blockrun

# BlockRun One wallet, pay-per-call, no API keys. Every paid tool below settles in USDC over x402 at the moment of the call. ## Never quote a price from memory There is no price table in this skill, and that is deliberate. Every flat per-call price published in this repo drifted by exactly the per-transaction fee the last time that fee changed, because each one was a typed copy. Read prices from a live source instead: | Need | Where | |------|-------| | Per-token model pricing | `blockrun_models` | | What a call will actually cost | the `402` response — it carries the real amount | | Full endpoint catalog with prices | <https://blockrun.ai/llms.txt> (Base) · <https://sol.blockrun.ai/llms.txt> (Solana) | The tool descriptions in the MCP server carry the published base prices too; they are typed by hand and verified against live 402 quotes by `npm run verify:prices`, and the 402 header is what actually gets charged. ## The two chains are not the same gateway `blockrun.ai` and `sol.blockrun.ai` are separate deployments, and `blockrun_wallet action: "chain"` switches between them mid-session. Two consequences, both easy to miss because nothing announces the switch: **Prices differ, on purpose.** Every figure in these skills is the **Base** price. Base adds a flat per-transaction fee; Solana deliberately adds none — the ~$0.001-per-call gap is pricing policy (an incentive to settle on Solana), not drift, so do not expect it to be "fixed".
