How a failing token affects the retry. strict (the default, and the bare-string behavior): a failing redemption is a 400 and the retry is not served. best_effort: the retry is served either way — a token-layer failure no longer rejects the request; the retry proceeds at normal price and the outcome is reported on the response's usage.fallback_credit. Two failures stay hard in both modes: a malformed token, and combining fallback_credit_token with fallbacks.

?list<BetaIterationsUsageItem> iterationsPer-iteration token usage breakdown.
Per-iteration token usage breakdown.
Each entry represents one sampling iteration, with its own input/output token counts and cache statistics, discriminated by type. For message entries (model sampling iterations, such as the turns of a server-side tool use loop), this allows you to:
- Determine which iterations exceeded long context thresholds (>=200k tokens)
- Calculate the context window size from the last
messageentry - Understand token accumulation across server-side tool use loops
A compaction entry reports the token usage of the compaction operation itself — the server-side request that summarizes the context being closed — NOT the size of the context that was compacted away, and its token counts can be much smaller than that closed context (for example, a compaction that closes a ~200k-token context can report only a few thousand tokens). Do not derive the context window size from a compaction entry, even when it is the last entry. A compaction entry's tokens are not included in the top-level usage fields. When an input-token trigger is in effect (the default — 150,000 tokens unless configured otherwise), each compaction entry closes a context that had reached at least that threshold, though the context can exceed it by the final iteration's output and tool results.

BetaMessageDeltaUsage usageBilling and rate-limit usage.
Billing and rate-limit usage.
Anthropic's API bills and rate-limits by token counts, as tokens represent the underlying cost to our systems.
Under the hood, the API transforms requests into a format suitable for the model. The model's output then goes through a parsing stage before becoming an API response. As a result, the token counts in usage will not match one-to-one with the exact visible content of an API request or response.
For example, output_tokens will be non-zero, even for an empty string response from Claude.
Total input tokens in a request is the summation of input_tokens, cache_creation_input_tokens, and cache_read_input_tokens.
?list<BetaInputTransformation> inputTransformationsChanges the API made to the request's input before showing it to the model,

(the conversation before it differs from the one it was created in, or it
carries no record of one on a model that requires it) and was shown to the

The retry is sent either with the same request body (system, messages,
tools, and other render-shaping fields), or with the same body plus one
appended assistant message whose content is the partial text (with any
trailing whitespace stripped from the final text block) and paired
server-tool blocks from this refusal — which also authorizes that
appended turn as an assistant-prefill continuation on models that otherwise
disallow prefill. A token minted mid-server-tool-loop whose partial content
was continuable may only be redeemed the second way — if a same-body retry
is rejected with a 400 saying the token must be redeemed by continuing the
partial response, retry the second way instead. Either way: same workspace,
same platform; a mismatch is a 400. Resending a token for an already-warm
prefix is permitted but yields no additional credit.
null when the refused model isn't eligible for a fallback credit.
?bool fallbackHasPrefillClaimWhether the accompanying fallback_credit_token may be redeemed with the

Whether the accompanying fallback_credit_token may be redeemed with the
appended-assistant retry form. Only set when fallback_credit_token is
present.
true: retry by resending the same request body plus one appended
assistant message whose content is this response's content with any
trailing whitespace stripped from the final text block and unpaired
tool_use blocks omitted (the same appended-turn shape described on
fallback_credit_token), with the token attached. false: retry by
resending the original request body unchanged, with the token attached —
the appended-assistant form is not available for this refusal (no
continuable partial content, or the request uses output_format or a
tool_choice that forces tool use). One exception: when the request used
output_format or a forced tool_choice and the refusal arrived after
server tools (including MCP connector tools) had already executed, the
token may not be redeemable by either retry form; if the exact-body retry
is then rejected with a 400 saying the token must be redeemed by
continuing the partial response, discard the token and retry without it.
Advisory: if an appended-assistant retry is rejected with a 400 despite
true, fall back to resending the original request body with the token.

