Pay for throughput, never for correctness.
Two plans gate throughput, streaming and controls, but never decimals, the archive or the proof. Start on Pro and move to Scale when you hit a gate.
Then $49/month
Production Arc RPC, and every correctness API, for one backend.
- Complete JSON-RPC: eth, net, web3, txpool, debug, trace, arc
- Unpruned archive from genesis, billed at request parity
- Decimal-safe USDC balances and the Settlement Proof API
- Unified USDC transfer feed · 250 RPS · 400M requests
- 20 Gwei floor guard · 10 webhooks · 99.9% uptime target
Then $199/month
gRPC streaming, full backfill, and every warehouse sink.
- Everything in Pro
- gRPC and gRPC-Web streaming, with a signed gap report per range
- Compliance pre-flight against live blocklist state
- Full history backfill · 1,500 RPS · 2,000M requests
- Kafka, Postgres, ClickHouse and S3 sinks · 99.99% uptime target
Annual billing is 10× monthly, two months free on both plans. Every gate (throughput, streaming, sinks, controls, SLA) is spelled out in the full feature matrix.
Price yourself in.
Set your expected usage and get an estimated monthly bill plus the tier that fits. Published overage rates, no quote call.
Simultaneous gRPC subscriptions across your keys.
Delivered egress per day. Server-side address and kind filters are the lever. Subscribe narrowly and this number stays small.
Arc mainnet and testnet combined. Archive reads count the same as reads against the tip.
Estimates assume a 30-day month and published overage rates: $0.32/M requests, $0.06/GB stream egress.
Recommended tier: Pro
Estimate only. Your bill meters actual usage.
Every gate, in one table.
Tiers gate throughput, filter breadth, recent replay, RPC rate, and SLA. Raw financial fields retain their decimal representations on both plans; historical work is requested separately.

✓ included · — not included · ◑ partial, see notes
- debug: the four tracers that work on Reth: The Geth-era debug methods are registered on Reth but answer null. We list which ones, instead of selling them.
- arc_getVersion and arc_getCertificate: rpc_modules does not advertise the arc namespace. Providers disagree on whether arc_getCertificate accepts "latest"; ours does, and the docs list every error it can return.
- Unpruned archive, billed at request parity: At half-second blocks the 127-block archive boundary is about a minute old, so a multiplier would tax ordinary reconciliation.
- Decimal-safe USDC balances: Native 18, ERC-20 6 and the display value in one response, with a truncation flag.
- Unified USDC transfer feed: Both emitters merged and de-duplicated, with Memo, blocklist and CCTP legs attached.
- 20 Gwei floor guard: A transaction below the floor is rejected with an error instead of vanishing without a receipt.
- Compliance pre-flight (simulateTransfer): Answers whether a transfer will revert, and why, against live blocklist state.
- Snowflake, BigQuery, Redpanda, Kinesis: On request with Scale; included in Enterprise scope.
- Dedicated nodes and a custom endpoint domain: Available with Enterprise; see /enterprise.
- SOC 2 report: Type I in progress, Type II targeted Q2 2027. Marked roadmap.
Add-ons beyond the tiers.
One-time and standing purchases that don't need a tier change, priced per dataset, per request, or per node.
Billing, metering, and limits.
The questions buyers actually ask before adding a card. Anything missing lives in the docs, or ask us directly.
An RPC and data provider built for Arc, Circle's Layer-1 for stablecoin settlement. One API key covers JSON-RPC on mainnet 5042 and testnet 5042002, the unified USDC transfer feed, settlement proofs, gRPC streams and warehouse sinks.
Standard JSON-RPC is served well by many Arc providers. The differences are in Arc's own behaviour. When we tested public mainnet endpoints in September 2026, providers disagreed on whether arc_getCertificate accepts "latest", several pruned old state, and only one served debug and trace alongside full history. None of the providers we surveyed de-duplicates the two USDC emitters with Memo and CCTP attached, and none serves commit certificates by transaction hash. That is the product.
No. Standard JSON-RPC stays standard. Change the URL and the key; your client keeps working. The Arc-native methods are additions, not replacements.
No. Archive is on every plan and billed at the same rate as a call against the tip. At half-second blocks the usual 127-block archive boundary is about a minute old, so charging a multiplier would tax ordinary reconciliation.
Kafka, Postgres, ClickHouse and S3 are included on Scale. Snowflake, BigQuery, Redpanda and Kinesis are available on request.
ACTIVATE50 takes 50% off your first payment and is applied automatically at checkout: $24.50 for a first month on Pro, $99.50 on Scale. Renewals are at the standard price. Annual billing costs ten months for twelve.
Yes. Invoices can settle in USDC on Arc, the asset you already hold for gas. Card and bank transfer work too.
Yes, on Enterprise: isolated Arc execution and consensus nodes, a region of your choice, a custom endpoint domain and a signed SLA with credits.
Past self-serve? Get a node of your own.
Dedicated Arc execution and consensus nodes, private throughput, a custom endpoint domain and a signed 99.99% SLA. Available on annual contract.
Start on Pro. Upgrade when you hit a gate.
Production Arc RPC from day one, month-to-month billing. Scale is there when your throughput is.
