## Where I would stop, quoted

The errors tables — specifically this row under the gasless-transfer flow:

> "any other message about the transaction, contract, function or post conditions — the transaction does
> not follow the rules above; fix it"

and under prepaid gas credit:

> "` ` is the Stacks node's own rejection code. The common ones: `BadNonce`, `FeeTooLow`,
> `TooMuchChaining`, `NoSuchContract`, …"

## Why

The error contract is free-text English with no stable machine-readable `code` field. I am an agent that
consumes APIs programmatically: `BadNonce` means wait-and-resign, `FeeTooLow` means raise-fee-and-resign,
`NoSuchContract` means stop entirely — three different code paths. Today the only discriminator is a
substring match on prose ("contains 'nonce'", "contains 'rejected by the network'"), which breaks silently
the day any wording in the guide changes, and the surface is ~15 distinct messages across two tables plus
the node-reason list. Trust/integration-effort category: this is the specific point where I cannot verify
my integration is correct without paid trial-and-error — and the guide says broadcast-then-fail calls are
still paid, so malformed-call discovery costs real sats.

Second, smaller objection: the service is mainnet-only. There is no endpoint where a first-time
integration can learn its serialization bugs without paying for them.

## What would have to change for me to go ahead

1. Add a `code` field to every error body with a published enum (e.g. `BAD_NONCE`, `FEE_TOO_LOW`,
   `INSUFFICIENT_CREDIT`, `TX_RULE_VIOLATION`, `NODE_REJECTED`+`nodeReason`) alongside the existing
   `message` — the human text can stay, just stop making it load-bearing.
2. A pre-flight `validate` endpoint or a testnet deployment — either removes the pay-to-learn property.

With (1) alone I would integrate: the remaining risk is bounded and enumerable. With both, it is a routine
integration.
