Sprout Social API

# Fix list: Sprout Social API

From Anchor Terminal's listing at https://www.anchorterminal.com/tools/sprout-social, the October 2026 research run, assessed 9 October 2026. Grade C, 54.7 out of 100.

This is everything the published grade says the listing lacks, the biggest possible gain to the total first. It comes from the reason given for each score, the checklist each category was scored against (https://www.anchorterminal.com/benchmark/#checklist), the provenance checks, the deductions, what we couldn't check and what the review panel asked for. A fix counts at the next check, once it's public.

For a coding agent working on Sprout Social API: work through the items below in the product, its docs and its public pages. Each category gives the reason for its score, with the points each checklist item earned, and the checklist itself, so the gap is the items that earned less than their points. Change the product, not the wording, and keep a note of what you changed and where it's published.

## 1. Payments & pricing, 20 out of 100, up to 10 more on the total

Why it scored 20: No x402 or other machine payment protocol (0). Plan prices are public and the API is listed on Advanced at $399 per seat a month, with no per-call price (10). A 30-day trial needs no credit card, but whether it includes API access was not established, so half marks (10). A person has to sign up, hold the API Permissions permission and accept the API terms in settings (0).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-payments):

The published rubric, also on the [x402 page](https://www.anchorterminal.com/x402/).

- 40, a machine payment protocol (x402, MPP or L402) on the tool's own endpoints. 10 to 30 when it covers only some endpoints or only goes through a third party, and the note says which.
- 20, per-call or per-unit pricing published without a login. 10 for public plan-only pricing, 0 for "contact sales" or prices behind a login.
- 20, a free tier or trial that doesn't need a card.
- 20, autonomous onboarding, meaning an agent can get access without a person signing up in a browser (keyless use, x402, a programmatic key API).

Payment platforms and agent wallets rarely charge for their own API over a machine protocol, so the first line has steps for them, and the highest one that applies counts. 40 when x402, MPP or L402 runs on all their own endpoints, 30 when it runs on part of their own API, 25 when their merchants can accept one, 20 for running a facilitator, 15 for paying as a buyer, and 0 when the only protocol is their own. Merchant acceptance sits above a facilitator because the platform's own customers can charge agents through it, while a facilitator settles for sellers who wire up the protocol themselves. The counter-argument (a facilitator does more for the protocol as a whole) has a point. Each note says which step applied.

Open-source software you run yourself is scored on its hosted or paid option if it has one. A free, self-hosted package with nothing to buy gets 20, 20 and 20 for the last three lines, and 0 to 40 for the first only if it ships a payment protocol.

## 2. Schema & documentation, 51 out of 100, up to 8 more on the total

Why it scored 51: No OpenAPI file or other machine-readable description was found in the docs (0). The site's llms.txt lists marketing articles and no API page, and the docs are one HTML page with no Markdown twin (2). Each endpoint group states its purpose and has a Limitations section, and the overview lists what the API does not include (14). Request keys are tabulated with example values, limits and a few enumerations such as `media_type`, but filters are strings in a small expression syntax such as `created_time.in(...)` (9). Every endpoint has an example request and response, and a status code table gives a corrective action for each code. The error body is one free-text string (11). Versioning is MAJOR.MINOR with version response headers, and the changelog is dated from November 2020 to 6 October 2026 (15).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-schema):

APIs and MCP servers.

- 25, a machine-readable contract (a public OpenAPI file or similar; for MCP, typed JSON Schema inputs on every tool).
- 10, llms.txt or Markdown docs served for agents.
- 0 to 20, descriptions that say what a tool is for, when to use it and when not to, read from the tool definitions in the source or the API reference.
- 0 to 15, typed inputs with enums, constraints and required fields, and no free-form JSON blobs.
- 0 to 15, examples and documented error responses.
- 15, versioning and a public changelog.

Models are read from the API reference, the OpenAPI file, llms.txt, the structured-output and tool-use docs and the model cards. Frameworks from docs a model can follow, typed interfaces, examples and the API reference.

## 3. Security & auth, 61 out of 100, up to 6.8 more on the total

Why it scored 61: OAuth 2.0 client credentials issue short-lived JWT access tokens, a user-based flow is available, and API tokens are named and can be invalidated. The only scope documented is `organization_id`, so a credential is not limited to reading or to one endpoint group. Credentials travel in the Authorization header only (22). No read-only credential is documented. The API can write only draft posts and media, the app has approval workflows, and API access can be limited to IP ranges per the product security page (12). The messages and listening endpoints return text written by the public, and no guidance on untrusted content was found (2). The app has a customer-facing audit trail of over fifty events. Whether API calls appear in it was not established (8). Responsible Disclosure Policy with a Bugcrowd vulnerability disclosure programme, SOC 2 Type 2, ISO 27001, ISO 27701 and CSA STAR Level 1 on the trust centre. No security.txt and no paid bounty stated (17).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-security):

- 0 to 30, the credential model. 30 for OAuth 2.1 with scopes, or scoped and revocable keys with rotation. 20 for plain revocable API keys. 10 for one all-powerful key. 10 off when a secret can travel in a URL query string as a documented option.
- 0 to 20, read-only or least-privilege modes, and confirmation or approval for destructive actions.
- 0 to 15, prompt-injection posture where the tool returns untrusted content (documented mitigations or guidance). A tool that returns no untrusted content gets 10.
- 0 to 15, audit logs or per-call visibility for the operator.
- 0 to 20, a security programme. security.txt or a disclosure policy, a bug bounty, SOC 2 or ISO 27001, advisories handled in public.

