Amazon Nova 2 Sonic vs PlaceCall

Amazon Nova 2 Sonic 95

Hosted reading. AWS Health Dashboard with per-service, per-Region history (20). The dashboard history file (newest event 30 October 2026) lists no Bedrock event in the 90 days from 8 August, and the 3 September us-west-2 event names STS, Connect and IAM Identity Center, not Bedrock. The public dashboard records broad events only, so 25 of 30, as amazon-nova-embeddings was read. Quotas published, 20 concurrent requests per Region, not adjustable (15). The stream API lists ThrottlingException (429), ServiceUnavailableException (503), ModelTimeoutException (408) and ModelStreamErrorException (424), Bedrock's troubleshooting guide advises backoff with jitter, and the 8-minute connection limit comes with a session-continuation sample (15). Bedrock's SLA of 99.9 per cent a month per Region for model APIs, as read for amazon-nova-embeddings on 1 November (10). Generally available since 2 December 2025 (10). 20 + 25 + 15 + 15 + 10 + 10 = 95.

PlaceCall 45

Read with the hosted lines. No status page was found on voygr.tech or in the repository, and status.voygr.tech still does not resolve (0). With no published history the incident line takes 5. The skill in the repository publishes rate limits of 10 requests a second and 120 a minute on free and paid keys, plus a daily call ceiling (15). It says to honour Retry-After on 429 and resume_at on a 503 for maintenance, and every POST /calls carries an Idempotency-Key whose replay returns the stored response with Idempotent-Replayed: true (15). No SLA for any tier (0). Nothing in the skill, README or product page calls the API beta or preview (10). api.voygr.tech's robots.txt now disallows ClaudeBot and names neither Claude-User nor Claude-SearchBot, so the 17 October readings of its OpenAPI spec, llms.txt, llms-full.txt, docs, checkout pages, /v1/pricing and protected-resource metadata are struck, and these lines now rest on the skill repository. 0 + 5 + 15 + 15 + 0 + 10 = 45.

Amazon Nova 2 Sonic 10

No x402, MPP or L402 (0). The Nova and Bedrock pricing pages carry a speech-to-speech table drawn by script, so the per-token prices weren't read and this line scores absent, which is our reader's limit and not the vendor's (0). New accounts get up to $200 in Free Tier credits, and the Free Tier FAQ says most new customers need no payment method, read as half on the other AWS listings (10). A person signs up for an AWS account in a browser (0). Total 10.

PlaceCall 50

No x402, MPP or L402. A 402 from POST /calls is a quota_exceeded error with needed_credits and a checkout_url, not a payment challenge (0). The product page publishes $0.10 per successful call, $0.096 or $0.09 on the 2.5K and 5K credit packs, and $0.05 per answered place suggestion (20). 250 free calls (2,500 credits) on a new account, and both the MCP sign-in and the email-code sign-up create it with no card step (20). A key is issued by POST /signup and a six-digit code sent to the user's email, so an agent with its own inbox can get one. The MCP route needs a person to sign in, and buying credits goes through Stripe checkout (10 of 20). 0 + 20 + 20 + 10 = 50.

Amazon Nova 2 Sonic 79

Closed model under the AWS Service Terms, with Apache-2.0 SDKs and samples (15). Bedrock stores no inputs or outputs by default and model providers can't see them, Sonic isn't on the abuse-detection page's list of models whose traffic is stored, and section 50.3 doesn't list Bedrock among services whose content improves AWS services, as read for amazon-nova-embeddings on 1 November (22 of 30). Bedrock's lifecycle policy for models launched before 7 September 2026 promises 12 months and a Legacy period of at least 6 months, but the March and May refreshes changed the model in place under the same ID (15 of 20). Regions are listed, with sub-processors not read (12 of 20). Total 64.

PlaceCall 50

Closed service with dated API terms (last updated 23 October 2026), and the skill and manifests are MIT (15). The API terms and the privacy policy (6 October 2026) agree on 90 days' retention for recordings and transcripts. A DPA is available only by negotiation, the privacy policy names VOYGR an independent controller of call recipients' data for its own purposes, and it allows de-identified data to be used and shared (20 of 30). The terms reserve the right to change or remove endpoints with or without notice and promise no backward compatibility. The skill marks outcome_type deprecated with no date, and the merged-transcript endpoints were removed with no dated notice (3 of 20). No subprocessor list or data locations. The privacy policy names only categories of service providers (5 of 20). 15 + 20 + 3 + 5 = 43.

