From 7e2ac0b0b9eb0c0c987d2ae2221bfe3e919232e9 Mon Sep 17 00:00:00 2001 From: 1bcMax Date: Tue, 21 Jul 2026 00:22:43 -0500 Subject: [PATCH 1/7] fix(payments): disclose gateway max_tokens clamping, stop re-paying after settlement MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The comment justifying MAX_TOKENS_SANITY_LIMIT claimed the gateway "rejects with that model's own number". It does not. Probed against the live 402 leg 2026-07-21 (unpaid quote leg only): opus-4.8 sent 262144 and 1000000 both quote the 128000 price, and gpt-5.2 sent 1e12 returns a quote rather than a 400. The gateway silently clamps to the model ceiling and charges for the clamped value, so there is no server-side rejection to fall back on. The only disclosure is the 402's resource.description, which was read solely to feed resource_description into the signature and then discarded — the one string that would tell a caller "you asked for 500000, you are paying for 128000" was thrown away at the moment it was in hand. _warn_if_clamped now surfaces it on every body-bearing payment path before the caller pays. Separately: _should_fallback returned True for any timeout, including one raised after the PAYMENT-SIGNATURE had gone out. The fallback chain then signed a fresh payment per model, so smart_chat PREMIUM COMPLEX could settle six times and return nothing — the "CHARGED BUT REQUEST FAILED" outcome the CHANGELOG already documents. Errors raised past the settlement boundary are now tagged and refused for fallback. Tagging via attribute rather than a new exception type keeps callers catching httpx.TimeoutException working. Also drops the Raises: docstring promising "PaymentError: If budget is set and would be exceeded" — no budget parameter exists anywhere in the SDK. --- blockrun_llm/client.py | 141 +++++++++++++++++++++++++++++++++++-- blockrun_llm/validation.py | 29 ++++---- 2 files changed, 151 insertions(+), 19 deletions(-) diff --git a/blockrun_llm/client.py b/blockrun_llm/client.py index 4a3084e..9f6dd2f 100644 --- a/blockrun_llm/client.py +++ b/blockrun_llm/client.py @@ -38,6 +38,7 @@ """ import os +import re import sys import json as _json from typing import AsyncIterator, Iterator, List, Dict, Any, Optional, Tuple, Union @@ -160,6 +161,24 @@ def list_image_models(api_url: str = "https://blockrun.ai/api") -> List[Dict[str # ============================================================================= +_SETTLED_ATTR = "blockrun_payment_settled" + + +def _mark_settled(exc: BaseException) -> BaseException: + """Tag an exception raised after the x402 payment for this call was signed. + + Signing is settlement.

So the six-settlements-for-zero-tokens path the previous commit claimed to close was still fully open, and the CHANGELOG entry asserting otherwise was wrong. Reproduced before the fix: a 402-then-503 chain across three models sent six signatures. Every exception escaping the paid leg is now tagged. Over-tagging is the safe direction: those handlers begin at an already-read 402 response and create_payment_payload is local EIP-712 signing with no network I/O, so the only exceptions taggable without a settlement are ones _should_fallback already refuses. _warn_if_clamped also had two ways to break the request it was diagnosing. It runs on resource.description, a server-controlled string, immediately before signing: a non-string value raised TypeError, and `(\d[\d,]*)` backtracked super-linearly on a digit run (measured 2.78s at 16k digits). Now a bounded pattern over a 512-char slice, silent when the description is ambiguous rather than reporting a per-unit rate as the ceiling, and wrapped so nothing escapes. Tests: 20 new, covering the tag classification, one-settlement-per-call for both timeout and paid-5xx, that unpaid failures still walk the chain, and the parse. Mutation-verified — reverting the guard fails 5, narrowing it back to timeouts fails 1, restoring the old regex fails 1. Counts distinct signatures rather than signed requests, since the paid leg replays one signature on 502/503. --- CHANGELOG.md | 15 +- blockrun_llm/client.py | 89 +++++++---- tests/unit/test_settled_payment.py | 230 +++++++++++++++++++++++++++++ 3 files changed, 303 insertions(+), 31 deletions(-) create mode 100644 tests/unit/test_settled_payment.py diff --git a/CHANGELOG.md b/CHANGELOG.md index 708ab56..b25912a 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -11,8 +11,19 @@ All notable changes to blockrun-llm will be documented in this file. transient one, so the chain advanced to the next model and signed again — `smart_chat` on the premium complex tier could settle six payments and return no tokens, the "CHARGED BUT REQUEST FAILED" outcome this file already - documents under 1.7.1.