Models are read for retention, whether API data trains models (and whether that's off by default), zero-retention options and certifications. Frameworks for telemetry defaults, approval hooks, guardrails and sandboxing.

## 4. Agent ergonomics, 59 out of 100, up to 6.7 more on the total

Why it scored 59: Messages and posts requests take a `fields` list and return only `guid` without it, and analytics requests name their metrics (20). Paging by page number or `page_cursor`, `limit` up to 100, filters and sort are documented, with a 10,000 result cap on numbered pages (18). The status code table tells the caller what to do for each code and every response carries `X-Sprout-Request-ID`, but there are no machine-readable error codes (11). No idempotency key was found. Post creation is draft-only, which limits the harm of a repeated call, and media parts are numbered so a part can be resent (5). No SDK was found, and every call needs a customer ID looked up first (5).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-ergonomics):

- 0 to 25, context cost. For MCP, the number and size of the tool definitions (25 for ten or fewer compact tools, 15 for 11 to 30, 5 for more than 30, plus up to 10 back for toolsets, dynamic loading or read-only subsets). For APIs, whether responses can be sized (field selection, limits, summaries).
- 20, pagination, filtering and output-size controls.
- 20, actionable, documented error responses, codes and messages an agent can recover from.
- 20, idempotency or safe retries, and for MCP the `readOnlyHint` and `destructiveHint` annotations.
- 15, sensible defaults, few required parameters, and official SDKs in at least two languages.

Models are read for tool use, structured output, prompt caching, context length, batch and SDKs. Frameworks for how much code and how many defaults a tool-calling agent with MCP needs.

## 5. Reliability, 71 out of 100, up to 5.8 more on the total

Why it scored 71: Hosted lines. A public status page on Atlassian Statuspage with a separate Sprout Social API component and incident history (20). The history feed shows six incidents in the 90 days to 9 October 2026. Four were traced to Meta, Reddit or Threads, two were on Sprout's Trellis assistant (one a 22-minute outage on 6 August), and one on 20 July was platform performance trouble resolved in about two hours with no severity stated. None named the API component, so we read the record as minor incidents only (20). Rate limits are published as 60 requests a minute and 250,000 a month (15). 429 is documented with the advice to slow down, and the media upload section advises exponential back-off on 5xx, but no `Retry-After` header or idempotency key for post creation was found (6). No SLA was found in the Terms of Service or Developer Terms. The security page gives 99.9 per cent uptime as an internal target (0). The API is not labelled beta (10).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-reliability):

Hosted APIs, MCP servers, models and platforms.

- 20, a public status page with component history (Statuspage, Instatus, BetterStack or the vendor's own).
- 0 to 30, the incident record for the last 90 days on that page. 30 for a clean record or trivial incidents only, 20 for minor incidents only, 10 for one major outage (an hour or more of a core API down, or errors across the board), 0 for several. 5 when there's no history we could read, and the note says so.
- 15, rate limits documented with numbers.
- 15, documented 429 or overload handling (Retry-After, backoff guidance), and idempotency keys or safe-retry guidance where writes are involved.
- 10, an SLA published for any paid tier.
- 10, the surface agents use is generally available, not beta or preview.

Local packages, SDKs, frameworks and stdio MCP servers.

- 20, installs from an official package with supported runtimes stated.
- 25, a public CI and test suite, passing on the default branch.
- 0 to 25, open crash or regression issues relative to activity (25 for few and handled, 0 for many, old and unanswered).
- 15, semver discipline and breaking changes called out in a changelog.
- 15, version 1.0 or later, or declared stable.

Protocols are read from their reference implementations, the public facilitators or servers, spec stability and test vectors.

## 6. Maintenance & community, 38 out of 100, up to 5.4 more on the total

Why it scored 38: The newest changelog entry is dated 6 October 2026 (30). It is the only dated entry in the 90 days to 9 October 2026. The two before it are 15 June and 10 June (0). A public changelog, a help centre and a community site are linked. The Developer Terms say they entitle the developer to no support for the API (8). No official SDK was found (0). No package to assess (0).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-maintenance):

- 0 to 30, time since the last release, or the last published model or API change for a closed service. 30 within 30 days, 20 within 90, 10 within 180, 0 older.
- 20, at least three releases or dated changelog entries in the last 90 days.
- 0 to 25, responsiveness. Issues and pull requests answered on GitHub (the open issues and how recent the replies are). For closed services, a public changelog and a support or community channel that answers, 0 to 15.
- 15, presence in the official MCP registry under a verified namespace (MCP servers), or current official SDKs (APIs and models).
- 10, package health, current dependencies and CI.

