Raydium API vs Helius: which one ships your trade in time?

The Raydium API and Helius solve different jobs. The Raydium API is a free REST endpoint that returns pool lists, prices, and farm metadata, and it polls. Helius is a paid Solana data provider whose LaserStream gRPC product delivers parsed Raydium swaps in real time. If you're building a chart, use Raydium's API and skip the rest of this page. If you're building a sniper, an arb bot, or anything where you can't miss the next slot, Helius is one option and there are two others worth knowing about.

Numbers as of April 2026. Helius cut data add-on prices about 20% on April 7, 2026, so the figures below reflect the post-cut tiers.

The pricing winner depends on volume. If your Raydium feed runs under 5 TB/month and you want webhooks, Helius is honest value. If your traffic is spiky (memecoin Tuesday) or you want predictable bills, flat wins. The Raydium API itself is free but doesn't compete on the same axis.

Pricing winner per use case: Raydium API for free dashboards. Helius for predictable enterprise volume with replay. NoLimitNodes for spiky bot traffic.

The Raydium API is a Cloudflare-fronted REST service that reads from indexers. Whatever number you see was true 5 to 30 seconds ago, depending on the polling cycle of the upstream indexer plus your own client poll interval. There is no push surface.

Helius LaserStream is Yellowstone gRPC with a fanout layer in front. Multiple Solana validator nodes feed into a regional aggregation tier; that tier hands you a slot-tracked stream that survives single-node failure. They publish ~15ms p50 from slot landing to your client, and they ship a Rust-NAPI JavaScript client that hits roughly 1.3 GB/s where naive Yellowstone JS hits 30 MB/s. The redundancy is real; the hop count is also higher than a direct gRPC connection.

Raw Yellowstone gRPC, including ours, sits closer to the validator. One hop, no aggregation tier, parsed events for AMM v4, CLMM, and CPMM. We measure 12ms p50 in us-east. You give up regional redundancy in exchange for a tighter loop.

Latency winner: NoLimitNodes (12ms) edges Helius (~15ms) on raw p50. Helius wins on multi-region failover and replay.

You want webhooks, not gRPC. Helius is the only major Solana provider that ships first-class enhanced webhooks for parsed program events. If you're running a Lambda or a Cloudflare Worker that fires per Raydium swap, the webhook posture is the right shape; gRPC is the wrong shape.

You need 24-hour replay out of the box. Reconnects happen. LaserStream tracks slots and lets you resume without writing your own buffer. That alone is worth the price for some teams.

You're running globally and want the closest endpoint of 9 regions to your workers. Frankfurt, Amsterdam, Tokyo, Singapore, Newark, Pittsburgh, Salt Lake City, Los Angeles, London. That's real coverage and it's honest of us to flag it.

Your traffic is steady and predictable. The data add-on tiers reward known volume. If you'll do 4 to 5 TB every month and never spike, the Pro plan plus the 5 TB add-on at $500 is reasonable.

You're building a chart, a leaderboard, or a portfolio dashboard, and 5-second freshness is fine. Then the official api-v3 is free, well-documented, and maintained by Raydium themselves.

You want the canonical pool list. The official API is the source of truth for which pools Raydium counts as official. Even if you stream events for execution, you might still hit api-v3 to enrich pool metadata.

You're prototyping and don't want to pay anyone yet. Combine the Raydium REST API with public Solana RPC logsSubscribe and you can ship a v0 over a weekend. You'll outgrow it within a month, but that's a future-you problem.

We sit between "free public Raydium API" and "LaserStream Pro plus add-ons." Parsed AMM v4, CLMM, and CPMM events over Yellowstone-compatible gRPC. 12ms p50. $49/month for two streams, $199/month for twenty. No per-event meter. The 10x price guarantee says we'll refund 10x the difference if you find a like-for-like quote that beats us.

We're honest about what we don't have. No webhook product yet. Single primary region today. Replay window is shorter than Helius's 24 hours unless you're on Ultra. If those matter more than price, Helius is the right answer.