class BetaThinkingBlockParam { $type = 'thinking'; $signature; $thinking; }
string signatureThe signature value of this thinking block, exactly as returned by the API in a previous response. Used to verify that the block was generated by Claude.
The signature value of this thinking block, exactly as returned by the API in a previous response. Used to verify that the block was generated by Claude.
Thinking blocks must be passed back unmodified and in their original order; a modified block results in a 400 invalid_request_error.
The thinking text of this block as returned by the API.
class BetaThinkingConfigAdaptive { $type = 'adaptive'; $blockBinding; $display; }
Controls for block binding: what happens when a thinking block this request sends back fails the conversation check. Every field is optional; an empty object means every default.
Controls how thinking content appears in the response. When set to summarized, thinking is returned normally. When set to omitted, thinking content is redacted but a signature is returned for multi-turn continuity. Defaults to summarized.
class BetaThinkingConfigDisabled { $type = 'disabled'; }
class BetaThinkingConfigEnabled { $type = 'enabled'; $budgetTokens; $blockBinding; $display; }
int budgetTokensDetermines how many tokens Claude can use for its internal reasoning process. Larger budgets can enable more thorough analysis for complex problems, improving response quality.

class BetaThinkingConfigParam
class BetaThinkingDelta { $type = 'thinking_delta'; $estimatedTokens; $thinking; }
Per-frame increment of a coarse, running estimate of the tokens this thinking block has produced so far. Present whenever the thinking-token-count-2026-05-13 beta is set; null unless thinking.display resolves to "omitted" and a count is due this frame. Sum the increments across thinking_delta frames on this block for a progress indicator. Each increment is a non-negative multiple of a fixed quantum and the cadence is rate-limited, so this is a deliberately lossy display hint, not a billable count; usage.output_tokens remains authoritative.
The incremental thinking text for this content block. Concatenate the thinking values of successive thinking_delta events to assemble the block's full thinking value.
class BetaThinkingDroppedInputTransformation { $type = 'thinking_dropped'; $path; $reason; }
Always thinking_dropped for this entry type.
Where the removed block was in your request, as messages.{i}.content.{j}:
i indexes the messages array you sent and j that message's content
array — the same form error messages use.
Which binding check removed the block: model_binding_mismatch — it was
created by a model whose reasoning the requested model may not read;
prefix_binding_mismatch — the conversation before it differs from the
conversation it was created in (the rest of that turn's consecutive thinking
blocks are removed with it, each with this reason);
organization_binding_mismatch — it was created under a different
organization (an Anthropic organization, AWS account or Google Cloud project)
and this organization is not one of its additional organizations;
end_user_binding_mismatch — it was created for a different end user, or
was removed by the consumer-organization binding. A block that would fail
several checks reports one reason, in this order of precedence:
organization_binding_mismatch, end_user_binding_mismatch,
model_binding_mismatch, prefix_binding_mismatch.
class BetaThinkingMismatchAllowedInputTransformation { $type = 'thinking_mismatch_allowed'; $path; $reason; }
Always thinking_mismatch_allowed for this entry type.
Where the block is in your request, as messages.{i}.content.{j}:
i indexes the messages array you sent and j that message's content
array — the same form error messages use.
Which binding check the block failed; the block was shown to the model all
the same. Always prefix_binding_mismatch today — the conversation before
the block differs from the conversation it was created in, or the block
carries no record of one on a model that requires it. Were the check
enforced for this request, the block would have been removed or the request
rejected (thinking.block_binding.prefix_mismatch_behavior). A removal also
takes the rest of that turn's consecutive thinking blocks, whereas here each
block is checked on its own, so thinking_mismatch_allowed entries are a
lower bound on what enforcement would remove.
class BetaThinkingTurns { $type = 'thinking_turns'; $value; }
class BetaTokenTaskBudget { $type = 'tokens'; $total; $remaining; }
The budget type. Currently only 'tokens' is supported.

If true, tool will not be included in initial system prompt. Only loaded when returned via tool_reference from tool search.
?string descriptionDescription of what this tool does.
Description of what this tool does.
Tool descriptions should be as detailed as possible. The more information that the model has about what the tool is and how to use it, the better it will perform. You can use natural language descriptions to reinforce important aspects of the tool input JSON schema.
Enable eager input streaming for this tool. When true, tool input parameters will be streamed incrementally as they are generated, and types will be inferred on-the-fly rather than buffering the full JSON output. When false, streaming is disabled for this tool even if the fine-grained-tool-streaming beta is active. When null (default), uses the default behavior based on beta headers.
