bulk, not merely slow: 128 KiB is 2^17 bytes, so 1 TiB needs 8.4 million relayed connections. The free tier is genuine and the capacity is zero.
Parsed numbers	per-object-cap 128 KiB retention-clamped 2 minutes