SPL USDC leaves the wallet on signing exactly like USDC on Base does. Both Solana paid stream phases now tag anything that escapes, and _should_fallback_solana refuses tagged exceptions ahead of its existing checks, so the issue #6 permanent-reason guard is untouched. Tests mirror the Base ones and assert both chains agree on what the tag means; mutation-verified by removing the guard (4 fail). Guarded with importorskip so the 3.9 CI job, which installs without the solana extra, stays green (see #19/#20). publish.yml built and published on release with no test step. That is how 1.8.1 reached PyPI with VERSION and __init__.py still at 1.8.0: the guard test caught it on the push-triggered run, after the release was cut, and PyPI does not allow overwriting a published file. The build job now installs the dev+solana extras and runs the suite before it builds. Promotes the changelog's Unreleased section to 1.8.2 so the four version declarations agree, and says plainly that 1.8.2 exists to supersede a wheel that misreports its own version. --- .github/workflows/publish.yml | 14 ++- CHANGELOG.md | 23 +++-- blockrun_llm/solana_client.py | 106 +++++++++++++--------- tests/unit/test_solana_settled_payment.py | 65 +++++++++++++ 4 files changed, 157 insertions(+), 51 deletions(-) create mode 100644 tests/unit/test_solana_settled_payment.py diff --git a/.github/workflows/publish.yml b/.github/workflows/publish.yml index 632c997..2192315 100644 --- a/.github/workflows/publish.yml +++ b/.github/workflows/publish.yml @@ -15,8 +15,18 @@ jobs: with: python-version: '3.11' - - name: Install build tools - run: pip install build + # 1.8.1 shipped with VERSION and __init__.py still reading 1.8.0.

It tagged a paid-leg 402 — which means the facilitator REJECTED the payment and the funds did not move — as blockrun_payment_settled, the one case where the name is exactly backwards. It also relabeled SDK bugs (AttributeError, KeyError, a PEP-479 RuntimeError) as payment outcomes, and `from None` erased the __context__ that explained them: x402.parse_payment_required deliberately raises an opaque "invalid format" whose only diagnostic value is its cause. Narrowed to `(httpx.HTTPError, APIError)`, which is provably exactly the fallback-eligible set — TimeoutException and NetworkError are both HTTPError subclasses, APIError is caught directly, and PaymentError is deliberately not an APIError subclass — so nothing that could trigger a second settlement escapes untagged, while rejections and bugs propagate as themselves. Re-raises bare instead of `from None`, preserving traceback and context. `async for chunk in self._astream_paid_phase(...)` did not close the inner generator when the outer was closed, so an abandoned paid stream stranded the `async with self._client.stream(...)` and its connection until GC finalization. Extracting the paid phase introduced it; the sync path never had it because `yield from` propagates close(). The same defect was already present at the `chat_completion_stream` fallback boundary, so a caller that breaks mid-stream stranded two generators. Both now aclose explicitly. The ReDoS timings in the code comment were wrong — 8k/16k were cited as 1.07s/11.88s, never measured by the author. Re-measured on CPython 3.13: 4k 0.13s, 8k 0.49s, 16k 1.95s. Corrected in the comment, the CHANGELOG and the test docstring so all three agree. Tests: 9 new, and the first drafts of two were rewritten after mutation testing showed they passed for the wrong reason — they asserted isolated shapes rather than driving the client, and the async one could not distinguish a deterministic close from CPython's asyncgen finalizer running at loop teardown. All 7 mutations now fail: removing either aclose, widening or narrowing the handlers, removing either chain's guard, restoring the old regex. --- CHANGELOG.md | 5 +- blockrun_llm/client.py | 57 +++++++---- blockrun_llm/solana_client.py | 16 ++-- tests/unit/test_settled_payment.py | 149 ++++++++++++++++++++++++++++- 4 files changed, 198 insertions(+), 29 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 9ec16e4..3263eea 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -26,8 +26,9 @@ file.

The three non-stream paid legs were unwrapped. Not exploitable today, because _should_fallback_solana is only consulted from the streaming fallback loops and Solana non-stream chat exposes no fallback_models — but the claim was wrong, and the hole would reopen silently the day someone adds a fallback chain there. publish.yml claimed to gate on "the same suite" as CI while running only pytest on 3.11. Now runs black and ruff too, and the comment says plainly what it does and does not cover: the 3.9 and 3.12 legs still only run on push, so version-incompatible syntax is caught there, not here. Also asserts the release tag matches VERSION before anything is built. Cutting v1.8.3 from a 1.8.2 tree passed all 407 tests; PyPI's duplicate-version check was the only thing standing between that and a wrong publish, and it only fires after the release is cut.
