fix(prompt): api.blockrun.ai is not an alias of the Base gateway - #168
Merged
Conversation
The gateway section handed the model this: - Base chain: https://blockrun.ai/api (alias: https://api.blockrun.ai) Those are different services. api.blockrun.ai authenticates a bearer key and 401s without one; blockrun.ai and sol.blockrun.ai answer a 402 challenge and ignore a key entirely. Told they are aliases, the model can send a wallet-signed request to a host that cannot settle it, or a key to a host that cannot read it, and the failure looks like a gateway bug rather than a routing mistake. The section was also unconditional, so it never said which host THIS session is on. It now names one: api.blockrun.ai for a key, sol.blockrun.ai/api for Solana, blockrun.ai/api for Base — plus which hosts are not yours and why, and an instruction not to switch billing modes to work around an API error. Found while auditing that: assembleInstructions' cache key carried the pay mode but not the chain. Both the gateway host and the wallet guidance name the active chain, so a base -> solana switch inside one process was served the previous chain's instructions. The key now carries the full billing identity. Request routing itself was already correct — no caller bypasses gatewayBase() and there are no hardcoded gateway hosts. This was the agent's own map being wrong, not the plumbing. Mutation-tested: restoring the alias line fails 3 tests, dropping the chain from the cache key fails 1. 756 local tests pass.