Amazon Nova 2 Sonic 50

Read as a model. The newest dated change is the May 2026 refresh, completed on 28 May, 162 days before this check (10). No Sonic release note or document history entry in the 90 days from 8 August. The pre-alpha Python SDK shipped 0.9.0, 0.10.0, 0.11.0 and 0.12.0 in the window, counted half (10 of 20). Release notes, document history, re:Post and AWS Support (10 of 15). The JavaScript Bedrock runtime client is current at 3.1163.0, while the Python route is pre-alpha (10 of 15). The SDKs ship on AWS's release train; CI not read (10). Total 50.

PlaceCall 74

Plugin version 6.5.1 went into all five manifests on 28 October 2026 with a fix to the skill's polling, and the API terms were updated on 23 October (30). In the 90 days from 6 August the repository shipped nine plugin versions, 6.0.0 (26 August) to 6.5.1 (28 October), one of them tagged (v6.0.2, 2 October). Each version changes the skill's content, so none is packaging only and each counts in full, as fullstory's and Bland's plugin versions do (20). The API is closed. There is a support address and a founders' address but no public changelog, and the GitHub issue tracker could not be read from this session (6 of 15, the closed-service reading). Listed in the official MCP registry under the verified io.github.voygr-tech namespace since 2 October 2026 (15). The repository holds no CI and no code to build. Its five manifests agree on version 6.5.1 (3 of 10). 30 + 20 + 6 + 15 + 3 = 74.

Amazon Nova 2 Sonic 75

The Bedrock service model types InvokeModelWithBidirectionalStream, but the Sonic events inside it (session, prompt, content, tool and usage events) are JSON payloads documented only in the guide, with no schema file (12 of 25). llms.txt and Markdown copies of the Nova 2 guide (10). Guides on the event lifecycle, barge-in, turn-taking, async tools and chat history say when and how to use each (16 of 20). Event fields are documented as JSON examples and tables, not typed schemas (10 of 15). Sample repositories in several languages and the API's exceptions with HTTP codes (12 of 15). Release notes and document history, with in-place model refreshes and a versioned model ID (15). Total 75.

PlaceCall 57

No machine-readable contract can be read today. api.voygr.tech's robots.txt now disallows ClaudeBot and names neither Claude-User nor Claude-SearchBot, so the 17 October readings of its OpenAPI spec, llms.txt, llms-full.txt, docs, checkout pages, /v1/pricing and protected-resource metadata are struck, and no copy of the spec sits on voygr.tech or in the repository, so the contract line is unread and not credited (0). The repository's SKILL.md, AGENTS.md and llms-install.md are Markdown references written for agents (10). The skill says when to use each route and when not to, such as never re-dialling a place_call that timed out and polling instead of waiting for transcript_ready (16 of 20). It lists the 13 accepted languages, the four intents with their required slots and the length limits on the notice fields, but slots stays a free-form object (11 of 15). curl examples for each route and a table of error codes with their meaning (15). Plugin versions in five manifests and dated API terms, but no API changelog (5 of 15). 0 + 10 + 16 + 11 + 15 + 5 = 57.

Amazon Nova 2 Sonic 64

Scored as an API. Responses carry transcripts of both sides and usage events, chat history is capped at 200 KB and can be injected once per session (15 of 25). Output controls are voice, turn-taking sensitivity and text or audio input (12 of 20). Typed exceptions with HTTP codes, while errors inside the event stream are less documented (15 of 20). Asynchronous tool calls let the model keep talking, and AWS samples show how to resume after the 8-minute limit, with nothing on repeating tool side effects after a reconnect (12 of 20). A session needs a sequence of start events before audio. The JavaScript SDK is current, but the Python SDK the quickstart uses is pre-alpha and needs Python 3.12 (10 of 15). Total 64.

PlaceCall 81

Four MCP tools per the README and the skill (suggest_places, place_call, get_call_result, answer_question), so context cost is small (25). GET /calls takes limit, lists most recent first without transcripts, and the event feed resumes from an after_event_id cursor, but no filters on the call list were found (12 of 20). Errors carry an error_code and a hint, a 422 for missing slots lists each one with a suggested_question, and a 402 names needed_credits (20). Idempotency keys on POST /calls with 409 idempotency_conflict, idempotency_in_progress and idempotency_state_unknown answers, and a retry procedure that lists calls before re-dialling. MCP tool annotations were not readable (16 of 20). A call needs only target_phone and brief, with language defaulting to auto. No SDK packages in any language, only plugins, a skill and the API (8 of 15). 25 + 12 + 20 + 16 + 8 = 81.