Models are read for deprecation notice periods and model churn rather than release counts.

## 7. Transparency & trust, 70 out of 100, up to 2.6 more on the total

Made of editorial 55, provenance 85.

Why it scored 70: Closed service with published Developer Terms (9 May 2024) and Terms of Service (9 May 2025) from Sprout Social, Inc. (15). The privacy policy of 16 September 2026 covers the services and states the processor role, the Terms of Service allow account content to be removed within 30 days of termination, and the docs say uploaded media is kept for 24 hours. The policy gives no retention periods, and the DPA is a PDF we did not read (20). The changelog carries dated notices of removed metrics, most of them forced by Meta. The Developer Terms promise only reasonable efforts, when possible, to give notice that a version will stop being supported (8). Hosting is disclosed to the cloud region, all in the United States. The privacy policy lists service providers by category, and a named sub-processor list was not found on the pages read (12).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-transparency):

- 0 to 30, source availability and licence clarity. 30 for open source under an OSI licence, 15 for closed with clear terms, 0 for unclear terms.
- 0 to 30, data handling and retention statements that agree with each other (privacy policy, DPA, retention periods, subprocessors).
- 0 to 20, a deprecation policy or notices with dates.
- 0 to 20, telemetry disclosed with an opt-out (local software), or subprocessors and data locations disclosed (hosted).

The other half of Transparency and trust is the provenance score, computed from checked facts (below). The category score is the mean of the two.

Provenance checks not met in full (half of this category, computed from checked facts):

- Terms of service: read, states 6 of the 7 things a reader expects, and has 2 clauses that cost points (5.1 of 10)
- security.txt: not found (0 of 10)

## What we couldn't check

What we couldn't read counted as absent. Publishing it on a page a plain HTTP fetch can read (not only in a browser) lets the next check count it.

- unchecked: whether the 30-day trial includes API access. The pricing page lists the API on Advanced and the docs send readers to sales or support, so Payments takes half marks for the trial
- unchecked: the Data Processing Addendum (a PDF on media.sproutsocial.com) and the Customer Trust Portal at trust.sproutsocial.com, so a named sub-processor list and retention periods may exist that we did not read
- unchecked: the Bugcrowd programme page, so whether rewards are paid is not established
- unchecked: the help centre at support.sproutsocial.com, which the docs link for plan requirements, media limits and audit trail details
- unchecked: whether API calls are recorded in the audit trail
- The status feed gives no severity for the 20 July 2026 performance incident (09:46 to 11:39 CDT). Read as a major outage it would lower Reliability by 10
- The lead was right about the interface. One correction, the API creates draft posts only and cannot publish, so `social.post` and `social.schedule` are left out of the capabilities
- The Developer Terms forbid monitoring the API's availability, performance or functionality for benchmarking (section 3s), combining the API with software not authorised by Sprout Social (3l) and testing the vulnerability of its systems (3o). No deduction taken. The owner should read these before any probe is run
- The docs name no MCP server, SDK or OpenAPI file. We did not search beyond the pages the docs and the main site link

## Weaknesses

- Posts can be created only as drafts (`is_draft: true`), so the API cannot publish or schedule a post without a person in Sprout
- API access is listed on the Advanced plan at $399 per seat a month and on Enterprise, with no per-call price
- No OpenAPI file, SDK or MCP server was found in the reviewed documentation
- No idempotency key on post creation, and no `Retry-After` header documented for 429 responses
- The Developer Terms of 9 May 2024 forbid monitoring the API's availability or performance for benchmarking, and combining the API with software Sprout Social has not authorised. Recorded as a fact with no deduction. It matters before any probe is run

## What costs an agent a turn today

The notes we give agents before they call it. Each one is a workaround an agent shouldn't need.

- Call `GET /v1/metadata/client` first for the customer ID, then `GET /v1/<customer ID>/metadata/customer` for profile and group IDs. Every other path needs them
- Send `is_draft: true` on `POST /v1/<customer ID>/publishing/posts`. Tell the user the draft waits in the Sprout calendar for a person to publish
- Name the `fields` you want on messages and posts requests. Without the list only `guid` comes back
- Stay under 60 requests a minute and 250,000 a month, and back off on 429 on your own because no `Retry-After` is documented
- Check the response when a draft names several profiles. A profile that cannot take the attached media is dropped with no error

## When it's done

Send what changed and where it's published as a dispute (https://www.anchorterminal.com/builders/#disputes, or `POST https://www.anchorterminal.com/api/v1/contact` with `"kind": "dispute"`). Disputes are answered in public, and the listing is checked again by the same checklist. Paying for an audit or a listing claim changes nothing here.
