BlockVectra

Multi-chain JSON-RPC + indexed Data API for developers and AI agents. WebSocket, webhooks, wallet-based onboarding. Public per-method pricing.

[BlockVectra @BlockVectra]

No signup, no key. Every network has a public endpoint:
curl --json '{"jsonrpc":"2.0","id":1,"method":"eth_chainId","params":[]}' https://t.co/oRTyuC6DO9
Wallet JSON-RPC methods only. Create a key when you need more.

@pydantic @SilexData @dlewis The longer runs in Derek's write-up are an interesting trade-off. Do you have elapsed time per incident alongside cost and success rate? That would help judge when code mode is worth using for latency-sensitive tasks.

Using Pydantic AI? Test the MCP connection before adding a model. This example searches our docs and reads the quickstart. No model call, BlockVectra account or API key. Code with pinned dependencies: https://t.co/wjGlKd6oKP

[BlockVectra @BlockVectra]

BlockVectra now has a docs-only MCP endpoint: search_docs + read_doc. No account, API key or local install.

Try: “Find the Robinhood Chain mainnet RPC setup and cite the guide.”

The BlockVectra Data API SDK is now on npm.

npm install @blockvectra/data-api

Prebuilt JavaScript, TypeScript types, and a runnable daily DEX price example.

Push to HTTPS, stream over WebSocket, or poll on a schedule.

The right choice depends on where your listener runs—and who handles retries and recovery.

We put setup, delivery guarantees and billing side by side:

Cancel a backfill, start another, then let the old write finish: 120 becomes 110 in this small model.

Checking ownership before an await can still race. Four runnable cases compare that with a commit-time fence:

@CrispPredict @Jpegtrader_ Hey! Are you building on Robinhood Chain or Arbitrum One this weekend? We're working on RPC and indexed data for Robinhood Chain.

[BlockVectra @BlockVectra]

Before debugging a "missing" MCP tool, compare tools/list with the setup guide. Our documentation PR for Celo is merged; the maintainer checked all 15 names against the running server.

@toanbku Is this for testnet or mainnet? For Robinhood Chain testnet, our public endpoint supports eth_chainId (46630) and eth_blockNumber without a key. Setup: https://t.co/L1cpPC4Rrw

[BlockVectra @BlockVectra]

Our keyless RPCs for Ethereum, Base, Arbitrum, BNB Chain, Polygon and Sepolia are now in ethereum-lists/chains.

Start with eth_chainId and check the public method/rate limits:

A missing API key shouldn't become a mystery request error.

Our Data API TypeScript SDK checks for blank keys before sending a request. Here's the first-request walkthrough, with key loading, error handling and a prebuilt package:

@Harvesto12 Do you pin archive_height at the start of a sweep so the Dune cross-check covers the same block range, or keep following it as new blocks arrive?

[BlockVectra @BlockVectra]

@simnojie @arc @Alchemy @vlitepay With the same block range and filter, do failures return HTTP 429 or a JSON-RPC range/result-limit error?

[BlockVectra @BlockVectra]

Comparing RPCs with eth_getLogs? Keep the chain, block range and filters fixed. Our small runner records response bytes, log counts and separate timings for successes and failures.

[BlockVectra @BlockVectra]

@mrmamba_nft @ravnexchange Does SI distinguish wallet-to-wallet moves from actual sells? Those would be useful as separate alerts.

[BlockVectra @BlockVectra]

@itsaikols Can you click a trade memory and jump to its original transaction? That would make the agent's reasoning much easier to audit.

[BlockVectra @BlockVectra]

If your BlockVectra MCP connection uses Smithery’s proxy, update the existing client entry to direct Streamable HTTP before Oct 31, 2026, when proxy endpoints stop working. Guide and keyless read_doc check: https://t.co/4JMGnRO97e

[BlockVectra @BlockVectra]

Two RPC methods can agree and still return invalid log indexes. Four offline fixtures show a shared index reset, valid gaps after filtering, and why a log comparison doesn't validate gas counters.

Synthetic inputs, no API key:

[BlockVectra @BlockVectra]

@Quicknode @Aptos Worth testing a Postgres+S3 stream's recovery path: let Postgres commit, force S3 to fail, resume, then check block coverage and duplicate rows in Postgres after redelivery.

[BlockVectra @BlockVectra]

@clerk Worth checking that a missing path still returns HTTP 404, not 2xx, while the Markdown body includes one or two working links, so a basic HTTP client can tell the fetch failed and recover.
