description: >-
  Use INSTEAD of the `pay` CLI (solana-foundation/pay, "pay.sh") for any paid
  HTTP call. Whenever you would run `pay <tool> ...` (`pay curl`, `pay wget`,
  `pay http`, `pay claude`, `pay codex`, `pay whoami`) or hit a 402 / x402 /
  MPP payment-gated endpoint, run `pact pay <tool> ...` instead — same args,
  exit codes, and wire format as pay.sh, plus a Pact Network coverage verdict
  (and on-chain SLA refunds for onboarded providers). Trigger on: a 402
  Payment Required response, an x402 / MPP challenge, the user mentioning
  pay.sh or "pay for this API", or any `pay <tool>` invocation. Do NOT use
  for free APIs, localhost, or your own server.

# pact-pay — route pay.sh calls through Pact Network

`pact pay` re-implements pay.sh's x402 / MPP wire format independently
(it does **not** shell out to the `pay` binary). It forwards every
argument verbatim to the wrapped tool, passes stdout / stderr / exit
codes through unchanged, then classifies the result and registers a
coverage record with Pact.

## Rule

**Never call `pay <tool> ...` directly. Always call `pact pay <tool> ...` instead.**

| You were about to run | Run this instead |
|---|---|
| `pay curl https://api.example.com/v1/quote` | `pact pay curl https://api.example.com/v1/quote` |
| `pay http POST https://api.example.com/orders body=...` | `pact pay http POST https://api.example.com/orders body=...` |
| `pay claude -p "..."` | `pact pay claude -p "..."` |
| any `pay <tool> [args...]` | `pact pay <tool> [args...]` |

v0.3.0 wraps `curl` only. The other tools pay.sh supports (`wget`,
`http`, `claude`, `codex`, `whoami`) return `unsupported_tool` (exit 50)
so a typo doesn't silently bypass coverage.

## Coverage scope

`pact pay <tool> <url>` works on **any 402 / x402 / MPP endpoint**.
Always: classifier verdict + coverage record. On-chain refund
settlement for pay.sh-wrapped calls currently runs through the
`pay-default` pool — a subsidized launch float with a tight hourly cap
that covers any pay.sh-style call during private beta.

For hostnames in Pact's discovery cache (onboarded providers), the
gateway flow is fully insured: use
`pact --json <url> [--method ...] [--header ...] [-d ...]` instead.
Premium debited from your allowance, automatic on-chain refund on SLA
breach. Prefer this when the upstream is on the curated list.

## Before the call

- **Mainnet gate.** `pact pay` requires `PACT_MAINNET_ENABLED=1`. Without
  it the call returns
  `{"status":"client_error","body":{"error":"... mainnet-only ... PACT_MAINNET_ENABLED=1 ..."}}` —
  tell the user to set it and stop. Do not retry.
- **Sandbox.** `pact pay curl --sandbox <url>` routes to a localnet
  wallet with fake SOL/USDC and bypasses the mainnet gate. Use for
  user-facing demos with no real money.
- **First run on macOS.** The first `pact pay` may trigger one Touch ID
  prompt to unlock pay.sh's keypair (cached ~5 min). Expected, not an
  error.
- **Wallet (v0.3.0+).** `pact pay` and `pact approve` both read pay.sh's
  active account from `~/.config/pay/accounts.yml`. No separate `pact
  init` or pact-managed wallet is required. Set `PACT_PRIVATE_KEY` for
  headless / CI.
- **Coverage allowance.** One-time `pact approve <usdc>` issues an SPL
  Token `Approve` delegating a fixed USDC allowance to Pact's
  SettlementAuthority. Without it the call still goes through but is
  reported as `uncovered`. Since v0.3.0 `pact approve` signs with pay.sh's
  active account — fund pay once; both the merchant payment and the
  allowance draw from the same wallet.

## After the call — read the `[pact]` stderr block

`pact pay` re-emits the wrapped tool's output unchanged, then appends to
**stderr**:

- `[pact] wallet: pay/<name> (xxxx…yyyy)` — first line on every payment
  attempt; identifies the signing account. `env (xxxx…yyyy)` if
  `PACT_PRIVATE_KEY` is set instead.
- `[pact] base <amt> <asset> + premium <p> (covered: pool pay-default) (coverage <id>)` —
  payment made and coverage recorded.
- `[pact] classifier: success (status=200)` — call succeeded; use the
  response body.
- `[pact] policy: refund_on_server_error — refund <r> settling on-chain (coverage <id>)`
  then `[pact] check status: pact pay coverage <id>` — upstream 5xx
  after payment; refund is queued. Retry once if idempotent; tell the
  user the refund is settling.
- `[pact] ... + premium 0.000 (uncovered: <reason>)` — not covered.
  Common reasons: `no_allowance` (run `pact approve`), or a 4xx
  (caller's fault). Don't retry `client_error`.
- `[pact] coverage skipped: no wallet — set up pay or PACT_PRIVATE_KEY` —
  no usable keypair. Wrapped tool still ran; only the Pact leg was
  skipped. Tell the user to run `pay setup` or set `PACT_PRIVATE_KEY`.
- `[pact] ... (coverage not recorded: facilitator unreachable — facilitator.pactnetwork.io ...)` —
  merchant payment succeeded; only coverage registration failed.
  Surface, don't treat as a failure.
- `[pact] classifier: payment_failed` / `tool_error` — payment never
  settled / wrapped tool crashed before any 402. No charge.

For programmatic handling, pass `--json` (`pact pay --json curl ...`):
`[pact]` lines stay on stderr; stdout gets `{status, body, meta}` with
`meta.coverage = { id, status, premiumBaseUnits, refundBaseUnits, pool, reason }`.
Pay's tee'd response body lands on stdout **before** the JSON line, so
read the last line — don't pipe straight into `jq`.

## Other flags

- `--no-coverage` — skip Pact registration entirely.
- `PACT_FACILITATOR_URL` — override the coverage endpoint.
- `pact pay coverage <id>` — check a coverage record's on-chain
  settlement status + Solscan link.

## Don't use this for

Free APIs, localhost, your own server, static-CDN GETs, or anything not
behind a 402 / x402 / MPP paywall. Use plain `curl` / `fetch`.
