eth_getBlockByNumber

Return a block by number or tag.

Base mainnet, chain ID 8453base:rpcfree — enforced matrix policy, not measured capacity or runtime publicationAvailability: unknownValidation: positive_fixture

Parameter limits

JSON path	Frozen limit	Source
—	`unknown`	No numeric parameter ceiling is frozen; enforce the declared schema shape and deny an unknown oversized/range profile.

Historical block retrieval is not an archive-state guarantee. Selectors must be preserved; do not substitute pending, safe, or finalized with latest.

Rate limits and tier

These are enforced product-policy values, not measured upstream capacity or an SLA. Enterprise is finite, never physical “unlimited” capacity.

Tier	Limit / access	Category
Free	10 RPS	base_read_rpc
Basic	20 RPS	base_read_rpc
Pro	100 RPS	base_read_rpc
Business	250 RPS	base_read_rpc
Enterprise	250 RPS	base_read_rpc

See Base limits.

Errors

Code	Meaning here	Client action
`-32602`	Parameters fail the declared schema or upstream parser.	Fix the positional parameters; parser acceptance is not execution success.
`-32003`	The enforced category/provider budget is exhausted.	Honor `Retry-After`; no capacity SLA is implied.

Authentication/transport failures use the shared client error envelope. See Base errors.

Evidence

Fixture kind: positive_fixture.
Fixture source: infra-4-sety/integration-base/research/R04/measurement/FIXTURES.json at /fixtures/3.
Fixture SHA-256: eaef6dd7f176296a03d46f351e0378a8ea073e39d53f9ab49e256f69048b3e66.
Fixture registry: infra-4-sety/integration-base/research/R04/measurement/FIXTURES.json.
Semantic assertion: non-null sealed block header with number/hash/parent/stateRoot/timestamp and hash transactions
Source UTC: 2026-09-08T13:27:42.173Z.
Evidence boundary: only the frozen fixture assertion is reusable; it is not blanket provider or deployment evidence.

Limitations

Availability is the frozen baseline, not deployed readiness. documented is the contract floor; evidence_kind retains unknown/source_summary.
